To run properly WordPress PHP Version minimum requirement 5.2.4. Likewise, all other web applications that run on the web have to meet certain minimum requirements to work efficiently. In this post, you will learn how to check the PHP version.
PHP is a powerful programming language for creating websites. If you want to know about the PHP version installed and to collect general information about the web server installation, then it can be achieved by running a simple PHP function “phpinfo();”. PHP stands for Hypertext Preprocessor, it is an open-source scripting language and has been a stable fixture on the server side of WordPress development ever since WordPress was introduced in 2003. Typically, most of the front-end and back-end of your WordPress website runs on PHP.
So, whenever a newer version of PHP is released it is important to upgrade to the latest PHP version. Running an up-to-date version of PHP ensures better performance and a powerful framework for creating a website.
In this post, we are going to discuss in detail how to check the PHP version on which your website is running. So without any further delay let’s begin with the discussion.
Method 1: Using PHPinfo() Function to Check the PHP Version
PHPinfo() is an absolutely helpful function present in PHP. This function is used to return the compiled information about PHP version, server information, PHP environment, OS version information, PHP extensions, PHP license, HTTP header, environment information, MySql version and paths.
To run this function, simply create a file and name it anything i.e. test.php and place it into the root directory of your website. In most linux servers root directory for a website in Public_HTML. Open the test.php file in a text editor and add the PHPInfo function in it.
<?php phpinfo(); ?>
Save the file. Now open “http://yourwebsite.com/test.php” and after running this file you should see an output somewhat like shown below.
However, if you want to know about some specific value corresponds to specific settings then getting that information is quite simple. Let’s say you want to see the settings for memory_limit. Here you see two values where the first value is the set value for the present directory and the second value is the master value. The local value plays a vital role as the local value can override the master value.
Method 2: Check the PHP Version Using the Command Line
You can use the command line to check the PHP version in case you have access to SSH into the remote server. You can also use this method to check the PHP version installed locally. Here are the steps you need to follow to check the PHP version using the command line:
- First of all, type the PHP command as php -v. Notably, the php -v command works on Windows, Linux, macOS, and other supported systems. The output consists of the PHP version number, build date, and copyright information.
Method 3: Check with the Hosting Provider
You can check the PHP version of your WordPress website fro your Hosting Provider. All modern hosting panels i.e. cPanel, Plesk etc display the current PHP version.
