PHP ini_set: Runtime Config Guide

The purpose of the ini_set function is to dynamically change PHP configuration options at runtime. It takes two parameters, the first being the name of the configuration option to be changed, and the second being the specified new value. By calling the ini_set function, you can temporarily modify various PHP configuration options, such as displaying error reports, setting time zones, adjusting memory limits, and more. This allows you to flexibly control the script’s runtime environment to meet specific requirements without affecting global configurations. However, it is important to note that certain sensitive or security-related configurations may be restricted by server-side settings or limitations in the php.ini file.
