Changing the PHP upload_tmp_dir for a domain isn't working

Symptoms

When setting a custom value for the PHP option upload_tmp_dir, the value isn't applying.

Description

The PHP setting "upload_tmp_dir" can only be changed in the context "INI_SYSTEM" configuration file.

PHP - Constant INI_SYSTEM

This means it has to be directly in a php.ini or httpd.conf. This can be commonly changed via the MultiPHP Manager, as this will modify both user INI_USER and INI_SYSTEM. Depending on how the server is set up, this may need to be configured in different areas or multiple settings to achieve the desired change.

Workaround

For PHP-FPM:

System values such as the upload_tmp_dir must be changed via the user's PHP-FPM pool configuration template.

For LiteSpeed:

The value must be changed in the php.ini after editing the LiteSpeed Configuration in the LiteSpeed console to load system values in LiteSpeed per domain. Please take a look at the following article for more information.

For Apache Mod LSAPI Pro ( CloudLinux ):

In CloudLinux, to use INI files in LSAPI, you need to modify a few settings in the configuration file. The article below provides more details. After applying the LSAPI configuration setting change, the MultiPHP INI Editor will work.

For PHP Selector ( CloudLinux ):

The CloudLinux PHP Selector has a command-line tool to modify settings. You can use the "selectorctl" to modify settings that don't appear in the Selector INI editor interface.
