Если на веб-сайт нужно добавить новые функции или найти ошибку, узнайте версию PHP вашего сервера. Для этого запустите простой PHP-файл на своем веб-сервере. Также можно выяснить версию PHP на компьютере — это можно сделать с помощью командной строки или терминала.
-
Воспользуйтесь Notepad++, Блокнотом или TextEdit. Не пользуйтесь мощными текстовыми редакторами, такими как Microsoft Word.
-
Этот небольшой код отобразит версию PHP, если запустить его на веб-сервере.[1]
<?php echo 'Current PHP version: ' . phpversion(); ?>
-
Нажмите «Файл» > «Сохранить как», а затем введите имя файла. Добавьте расширение .php в конец имени файла. Введите простое имя, например, version.php.
-
Приведенный выше код отобразит версию PHP, но если вы хотите получить дополнительные данные, например, информацию о системе, дату сборки, доступные команды, информацию об API и так далее, используйте команду phpinfo (). Сохраните файл как info.php.
-
Возможно, вам придется использовать FTP-клиент, или воспользуйтесь панелью управления сервера. Скопируйте файл(ы) в корневой каталог веб-сервера.

Here are some quick tips on how to check the PHP version on your computer or server.
There are several reasons why you want to check the version of PHP which is installed on your server. For example, you might want to install PHP-based software and to check if the software requirements match the PHP version installed on your server. Or you might be a developer who wants to use a feature which is only available in specific versions of PHP.
There are a lot of different PHP versions, and they have some noticeable differences among them. With every new PHP version, new features are added and others are deprecated, so it’s always good to know the PHP version you’re using.
There are a few different ways to check the PHP version. Mainly, if you have SSH access to your server, you can use the command-line interface to check it. On the other hand, if you don’t have terminal access, I’ll show you how to check the PHP version using the phpinfo function.
Check the PHP Version by Using the Terminal
In this section, we’ll discuss how you could check the PHP version by using the command-line interface (CLI) in a terminal.
Check the PHP Version on Unix, Linux, and macOS
For *nix-based systems—Linux, Unix, and macOS—it just takes a single command to check the PHP version. Go ahead and run the following in your terminal.
You should see an output like the following:
1 |
PHP 7.2.24-0ubuntu0.18.04.3 (cli) (built: Feb 11 2020 15:55:52) ( NTS ) |
2 |
Copyright (c) 1997-2018 The PHP Group |
3 |
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies |
4 |
with Zend OPcache v7.2.24-0ubuntu0.18.04.3, Copyright (c) 1999-2018, by Zend Technologies |
As you can see, this gives you comprehensive information about the PHP version which is installed on your server. In the above output, the 7.2.24 version of PHP is installed on the server.
Check the PHP Version on Windows
For Windows users, the same command is used to check the PHP version. But you might get an error if you don’t set the PATH environment variable first. You can do that by running the set PATH command. Run the following commands, and make sure that you replace the {PATH_TO_PHP_DIRECTORY} placeholder with the directory path where you’ve installed PHP. For example, if you installed PHP in the C:\software\php directory, you need to run set PATH=%PATH%;C:\software\php.
1 |
set PATH=%PATH%;{PATH_TO_PHP_DIRECTORY}
|
2 |
php -v |
If you don’t want to set the PATH environment variable, you could also go to the directory where you’ve installed PHP and run the php -v command from there.
1 |
cd C:\softwares\php |
2 |
php -v |
So that was a brief introduction to the CLI option to check the PHP version. In the next section, we’ll discuss how you could check your PHP version with the phpinfo function.
Check the PHP Version by Using the phpinfo Function
You can also use the phpinfo function, which prints detailed information about the PHP software on your server and its configuration.
This option is especially useful when you don’t have SSH access to the server where your site is hosted. If you want to use this option to check the PHP version on the remote server, all you need is the ability to upload a PHP file, for example with FTP or a web-based portal.
Create a file called php_version_check.php file with the following contents.
1 |
<?php
|
2 |
phpinfo(); |
3 |
?>
|
Upload this file to the root directory of your site. Once you’ve done that, you should be able to access it at the http://example.com/php_version_check.php URL (replacing example.com with your own domain name). It should produce output like that shown in the following screenshot.
phpinfo Security Risks
As you can see, the PHP version is displayed right on the top of the page. Also, it displays a lot of other important configuration information as well. This information can be very useful if you are setting up or debugging a PHP installation. It can also be very useful for hackers, allowing them to pinpoint specific vulnerabilities in your system!
That’s why I strongly recommend you remove this file from the server once you’ve finished checking the PHP version.

