Solution to PHP Fatal error: Maximum execution time of seconds exceeded solution

When using PHP to run a program, sometimes the error message "Maximum execution time of xxx seconds exceeded" will appear, which means that the maximum execution time of the PHP program exceeds the preset time. This problem is very common and will affect the normal operation of the program. This article will introduce several solutions to deal with this problem.

1. Modify the PHP configuration file

In the PHP configuration file php.ini, there is a max_execution_time parameter, which determines the maximum execution time of the PHP program (unit: seconds ). If the execution time of the program exceeds the set value, the above error message will appear.

To solve this problem, you can modify the value of the max_execution_time parameter in the php.ini file. Find the php.ini file and find the following parameters:

max_execution_time = 30

Change 30 to a larger value, for example:

max_execution_time = 300

After the modification is completed, save the file and restart the web server or PHP process pool for the new settings to take effect.

2. Use the ini_set function

The ini_set function can be used in the program to modify the value of the max_execution_time parameter. For example:

ini_set('max_execution_time', 300);

This function can increase the max_execution_time parameter value to 300 seconds. The disadvantage of this method is that if the program has many files, each file needs to write a call to the ini_set function, which will be very troublesome.

3. Increase code execution efficiency

If the program execution time times out, this problem often occurs, which means that we need to consider optimizing the code to improve the execution efficiency of the program.

First of all, you can try to use better algorithms to achieve the task. Second, caching or other methods can be used to avoid repeatedly reading the same data from disk or database.

In addition, you can consider splitting a job that takes a long time to execute into multiple steps and implement a breakpoint resuming mechanism so that the program can resume the previous step and continue execution the next time it is executed.

Summary:

The most fundamental way to solve the "Maximum execution time of xxx seconds exceeded" problem is to optimize the code to make the program more efficient. If optimization fails, you can increase the max_execution_time parameter value by modifying the php.ini file or using the ini_set function. No matter which method you choose, remember to test it in a production environment and add some breakpoints to make sure the program is working properly.
