Why are `ini_set(\'max_execution_time\')` and `set_time_limit()` ineffective on a server but work on localhost?

ini_set, set_time_limit, and (max_execution_time) Not Functioning

Question:

Why do set_time_limit() and ini_set('max_execution_time') function correctly on a localhost but fail on another server?

Answer:

The inability to adjust execution time using these functions stems from the PHP runtime configuration setting, max_execution_time, being prohibited from modification via ini_set() when safe mode is enabled.

Explanation:

Many web hosts employ safe mode, a security measure that restricts certain PHP functions. When running in safe mode, attempts to alter max_execution_time using ini_set() are ignored.

The solution to this issue is either to disable safe mode or change the time limit in the php.ini configuration file. Additionally, set_time_limit() is also affected by this restriction in safe mode, with no workaround available.
