Why replacing XAMPP PHP version?

If you are using XAMPP for PHP development on Windows, there are high chances that you will need to change, upgrade, or even downgrade your XAMPP PHP version to satisfy the compatibility of the PHP package your are developing.

Some example cases requiring XAMPP PHP version replacement including:

• The PHP platform you are developing requires a newer OR older PHP version to run properly;
• The current PHP platform is outdated, or containing security vulnerabilities;
• You want to test for newer PHP features on a newer PHP version;
• You don’t want to download another XAMPP package again (with different PHP version) and have to reconfigure everything.

This tutorial will guide you on how to replace the PHP version of XAMPP on Windows.
*Note: This is for completely replacing the PHP version in XAMPP. To run XAMPP on multiple PHP versions, we will have another in-depth tutorial on how to do that.

Tutorial StartsChanging XAMP PHP version: Step by step

Here are the steps to change the primary PHP version in XAMPP on Windows.

*We assume that you already have XAMPP running properly.

1. Stop XAMPP Apache process

First, we need to stop the Apache process on XAMPP. To do that, you can locate the XAMPP icon under Windows notification area. Then, double click the icon:

On the XAMPP Control Panel dialog, click Stop at the Actions area on Apache to stop the process. The process is stopped when it doesn’t have the light green background anymore.

If for some reasons, the XAMPP icon doesn’t appear on the notification area, you can stop the Apache process using Windows taskkill command. Open Run dialog (Windows + R), type in this command and press Enter (or the OK button):

taskkill /IM httpd.exe

Like this:

Then the Apache process will be stopped.

2. Download new PHP version

Navigate to this official PHP.net Windows download page:

https://windows.php.net/download/

On the right panel, pick the PHP version number + thread support type you want to download.

• For PHP version number, this page only list the latest stable versions (at the time of this article, 7.4.30, 8.0.23 and 8.1.10). If you want to download older versions (eg. PHP5), head to the PHP.net for Windows Archive page:
  https://windows.php.net/downloads/releases/archives/
  Here you will see the old PHP versions, by the format of either .msi (installation package), .zip (extractable package), a lot right? If you’re confused by this archive page, hang on, we’ll point the right package selection shortly, after the next section:
• For PHP thread support type, in short, here is the quick guide on what to pick:
  • If you use native Apache (with LoadModule, or Apache Handler) or IIS , choose the Thread Safe version.
  • If you use Apache with FastCGI or IIS with FastCGI, choose the Non Thread Safe version.

It is recommended to use Apache with FastCGI (fcgi) for handling multiple PHP processes in Windows, however, by default, in XAMPP’s Apache configuration, it uses the native Apache Handler to serve PHP. So, to keep it quick and we assume that people will mostly use default Apache configuration in XAMPP, we will pick the thread safe version.

*If you are already using non thread safe version on your XAMPP, just continue to pick the non thread safe version.

Okay, so, what to download?

After picking the PHP version number and the thread support type that you want, follow this guide to choose what to download:

• If you use newer, stable versions (7.4, 8.0 and 8.1), just locate it on the right panel of the download page, and download the Zip package with the right thread support version.
  For example, if we choose PHP 8.0.16 + thread safe version:

Картинка с сайта: php101.net

• If you use older, archived versions (mainly PHP 5), on the archive page, do a search on the page with this syntax:

php-[version]

After seeing the highlighted results, here are the guides to pick the right version:

• Non thread safe version will have the nts text in the package name, while thread safe version does not have the nts text in the name.
• 32-bit or 64-bit version will have the x86 or x64 text in the package name
• Don’t download the package with the src in the package name (it’s the source codes, we don’t need that)

For example, if we want to pick PHP 5.6.40, thread safe, 64-bit version, this is the one to download:

Картинка с сайта: php101.net

We could finally picked the right PHP package to download! Next, let’s get XAMPP PHP version to be updated.

3. Extract new PHP version to XAMPP

After downloading the PHP package, extract the copy the files into the XAMPP’s php directory.

