Detailed explanation of how to set php.ini timeout

When using PHP to execute long-running scripts, we often encounter the problem of scripts running for too long. When the script running time exceeds the predetermined time limit, PHP will automatically terminate the execution of the script and return an error message. This time limit is PHP's timeout. By default, PHP's timeout is 30 seconds. For some scripts that require a lot of calculation or processing, this time limit may not be enough, and a longer timeout needs to be manually set.

The following describes how to set the timeout in the php.ini file.

1. Find the location of the php.ini file

In the Linux system, you can use the following command to find the location of the php.ini file:

php -i | grep php.ini

Command After execution, the path to the php.ini file will be displayed, for example:

Configuration File (php.ini) Path => /usr/local/php7/lib
Loaded Configuration File => /usr/local/php7/lib/php.ini

In Windows systems, you can use the search tool to find the php.ini file.

2. Open the php.ini file

Use a text editor to open the php.ini file. Note: The php.ini file is usually a system-level configuration file and requires administrator privileges.

3. Find and modify the following two configuration items

; Maximum amount of time each script may spend parsing request data.
; Default: 60
; Change: 600
max_input_time = 600

; Maximum execution time of each script, in seconds
; Default: 30
; Change: 300
max_execution_time = 300

Generally, modifying the above two configuration items can set the PHP timeout to 10 minutes. Among them,

• max_input_time refers to the maximum running time of the PHP script, in seconds. During this time, the script's input data must be parsed.
• max_execution_time refers to the maximum execution time of a PHP script, in seconds. Within this time, the script must be executed, otherwise the PHP engine will terminate the execution of the script.

It should be noted that the setting of max_execution_time cannot exceed the limits of other components such as PHP-FPM, Web server, operating system, etc. If these components are bounded to a shorter time, then the timeout will also be bounded to a shorter time.

4. Save and restart PHP

After modifying the php.ini file, save and restart PHP.

In Linux systems, you can use the command:

sudo systemctl restart php-fpm

In Windows systems, you can enter in the command line:

iisreset

Or, restart the IIS service in the service manager.

After the above operations, we can set the PHP timeout to the time we need. Of course, setting a timeout that is too long will also put a certain amount of pressure on the server's performance, and it needs to be set appropriately based on the actual situation and needs.
