How do I set the PHP error log location?

The error log location for PHP can be set both globally on the server and on a per-user basis. The exact procedure varies depending on your configuration.

Procedure

Not using PHP-FPM

In WHM

The error log location can only be set globally using WHM. To do so,

1. Log into WHM
2. Navigate to MultiPHP INI Editor
3. Click "Editor Mode"
4. Select the version of PHP you would like to set the log location for
5. Find the error_log location setting
   

   error_log = error_log

6. Change the filename to the desired error log name
7. Save your changes

In cPanel

The most straightforward way to set your error log location is to use the MultiPHP INI Editor in cPanel

1. Log into cPanel
2. Navigate to MultiPHP INI Editor
3. Click "Editor Mode"
4. Select a location
   1. Home directory will set the option for all domains, addons, and subdomains configured on the account
   2. A specific domain will limit the change to that domain, or, in the case of an addon domain, the addon and the matching subdomain
5. Add the line

   error_log = "/some/path"

   This should either be a filename, with no leading path, or an exact path within your home directory
6. Save your changes

Using PHP-FPM

In WHM

The only way to adjust this setting is via WHM's MultiPHP Manager

1. Log into WHM
2. Navigate to MultiPHP Manager
3. Find the domain you'd like to change the error log location for
4. Click the "Edit PHP-FPM" link
5. Change the log location in "The error log file (error_log)" relative to the folder "logs" within the user's home directory
6. Save your changes