We recommend backing up the old php directory by renaming the old php directory (to, like php.old) and create a new one to extract the downloaded files into it, so we can quickly revert the version. For example:

Картинка с сайта: php101.net

4. Configure XAMPP to run with new PHP version

The most important step is to configure XAMPP, or more precisely, configure XAMPP’s Apache for it to work with the PHP version we downloaded. Depends on the major PHP version you want to replace, there are different ways to do that to make it work properly.

4.1. Replace the same major PHP version (eg. 7.4.24 to 7.4.25)

In most cases, changing PHP with the same major version will not require any Apache configuration. This assumes that the thread support version is still the same, and XAMPP has been running properly.

In this case, you can just replace the PHP package files (or backup the old directory and create a new one – like the previous step) into XAMPP’s php directory, and it will just work.

4.2. Upgrade/Downgrade major PHP version (eg. 7.4.24 to 8.0.1)

To switch major XAMPP PHP version, some Apache configuration of XAMPP has to be adjusted. Fortunately, this is very easy and straight forward to do.

*One more time, assuming that the PHP thread support version you are replacing is the same.

Open this file in any Windows text editor (Notepad, VSCode, etc. we preferred VSCode):

[XAMPP Directory]\apache\conf\extra\httpd-xampp.conf

*Again, you should backup the file first by copying it to another location. Do not back it up by duplicate the file in the same directory and leave the same .conf file extension, it will cause error when Apache starts (duplicated configuration).

4.2.1. Edit LoadFile on php DLL file

Find this section:

#
# PHP-Module setup
#

In this section, you will see various LoadFile lines, but the main line to pay attention to is the file loading the php[version]ts.dll, for example, this line with PHP 7:

LoadFile "E:/xampp/php/php7ts.dll"

*The path can be different depends on where XAMPP is installed on your computer.

Edit this line, change the DLL file name to the PHP version you already downloaded.
For example, upgrading from PHP 7 to PHP 8:

LoadFile "E:/xampp/php/php8ts.dll"

-OR- Downgrading from PHP 7 to PHP 5:

LoadFile "E:/xampp/php/php5ts.dll"

4.2.2. Edit LoadModule on Apache DLL file

Then, the next edit is the line nearby with LoadModule, this will be diffrent based on XAMPP version.
For XAMPP with different major PHP version bundled, the lines will be different:

// With XAMPP PHP 5
LoadModule php5_module "E:/xampp/php/php5apache2_4.dll"

// With XAMPP PHP 7
LoadModule php7_module "E:/xampp/php/php7apache2_4.dll"

// With XAMPP PHP 8
LoadModule php_module "E:/xampp/php/php8apache2_4.dll"

*The path will be different based on your system.

Edit this line, replace all php[version]_module into php_module. So with php5_module and php7_module, they will be edited to php_module as well. This is for making us easier to replace major PHP version by simply changing the DLL file name, rather than having to editing the php module name.

The later part is the DLL file to edit based on version, with the syntax of php[version]apache2_4.dll. You can simply change it to your version.

For example, downgrading from PHP 7 to 5:

LoadModule php_module "E:/xampp/php/php5apache2_4.dll"

-OR- upgrading from PHP 7 to 8:

LoadModule php_module "E:/xampp/php/php8apache2_4.dll"

4.2.3. Edit IfModule 

Look up all the <IfModule php[version]_module> lines.

• With XAMPP having PHP 8, you don’t have to edit these lines because they are already correct.
• With XAMPP having PHP 5, the line to lookup is <IfModule php5_module>
• With PHP 7, <IfModule php[version]_module>

Edit them all to:

<IfModule php_module>

That’s all we need to edit on this file. Save the file and move on to the next step.

5. Verify that everything works

To check if the adjustments are fully working, start Apache in XAMPP.

Open the XAMPP Control Panel by the notification bar icon, or by the [XAMPP Directory]\xampp-control.exe file. Then, click Start on the Actions panel of the Apache line. If there are no errors showing, we are nearly done.

Next, create a PHP file inside XAMPP’s htdocs folder, put this content into it:

<?php 
phpinfo();

Save the file, and open it on the browser using localhost URL. Check if the PHP version is updated properly. If yes, congratulation! You have done all of the steps properly to change XAMPP PHP version on Windows.

