PHP Fatal error: Maximum execution time of solution

In the development of PHP language, you may encounter the error message "PHP Fatal error: Maximum execution time of". This error message usually occurs when the program execution time exceeds the maximum time allowed by PHP (default is 30 seconds). When the program execution time times out, PHP will automatically stop the program and prompt this error message.

This error often occurs during PHP development, especially when processing large amounts of data or complex calculations. At this time, adjusting the maximum execution time of PHP is a solution.

The following are some methods to solve "PHP Fatal error: Maximum execution time of":

Method 1: Modify the PHP.INI file

Modify the PHP.INI file max_execution_time parameter value. This parameter controls the maximum execution time of the PHP script, in seconds, and the default is 30 seconds. Find the following code in the file:

max_execution_time = 30

Change "30" to the time you need (such as 180 seconds), then save the file and restart the Apache server.

Method 2: Use the ini_set() function

If you cannot modify the PHP.INI file or just need to modify the maximum execution time in a script, you can use the ini_set() function to set it Maximum execution time parameter for PHP. For example, the following code can be added to the beginning of the script or wherever the execution time needs to be adjusted:

ini_set('max_execution_time', 180); //Set the execution time to 180 seconds

Method Three: Use the set_time_limit() function

Another commonly used method is to use the set_time_limit() function, which is used to set the maximum execution time of the script. For example, you can add the following code to the beginning of the script or anywhere where the execution time needs to be adjusted:

set_time_limit(180); //Set the execution time to 180 seconds

Method 4: Optimize the code

If your code takes a very long time to complete when executed, optimizing the code may be a better solution. Some code optimization methods include:

Use more efficient algorithms

Reduce the number of loops and recursion depth

Reduce the number of database queries

Avoid loops Generate a large number of garbage objects

Use caching mechanism and data index, etc.

Summary

The error message "PHP Fatal error: Maximum execution time of" often appears during the PHP development process Appear. If you know the cause of the error, you can solve the problem by modifying the PHP.INI file, using the ini_set() function or the set_time_limit() function. But a better solution is to optimize the code to reduce the time it takes to execute.
