Yes, it is possible to set an infinite execution time for the PHP Script. We can do it by adding the set_time_limit() function at the beginning of the PHP script.
The set_time_limit() function takes only one parameter that is int value which is in seconds and it returns a boolean value. If the script reaches the amount of time given, then it gives a fatal error.
Syntax:
set_time_limit ( int $seconds )
Return Value: Boolean ( True or False )
Default value:30 seconds
For the maximum or you can say for the infinite execution time, we can set the function with the 0 value. If the value is 0 then it will run for an infinite time.
Note: This method will only work if you are allowed to change PHP configuration by the Hosting Server.
Example 1: The following example is of setting the execution time to 40 seconds
PHP
<?php // This will set the time limit to 40 seconds // Default time is 30 seconds set_time_limit(40); $j =1; while ( $j <5) { echo "$j, " ; $j ++; } ?> |
Output:
1, 2, 3, 4,
Examples 2: The following example is of the setting time to maximum(infinite) time.
PHP
<?php // This will set the time limit to infinite (maximum) // Default time is 30 seconds set_time_limit(0); $j =1; while ( $j <50){ echo "$j, " ; $j ++; } ?> |
Output:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49,
