proc_open is a PHP function used for executing commands and opening file pointers. It is essential in various PHP applications, including popular frameworks and CMS like Laravel and MediaWiki. However, in shared hosting environments, this function is often disabled for security reasons, leading to functionality issues. This article guides resolving proc_open errors in such scenarios, focusing on Laravel and MediaWiki as examples.

Common Scenarios


In Laravel, a PHP web framework, the proc_open error often appears due to specific features like the Flare error reporting service being enabled in debug mode.


MediaWiki, the free and open-source wiki software, proc_open is necessary for tasks such as picture upload and thumbnail creation. Disabling this function can hinder these essential features.

How to Resolve proc_open Errors

Method 1: Specific Application Configurations


Adjust the Flare error reporting service:

  1. Publish the Flare configuration file with php artisan vendor:publish --tag=flare-config.
  2. In config/flare.php, set 'collect_git_information' to false.


Ensure that proc_open is enabled, as it's crucial for image-handling functions. If it's disabled, consult your hosting provider or consider switching to a hosting environment that allows more control over PHP functions.

Method 2: Selective Enabling in cPanel

For users with a cPanel account on a shared server:

  1. Log into your cPanel account.
  2. Select the PHP version used by your application.
  3. In PHP options, find and edit the disabled_function directive to enable proc_open.

Note: This is viable when the server has security features like CageFS.

Method 3: Avoiding proc_open

If enabling proc_open poses security concerns, it's advisable to explore alternative functions or methods within your application that don't require proc_open.


Resolving the proc_open error in PHP applications on shared hosting requires balancing functionality needs with security considerations. The outlined methods offer a way to address this issue safely. Consult with your hosting provider or a server expert for specific configurations.