phpversion — Получает текущую версию PHP
Описание
Список параметров
extension-
Необязательное имя модуля.
Возвращаемые значения
Функция возвращает текущую версию PHP в виде строки (string).
При передаче в параметр extension
строкового (string) аргумента функция phpversion()
возвращает версию модуля или false, если информации о версии нет или модуль не включили.
Список изменений
| Версия | Описание |
|---|---|
| 8.0.0 |
Параметр extension теперь принимает значение null.
|
Примеры
Пример #1 Пример использования функции phpversion()
<?php// Выводит строку вида 'Текущая версия PHP: 8.3.12'
echo 'Текущая версия PHP: ' . phpversion();// Выводит строку вида '1.22.3' или ничего, если модуль не включили
echo phpversion('zip');?>
Пример #2 Пример работы с константой PHP_VERSION_ID
<?php/**
* Константу PHP_VERSION_ID определяют как число, причём чем больше число, тем новее
* версия PHP. Значение константы определяют выражением, которое приводит предыдущий абзац:
*
* $version_id = $major_version * 10000 + $minor_version * 100 + $release_version;
*
* Теперь через константу PHP_VERSION_ID можно проверять, какую функциональность
* поддерживает текущая версия PHP, для этого не нужно каждый раз вызывать функцию version_compare(),
* чтобы проверить, поддерживает ли функцию текущая версия PHP.
*
* Например, можно определить константы семейства PHP_*_VERSION,
* которые недоступны в версиях до 5.2.7:
*/
if (PHP_VERSION_ID < 50207) {
define('PHP_MAJOR_VERSION', $version[0]);
define('PHP_MINOR_VERSION', $version[1]);
define('PHP_RELEASE_VERSION', $version[2]);// и так далее…
}?>
Примечания
Замечание:
Информацию о версии PHP также даёт предопределённая константа
PHP_VERSION. Дополнительную информацию
о семантических значениях, из которых состоит полная версия
выпуска PHP, дают константы семействаPHP_*_VERSION.
Замечание:
Отдельные модули определяют свой номер версии,
но бо́льшая часть встроенных модулей в качестве своего номера
версии будет использовать версию PHP.

If you're trying to check whether the version of PHP you're running on is sufficient, don't screw around with `strcasecmp` etc. PHP already has a `version_compare` function, and it's specifically made to compare PHP-style version strings.
<?php
if (version_compare(phpversion(), '5.3.10', '<')) {
// php version isn't high enough
}
?>

Note that the version string returned by phpversion() may include more information than expected: "5.5.9-1ubuntu4.17", for example.

PHP is powering hundreds of websites & web applications around the world, and although most of the time it is used on Linux, we can install PHP on Windows 11 or 10 as well. However, after completing the setup or implementing any new version of PHP, it is essential to find out which version of PHP is running on your Windows system.
How to Check PHP version on Windows 10 or 11Check the PHP version using Command prompt or PowershellPHP is not recognized as an internal or external commandCreate a PHP Info () page on Windows
It helps to confirm the web application we are using on our Windows Desktop or Server has satisfied the PHP requirements it needed.
In this quick tutorial, we will find out the way to check the PHP version running on our Windows using the command line.
How to Check PHP version on Windows 10 or 11
Before following the tutorial, make sure PHP has been configured properly on your Windows system. Apart from that you need a command prompt or terminal access.
If you don’t have this programming language on your system yet then see our tutorial on how to install PHP on Windows using the command prompt.
Check the PHP version using Command prompt or Powershell
The best and easiest way to identify the installed PHP version is by using its command line tool. However, to use the user must have access to the Windows command line apps like CMD.
Go to Windows 10 or 11 search box and type CMD or Powershell. You can use any of them. As the icon appears on any of these tools, click on it to run.
Run the given php the command that will help you to check the installed PHP version on Windows 10/11 or any other edition you are using:
php -v
or
php -version
The above command is not just limited to Windows only, even other operating systems users such as Linux or MacOS can use it. As you run the syntax, in return the version and the technical details will be given.
However, the command will only show the default version on the system, not all the available ones, if you have installed multiple.
PHP is not recognized as an internal or external command
Sometimes, if you run the PHP -v and get an error saying PHP is not recognized as an internal or external command on Windows prompt or PowerShell then most probably the installed PHP location is not added in your system’s path.
So, first, open the C drive and find out the path of PHP. By default, it will be: C:\Program Files\php\php.exe however, we have used the Choco to install it, therefore our default path is C:\tools\php
Once you confirmed the location, open the system variables window. For that, go to the search box and type – Edit the system environment variables
Click on it, as the option is available in the search result.
Soon the System Properties will open, here you have to click on the “Environment Variables…” button.
Select the Path from the System Variables area and click on the Edit button to get further options for adding the PHP-installed folder path in your Windows.
Finally, click on the Browse button and navigate to the folder where the PHP is located.
After finding the folder, select it and press the OK button.
Now, open the command prompt or PowerShell to run the common php -v command for showing the version-related details.
Create a PHP Info () page on Windows
Another way to check the version of PHP on Windows 11 or 10 is by using a single line of code that will display all the necessary information including extensions and their versions.
For that on your command prompt or terminal type:
notepad info.php
After that paste the following code and save and close the file.
Now, you may not know PHP comes with its own web server that we can use to test our PHP-based applications. So, in the same directory where you have created the info.php run:
php -S localhost:8000
You will see the PHP’s inbuilt web server will be started on your current Windows command prompt. Now, open your browser and type:
http://localhost:8000/info.php
And you will see a piece of detailed information about your installed PHP version.
