PHP timeout hint fatal error:maximum execution time of 30, solution

PHP execution timeout prompts are as follows:
Fatal error:maximum execution time of seconds exceeded in D:\php\AppServ\www\sum3\test.php on line 5
This error is to say that your PHP execution time has passed the maximum execution time set in the configuration file for 30 seconds

This is not the problem of your program itself, but the system configuration file problem, if your network speed, may be executed again will not have this error, but with this problem can also be modified, PHP execution Timeout solution method There are three kinds:
1. Modify the PHP configuration file, find the php.ini file, it should generally be placed in your C:\WINDOWS directory, and then find max_execution_time = 30;//set to the value you want, in seconds
This line, which is the maximum execution time for a setting of 30 seconds, you can modify this value to change your expectations. (can also be directly set to: Max_execution_time = 0)
2. Use the Ini_set () function, not everyone can modify the php.ini file, then you can use this function to change your maximum execution time limit value, such as:
Ini_set (' max_execution_time ', ' 100 ');
is set to 100 seconds, you can also set to 0, that is, do not limit the time of execution.
3. Using the Set_time_limit () function, Set_time_limit (20) represents the maximum execution time plus 20 seconds, but if PHP executes safe mode, Set_time_limit () will not have results unless you use the first method.

Here are some explanations:
Set_time_limit---Limit the maximum execution time
Set_time_limit
(PH3, PHP4)
Set_time_limit---Limit the maximum execution time
Syntax: void set_time_limit (int seconds)
Description
Sets the number of seconds that a program is allowed to execute, and if the time limit is reached, the program returns an error. Its preset limit time is 30 seconds, the value of max_execution_time is defined in the structure file (in PHP3 called Php3.ini, in the PHP4 is called php.ini), if the number of seconds is set to 0, indicating no time limit.
When this function is called, Set_time_limit () calculates the maximum execution time from zero, that is, if the maximum execution time is a preset of 30 seconds, and it takes 25 seconds to execute the program before calling this function Set_time_limit (20). The maximum time that the program executes will be 45 seconds.
Note: When PHP is executed in safe mode, Set_time_limit () will not have results,
Unless you are shutting down Safe mode or modifying the time limit in the structure file (called Php3.ini in PHP3, called PHP.ini in PHP4).
