为特定函数/代码块（而不是整个脚本）设置超时？
我有 php 脚本调用 perl 脚本来执行各种操作，有时我会得到它一直持续下去而没有得到响应的情况，这是基于传递给 perl 脚本的变量，我做了很多事情连续的不同的，所以我无法直接调试它，因为我没有来自 perl 的响应...
我真的很想能够将 php 函数或代码块设置为在特定时间后超时秒数..我一直在搜索这个，但还没有找到任何关于如何做到这一点的东西，
我在想这样的东西可以工作，但我不认为它会动态更新 $time 变量，但也许有有办法让它发挥作用吗？任何建议表示赞赏
$time = time();
$timeout = $time + 5; //just as an example
do {
// do stuff
} while ($time < $timeout)
I have php scripts that call perl scripts to do various things and sometimes I get it where it just goes on and on without getting a response back, this is based on the variable that is being passed to the perl script and I am doing a lot of different ones in succession so I can't get really debug it directly since I don't have a response from perl...
I would really like to just be able to set a php function or block of code to timeout after a certain number of seconds.. I have been searching on this but haven't found anything yet on how to do this,
I was thinking something like this could work but I don't think it would dynamically update the $time variable, but maybe there is a way to get this to work? Any advice is appreciated
$time = time();
$timeout = $time + 5; //just as an example
do {
// do stuff
} while ($time < $timeout)

最好的选择是使用 proc_open，休眠超时时间，然后在进程仍未完成时调用 proc_terminate。
请参阅 https://www.php.net/manual/en/book.exec .php 了解有关 proc_* 系列的详细信息。
Your best bet would be to use proc_open, sleep for your timeout amount and then call proc_terminate if the process still hasn't completed.
See https://www.php.net/manual/en/book.exec.php for details on the proc_* family.
好吧，我不太确定这个问题是否会根据我的提问方式得到答案，所以我要做的是执行 perl 调用，其中 php 不等待响应并让 perl 将输出写入到文本文件，然后让 php 在指定的秒数后读取此文件，我认为这是最简单的方法，它仅适用于我在本地服务器上运行的一个小应用程序
Well, I'm not so sure this question would have an answer based on how I asked it, so what I am going to do is do the perl call where php doesn't wait for a response and have perl write the output to a text file, then have php read this after specified number of seconds, I think this is the simplest way to do this, its just for a small app i am running on a local server
