php.ini overview

A php.ini file is a simple text file that allows you to adjust your PHP settings. For example, the server comes with a few default settings such as a PHP memory_limit of 90MB. Other limits that are often changed are for PHP execution time and upload size. This article walks you through how to set up a php.ini (phprc) file and add your custom adjustments.

The standard term for this file is php.ini. However, as of PHP 5.3, DreamHost uses a "phprc" file instead. This acts the same way – only the name is different. In this article, only the term phprc is used.

Determine which PHP version your website uses

Before you create a phprc file, you’ll need to know which version of PHP your site is running. The PHP version for each site is displayed on the (Panel > ‘Domains’ > ‘Manage Domains’) page.

You’ll see the version assigned to any domain to the right under the 'Web Hosting' column:

It's highly recommended that you upgrade to PHP 5.6 or 7 as DreamHost will EOL PHP version 5.5 on March 14 2017. Please visit the following pages to view information on how to update to the latest PHP version:

DreamHost pre-installs the following versions of PHP on its servers:

Nginx

All custom phprc files can be created via SSH on your server (VPS or Dedicated) running NGINX. If you need to update your changes on a Dedicated server running NGINX, run the following command under your Dedicated admin user:

[server]$ sudo /etc/init.d/nginx restart

If you receive a 504 timeout on your website, you must stop nginx, kill PHP, and then finally restart nginx. Run the following commands under your admin user to update your settings:

[server]$ sudo /etc/init.d/nginx stop
[server]$ pkill -9 php
[server]$ sudo /etc/init.d/nginx start