If there are errors showing, double check the steps and file adjustments to make sure everything is applied correctly. We are going to release an article on how to debug PHP errors on XAMPP soon.

This tutorial is now over. Thanks for reading and hopefully it’s helpful for you.

Understanding the Need to Downgrade PHP 8 to 7.4 on Windows

The release of PHP 8 brought significant improvements and new features to the programming language. However, there may be instances where developers and organizations need to downgrade from PHP 8 to the previous version, PHP 7.4, on a Windows operating system. This could be due to compatibility issues with existing applications, plugins, or frameworks that are not yet compatible with PHP 8. Fortunately, the process of downgrading is relatively straightforward and can be accomplished by following a few essential steps. This article will guide you through the process of downgrading PHP 8 to 7.4 on Windows and help you ensure a smooth transition.

Step 1: Removing PHP 8

The first step in downgrading PHP 8 to 7.4 is to remove the existing PHP 8 installation from your Windows machine. To do this, follow these steps:

• Open the Control Panel on your Windows system by typing «Control Panel» in the Start menu search bar and selecting it from the results.
• Click on «Programs» or «Programs and Features» (depending on your Control Panel view).
• Locate the entry for PHP 8 in the list of installed programs. The entry may be labeled as «PHP 8» or «PHP 8.x.x» (where «x.x» represents the version number).
• Click on the PHP 8 entry and then click on the «Uninstall» or «Uninstall/Change» option.
• Follow the on-screen prompts to complete the uninstallation process.

Once you have successfully uninstalled PHP 8, you can proceed to the next step of installing PHP 7.4.

Step 2: Installing PHP 7.4

After removing PHP 8 from your system, you are ready to install PHP 7.4. Here’s how:

• Visit the official PHP website at https://www.php.net/downloads.
• Scroll down to the «Windows downloads» section and locate the entry for PHP 7.4. Choose the appropriate version based on your system architecture (x86 or x64) and thread safety requirements (TS or NTS).
• Click on the download link for the desired PHP 7.4 version to start the download.
• Once the download is complete, run the installer to start the PHP 7.4 installation process. Follow the on-screen instructions to customize the installation according to your preferences.
• During the installation, make sure to select the options to add PHP to the system PATH and enable extensions as needed.
• Once the installation is complete, you should have PHP 7.4 successfully installed on your Windows system.

With PHP 7.4 installed, you are now ready to configure your web server to use the new version.

Step 3: Configuring the Web Server

In order for your web server to use PHP 7.4 instead of PHP 8, you need to update its configuration. The process may vary depending on the web server you are using. Here are the general steps:

Apache

If you are using Apache as your web server, follow these steps to configure it to use PHP 7.4:

• Locate the «httpd.conf» file in your Apache installation directory.
• Open the file in a text editor.
• Find the line that begins with «LoadModule php» or «AddHandler php» (depending on your Apache version) and comment it out by adding a «#» character at the beginning of the line.
• Add a new line with the following code:

# Load PHP 7.4 module
LoadModule php7_module "path/to/php7/bin/php7apache2_4.dll"

# Path to PHP 7.4 installation
PHPIniDir "path/to/php7"

Make sure to replace «path/to/php7» with the actual path to your PHP 7.4 installation directory.

Nginx

If you are using Nginx as your web server, follow these steps to configure it to use PHP 7.4:

• Locate the Nginx configuration file for your server. The file is usually named «nginx.conf» or «default.conf» and is located in the «conf» directory of your Nginx installation.
• Open the file in a text editor.
• Find the section that begins with «location ~ \.php$ {» and comment out the lines within that section by adding a «#» at the beginning of each line.
• Add a new section with the following code:

location ~ \.php$ {
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
    fastcgi_param PHP_VALUE "auto_prepend_file=path/to/php7/php.ini";
}

Make sure to replace «path/to/php7» with the actual path to your PHP 7.4 installation directory.

