Why do ini_set(\'max_execution_time\') and set_time_limit() fail to change configuration on a remote server?

ini_set() and set_time_limit() Ignore Configuration Changes on Remote Server

When using ini_set('max_execution_time', 50) or set_time_limit(50) locally, the ini_get('max_execution_time') function returns 50 as expected. However, on a different server, it echoes the default 30, disregarding the specified setting.

Reason:

The inability to change the max_execution_time configuration with ini_set() and set_time_limit() stems from the presence of safe mode. Safe mode is a PHP configuration that restricts certain operations, including modifying runtime settings like max_execution_time via ini_set().

Workaround:

To circumvent this issue, you have two options:

• Disable safe mode in the PHP configuration (not recommended for security reasons).
• Modify the max_execution_time setting directly in the php.ini configuration file.

Additional Note:

The same restriction applies to the set_time_limit() function, as indicated in the PHP manual:

"This function has no effect when PHP is running in safe mode. There is no workaround other than turning off safe mode or changing the time limit in the php.ini."
