See http://php.net/manual/en/function.set-time-limit.php
见http://php.net/manual/en/function.set-time-limit.php
set_time_limit($seconds)
If $secondis set to 0, no time limit is imposed. Note that you should be cautious with removing the time limit altogether. You don't want any infinite loops slowly eating up all server resources. A high limit, e.g. 180is better than no limit.
如果$second设置为0，则不施加时间限制。请注意，在完全取消时间限制时应谨慎。您不希望任何无限循环慢慢耗尽所有服务器资源。上限，例如180总比没有限制好。
Alternatively, you can adjust the time setting just for certain blocks of code and resetting the time limit after the time critical code has run, e.g.
或者，您可以仅为某些代码块调整时间设置，并在时间关键代码运行后重置时间限制，例如
$default = ini_get('max_execution_time');
set_time_limit(1000);
... some long running code here ...
set_time_limit($default);

In .htaccessyou can set these values:
在.htaccess你可以设置这些值：
php_value max_execution_time 1000000
php_value max_input_time 1000000
You can also try this at the top of your PHP script:
您也可以在 PHP 脚本的顶部尝试此操作：
set_time_limit(0);

you can use ini_set()like this:
你可以这样使用ini_set()：
ini_set('max_execution_time', 0);
Setting it to 0 will make your script run forever according to the documentation of the ini-directive.
根据ini-directive的文档，将其设置为 0 将使您的脚本永远运行。
