PHP is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML. This makes it suitable for embedding small pieces of dynamic content into web pages. PHP is also the technology behind many of the world's most popular open source web applications (including WordPress, MediaWiki and Drupal). This page gives details on how to set up your webspace for use with PHP.
To use PHP, your scripts should have a
You can choose which version of PHP your scripts are executed with via the Hosting section of the Customer Control Panel:
- Click on the Web Settings link for your website.
- Scroll down to the PHP Version control.
By default, PHP scripts will run using the version of PHP provided by the operating system, but you can switch to running a newer version if required.
Using a custom PHP configuration file

Simply name your custom configuration file
.user.ini and place it
in the root directory of your website. Note that the first character of the

You may occasionally come across online documentation which assumes everyone

Custom PHP error pages
As all PHP requests are processed by PHP-FPM, it will generate its own error pages. These are generated and returned directly to the client, bypassing the webserver's normal error pages. This configuration will work fine for most PHP applications (e.g. WordPress) that generate their own error pages.
However, if you would like to use custom error pages with Apache's
ErrorDocument directive, you will need to set these errors to be handled
by the webserver. You can create a file named
.custom-php-errors in the
root of your website to enable this.
For example, for the site
you could run