IIS

If you are using IIS as your web server, follow these steps to configure it to use PHP 7.4:

• Open Internet Information Services (IIS) Manager on your Windows system.
• Click on your server name in the left-hand pane.
• Double-click on the «Handler Mappings» feature.
• Locate the entry for PHP or FastCGI in the list of handler mappings.
• Right-click on the entry and select «Edit».
• In the «Executable» field, enter the path to the PHP 7.4 CGI binary.
• Click «OK» to save the changes.

After configuring your web server, restart the web server to apply the changes and ensure that PHP 7.4 is now being used.

Step 4: Testing the Downgraded PHP Version

Once you have completed the steps above, it is important to test your downgraded PHP version to ensure everything is functioning as expected. Here are a few ways to test:

• Create a PHP file with the following content:

<?php
phpinfo();
?>

• Save the file with a «.php» extension (e.g., «test.php»).
• Place the file in your web server’s document root directory.
• Access the file in your web browser (e.g., http://localhost/test.php).
• You should see the PHP information page, which displays the PHP version as 7.4.x.

If the PHP version displayed on the information page is 7.4.x, then congratulations, you have successfully downgraded PHP 8 to 7.4 on your Windows system. If not, double-check your configuration and ensure that you have followed all the steps correctly.

Remember to update any necessary configuration files and project dependencies that may be affected by the downgrade to PHP 7.4. Additionally, consult the documentation of the frameworks, plugins, or applications you are using to ensure compatibility with PHP 7.4.

By following these steps, you can safely and effectively downgrade PHP 8 to 7.4, allowing you to continue working with your existing codebase and resolve compatibility issues. Keep in mind that it is always advisable to regularly update your applications and plugins to ensure they are compatible with the latest versions of PHP and other dependencies.

Have you ever wondered how to upgrade or downgrade your PHP version in XAMPP without having to install another XAMPP software?, Well i have and from most answers i saw online, the best option was to download an updated version of XAMPP, but looking at it, i knew there had to be a better way so i made some research and was able to figure it out. In this article, i would show you how i changed my PHP version from 7.4.15 to 8.0.19.

This is a screenshot of my current PHP version

Картинка с сайта: dev.to

If you don’t know your current PHP version, you can use this link to check it.

STEP 1

Download the PHP version you want to use, you can find the PHP version you want to download from PHP’s download website for windows, but there is something you need to know before downloading any package, the download for a PHP version exists in 2 types — thread safe and non thread safe. Since you are using PHP with XAMPP, you are going to download the non-thread safe version because there is an apache file it has that would be used to configure XAMPP with PHP.

After locating it, download the zip file. If you are running on a 32-bit system, download the non-thread safe version labelled with x86.

Update

Depending on the PHP version you want to change to, you might need to download the Thread safe version instead if you downloaded the non thread safe version, and you didn’t see the Apache file there.

STEP 2

After you have downloaded it, extract the zip file and rename the extracted folder to «php», open the folder to find the apache file i mentioned in step 1 as shown in the image below. Once you have seen it, move the php folder to your xampp folder. Remember to make sure the current php folder in the XAMPP folder is either removed or renamed to something else so that the name won’t conflict with the one you are moving.

Картинка с сайта: dev.to

STEP 3

After moving the php folder into the XAMPP folder, open the folder and look for the php.ini config file. Whenever you download a PHP package, the php.ini file comes in two parts, php.ini-development and php.ini-production. These two config files represent the settings running on your development and production environments. Since you are using XAMPP, you would be using the development config file, so rename that config file to php.ini.

STEP 4

Open your XAMPP control panel. Under the actions option for Apache, look for the config button, click on it and select the Apache (httpd-xampp.conf) config file to open it. This is the file that XAMPP uses to configure PHP properly, look for the following:

LoadFile "C:/xampp/php/php7ts.dll"
LoadModule php7_module "C:/xampp/php/php7apache2_4.dll"

• Change php7ts.dll to php8ts.dll
• Change php7_module to php_module
• Change php7apache2_4.dll to php8apache2_4.dll

NOTE — Search everywhere in the file for «php7_module» and change it to «php_module» as you might need to change it in some places.

STEP 5

After you have done all this, save the changes and restart your server, go back to this url and confirm that your PHP version has changed. if everything was done correctly, you should see that you have successfully changed your PHP version!
