There are several possibilities to check and validate PHP version on Linux. 1. Open a bash shell terminal and use the command “php –version” or “php -v” to get the version of PHP installed on the system.# php --version
PHP 5.4.16 [cli] [built: Mar 7 2018 13:34:47]
Copyright [c] 1997-2013 The PHP Group
Zend Engine v2.4.0, Copyright [c] 1998-2013 Zend Technologies
# php -v PHP 5.4.16 [cli] [built: Mar 7 2018 13:34:47] Copyright [c] 1997-2013 The PHP Group Zend Engine v2.4.0, Copyright [c] 1998-2013 Zend Technologies
As you can see from both the command output above, the system has PHP 5.4.16 installed.
2. You can also check for the package versions installed on the system to get the PHP version.
On RedHat Based Distributions :
# rpm -qa | grep php php-common-5.4.16-43.el7_4.1.x86_64 php-pdo-5.4.16-43.el7_4.1.x86_64 php-mysql-5.4.16-43.el7_4.1.x86_64 php-mbstring-5.4.16-43.el7_4.1.x86_64 php-cli-5.4.16-43.el7_4.1.x86_64 php-gd-5.4.16-43.el7_4.1.x86_64 php-5.4.16-43.el7_4.1.x86_64
On debian based distributions :
# apt list --installed | grep php
3. Let’s create a PHP file with content as shown below. The phpinfo[] function outputs a great deal of information about the state of the current PHP environment, including loaded extensions, compilation options, version, server information, and so on.
# echo "" > /var/www/html/phpinfo.php
4. Now, considering that Apache is installed and working, open a browser and test PHP using address as follow:
//server/phpinfo.php
NOTE: By default, we have PHP 7.2 set on our Shared servers.
To check what PHP version is selected for Stellar or Stellar Plus hosting accounts, go to cPanel > Software section > Select PHP Version menu:You will see the current PHP version above PHP extensions:
If you have Stellar Business go to the Exclusive for Namecheap Customers section >> the PHP Tweaks menu:
There you will see the domain and the PHP version set up for it:
Another way to check PHP version is PHPinfo[] function, commonly used to check the current state of PHP configuration. It can also be used for debugging purposes as it contains all EGPCS [Environment, GET, POST, Cookie, Server] data.
To run the function, follow the steps below:
1. Log into your cPanel account, go to the Files section > File Manager:
For cPanel Basic Theme:
For cPanel Retro Theme:
2. Navigate to the public_html directory, click on +File and create a phpinfo.php file:
3. Find the newly created file in the list and click on Edit in the upper corner menu or right-click on the file > Edit:
4. Add the lines of the code provided below to the file and click on Save Changes:
5. To see the detailed information about the PHP configuration of your account, open //yourdomain.tld/phpinfo.php link in your browser, replacing yourdomain.tld with your main domain name.
NOTE: For the security reasons, do not forget to delete the file once you check all the necessary information.
That's it!
