PHP使用proc_open，以便它不等待它打开（运行）的脚本完成？ [英] PHP using proc_open so that it doesn't wait for the script it opens (runs) to finish?

问题描述

我已经花了一段时间，但不能让这个工作，我道歉，因为我问一个有关的问题，关于这个，但删除它，所以我可以做更多的研究来缩小问题，在这一点我被卡住，因为我认为我有这个解决方案，但它不工作，因为我期望..我发现一个论坛，有人问一个类似的问题，他们给了代码，如下，我试图...它运行脚本，但它仍然等待它完成，然后进入下一行PHP代码

I've spent a while on this but can't get this to work, I apologize as I asked a somewhat related question about this earlier but deleted it so I could do more research to narrow down the question, at this point I am stuck as I thought I had the solution with this but its not working as I expect.. I found a forum where someone asked a similar question and they gave code like below, which I am trying.. it does run the script, but it still waits for it to finish before going to the next line in the PHP code

    proc_close(proc_open ("/var/www/other_scripts/perl/apps/emails_extract_from_url.pl \"$stoopid\"", array(), $foo));

推荐答案

我使用proc_open


我有问题proc_close（10到30秒），所以我刚刚杀死进程使用linux命令kill

Some of my code when i played around with proc_open
I had issues with proc_close (10 to 30 seconds) so i just killed the process using linux command kill
