Managing hosting account PHP versions
PHP is a server-side programming language that powers many websites and web applications today. It is known for its versatility and ease of use, making it a popular choice for web developers. As a web hosting company, Infinity Domain Hosting provides PHP support for its customers through its hosting plans. These hosting plans come with different PHP versions, and customers may want to switch between these versions depending on their needs. This knowledge base article will guide customers on how to manage their hosting account PHP versions.
Why manage PHP versions?
PHP versions determine the features and functionality available to developers. Newer versions may introduce new features and improvements while older versions may have deprecated functions or security issues. Some applications may require specific PHP versions to work correctly, and this may require customers to switch between PHP versions. Therefore, managing PHP versions is essential for customers who want to optimize their website's performance and functionality.
How to check the current PHP version?
Before switching PHP versions, customers need to check their current PHP version. This information is usually available in the hosting account control panel, specifically the PHP configuration section. Here are the steps to check the current PHP version in cPanel:
- Log in to the cPanel account.
- Scroll down to the 'Software' section and click on 'Select PHP Version'.
- The current PHP version will be displayed on the top right corner of the page.
Alternatively, customers can check the PHP version using a PHP file with the following code:
<?php
phpinfo();
?>
The above code can be saved as a .php file and uploaded to the hosting account. Accessing the file through the browser will display the current PHP version.
How to switch between PHP versions?
Infinity Domain Hosting offers multiple PHP versions, and customers can switch between them through the hosting account control panel. Here are the steps to switch PHP versions in cPanel:
- Log in to the cPanel account.
- Scroll down to the 'Software' section and click on 'Select PHP Version'.
- Select the desired PHP version from the drop-down menu.
- Click on 'Set as current' to apply the changes.
Customers can also switch PHP versions using the '.htaccess' file. The '.htaccess' file is a configuration file used to modify server settings on a per-directory basis. Here are the steps to switch PHP versions using the '.htaccess' file:
- Log in to the hosting account using FTP or cPanel File Manager.
- Navigate to the root directory of the website.
- Create or edit the '.htaccess' file.
Add the following code to switch to the desired PHP version:
# Use PHP 7.4
AddHandler application/x-httpd-alt-php74 .php
# Use PHP 7.3
AddHandler application/x-httpd-alt-php73 .php
# Use PHP 7.2
AddHandler application/x-httpd-alt-php72 .php
# Use PHP 5.6
AddHandler application/x-httpd-php56 .php
The above code is an example of how to switch between PHP versions using the '.htaccess' file. Customers can modify the code to suit their needs.
It is essential to note that not all hosting accounts allow the use of the '.htaccess' file, and customers should check with the hosting provider before using it.
How to check for compatibility issues?
Switching between PHP versions may cause compatibility issues with web applications. It is essential to test the website or web application after switching PHP versions to ensure it works correctly. Here are the steps to check for compatibility issues:
- Log in to the hosting account.
- Create a test page that uses the web application or website features that were previously causing issues.
- Switch to the new PHP version.
4. Test the page and ensure all features are working correctly.
Repeat the process for all pages and features of the website or web application.
It is also important to note that some web applications may not be compatible with the latest PHP versions. In such cases, customers should contact the web application developer or support team for assistance.
