SiteGround has implemented a unique server setup that allows each customer to choose which version of PHP to use for his / her account. What is more, the customer can even use different PHP versions for different directories in one and the same hosting account.
The PHP versions currently supported are: PHP 4.4 PHP 5.0, PHP 5.1, PHP 5.2, PHP 5.3, PHP 6.0 and a special additionally secured version of PHP 5.2 with Suhosin patch.
It is really easy to change PHP versions for your website with a web hosting account with SiteGround. All you need to do is follow those step:
1. Log in to cPanel for your account.
2. Go to Advanced section -> PHP Version Change
3. Navigate to the directory you would like to change the PHP version for (note that the change will apply to sub-directories for it as well)
4. Click on the directory name.
5. Select the desired PHP version and click Save.
