php set_time_limit() sets page execution time_PHP tutorial

The set_time_limit function can temporarily define the execution time of your current page. When set_time_limit(0), the page will be valid forever until the program execution is completed. Let me introduce the usage of set_time_limit.

Syntax: void set_time_limit (int seconds)

Note: When PHP is running in safe mode, set_time_limit() will have no results unless safe mode is turned off or the structure file is modified (called php3.ini in PHP3 and php.ini in PHP4 ) time limit.

Example

The code is as follows

代码如下

复制代码

set_time_limit(1000)

Copy code

set_time_limit(1000)

代码如下

复制代码

require_once('db.php');

$stmt = $db->query($sql);

while ($row = $stmt->fetchRow()) {
set_time_limit(0);
// your code here
}

When this function is called, set_time_limit() will restart the timeout counter from zero. In other words, if the default timeout is 30 seconds and set_time_limit(20) is called when the script has been running for 25 seconds, then the total time the script can run before timing out is 45 seconds.
