The php script execution time is related to whether the script runs out of time. The maximum execution time of the php script is 30 seconds.

If the script needs to run for a long time, such as sending a large number of emails, or analyzing a large amount of data to prevent the server from forcibly aborting the program in progress after 30 seconds, change the maximum execution time of the php script.

So how do I change the execution time of php scripts?

Here are three methods:

1. Set it in php.ini

In the php.ini configuration file, the script execution time is specified by the max_execution_time variable. So you just need to set the value of the variable.

Max_execution_time = new numeric value

2. Set it through the ini_set function of PHP

Ini_set is used to set the value of php.ini, which takes effect when the function is executed, and the setting becomes invalid after the end of the script. You can modify the configuration without opening the php.ini file, which is convenient for virtual spaces.

Just use the ini_set function to modify the value of the max_execution_time variable

Ini_set ("max_execution_time", "new value")

3. Set through the set_time_limit function

The set_time_limit function is used to limit the execution time of a page

Set_time_limit (new value)

Description:

In the above three methods, if the value is set to 0, there is no limit, and the script executes until the end of execution.
