How to set a time limit for script execution in PHP?

19 Sep 2025

Answer: Use set_time_limit() or ini_set() to set the PHP script execution time limit to prevent unlimited operation. For example, set_time_limit(60) allows the script to run for up to 60 seconds. Set to 0 to cancel the limit but be cautious; it can also be dynamically adjusted through ini_set('max_execution_time',120), or configure max_execution_time globally in php.ini, and restart the server after modification. Note that shared hosting may restrict modifications, and disabling time limits can easily lead to resource exhaustion. It is recommended to process time-consuming tasks in batches.
