If you’re a PHP developer, you need to know how to check your PHP version. This is important because different versions of PHP have different features and capabilities. In this article, we’ll show you how to check your PHP version using different methods.

Method 1: Using PHP Command Line Interface

The PHP command line interface (CLI) is a powerful tool that allows you to execute PHP scripts from the command line. To check your PHP version using the CLI, follow these steps:

  1. Open your terminal or command prompt.
  2. Type php -v and press Enter.
  3. The output will show your PHP version.

Here’s an example:

$ php -v
PHP 7.4.16 (cli) (built: Mar  5 2021 07:10:12) ( NTS )

Method 2: Using phpinfo()

Another way to check your PHP version is by using the phpinfo() function. This function displays information about your PHP configuration, including your PHP version. To use phpinfo(), follow these steps:

  1. Create a new PHP file and name it phpinfo.php.
  2. Open the file and add the following code:
<?php
phpinfo();
?>
  1. Save the file and upload it to your web server.
  2. Open your web browser and navigate to http://yourdomain.com/phpinfo.php.
  3. The output will show your PHP version.

Method 3: Using Server Header Response

The third method to check your PHP version is by using the server header response. This method works only if you have access to the server’s configuration files. To use this method, follow these steps:

  1. Open your web browser and navigate to your website.
  2. Right-click on the page and select “Inspect” or “Inspect Element”.
  3. Click on the “Network” tab.
  4. Refresh the page.
  5. Look for the request that corresponds to your website.
  6. Click on the request and look for the “Response Headers” section.
  7. Look for the “Server” header, which should contain your PHP version.

In this article, we showed you three different methods to check your PHP version. The first method uses the PHP command line interface, the second method uses the phpinfo() function, and the third method uses the server header response. Knowing your PHP version is important because it allows you to use the right features and capabilities of PHP. We hope this article has been helpful to you.
