he PHP versions currently supported are: PHP 4.4 PHP 5.0, PHP 5.1, PHP 5.2, PHP 5.3, PHP 5.4 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 1H Software section -> PHP Version Manager
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.
That is all.
You can find detailed instructions how to manually change the PHP version for your account below:
Go to cPanel, File Manager and choose “Web Root (public_html/www)”. There create a new file (or edit the existing one) called .htaccess and add the following line:
To switch to PHP 4.4:
AddHandler application/x-httpd-php4 .php .php4 .php3
To switch to PHP 5.0:
AddHandler application/x-httpd-php5 .php .php5 .php4 .php3
To switch to PHP 5.1:
AddHandler application/x-httpd-php51 .php .php5 .php4 .php3
To switch to PHP 5.2:
AddHandler application/x-httpd-php52 .php .php5 .php4 .php3
To switch to PHP 5.3:
AddHandler application/x-httpd-php53 .php .php5 .php4 .php3
To switch to PHP 5.4:
AddHandler application/x-httpd-php54 .php .php5 .php4 .php3
To switch to the secure PHP 5.2 with Suhosin patch:
AddHandler application/x-httpd-php52s .php .php5 .php4 .php3
This setting will apply recursively to all of the subdirectories. In case you’d like to have a different version of PHP in a subdirectory, create a new .htaccess file in it with the directive for the desired PHP version in it.
