問題描述

是否可以僅對命令或僅對函數設置時間限制，例如:

Hi is there a possibility to set time limit only to a command or only to a function eg:

function doSomething()
{
    //..code here..

    function1();

    //.. some code here..

}

我只想為function1設置時間限制.

I want to set time limit only to function1.

有退出 set_time_limit 但我認為這設置了整個腳本的時間限制.有人有什么想法嗎?

There exits set_time_limit but I think this sets the time limit to whole script. Anybody any Idea?

推薦答案

set_time_limit() 確實在全局運行，但可以在本地重置.

set_time_limit() does run globally, but it can be reset locally.

設置允許腳本運行的秒數.如果達到了，該腳本返回一個致命錯誤.默認限制為 30 秒，或者，如果存在，php.ini 中定義的 max_execution_time 值.

Set the number of seconds a script is allowed to run. If this is reached, the script returns a fatal error. The default limit is 30 seconds or, if it exists, the max_execution_time value defined in the php.ini.

調用時，set_time_limit() 從零重新啟動超時計數器.在換句話說，如果超時是默認的 30 秒，和 25 秒進入腳本執行調用如 set_time_limit(20) 時，腳本將在超時前總共運行 45 秒.

When called, set_time_limit() restarts the timeout counter from zero. In other words, if the timeout is the default 30 seconds, and 25 seconds into script execution a call such as set_time_limit(20) is made, the script will run for a total of 45 seconds before timing out.

我沒有測試過，但你可以在本地設置，離開時重置

I've not tested it, but you may be able to set it locally, resetting when you leave the

<?php
set_time_limit(0);  // global setting

function doStuff()
{
    set_time_limit(10);   // limit this function
    //  stuff
    set_time_limit(10);   // give ourselves another 10 seconds if we want
    //  stuff
    set_time_limit(0);    // the rest of the file can run forever
}

// ....
sleep(900);
// ....
doStuff();  // only has 10 secs to run
// ....
sleep(900);
// ....

set_time_limit()... 在確定腳本運行的最長時間時，不包括在腳本執行之外發生的活動上花費的任何時間，例如使用 system() 的系統調用、流操作、數據庫查詢等.在測量時間是真實的 Windows 上，情況并非如此.
