我已经花了一段时间在这上面但是不能让它工作,我道歉,因为我之前提出了一个有关此问题的相关问题,但删除了它,所以我可以做更多的研究来缩小问题,此时我陷入困境,因为我认为我有解决方案,但它没有按我的预期工作..我找到了一个论坛,有人问了一个类似的问题,他们给了下面的代码,我正在尝试..它确实运行脚本,但在进入PHP代码的下一行之前,它仍然等待它完成
proc_close(proc_open ("/var/www/other_scripts/perl/apps/emails_extract_from_url.pl \"$stoopid\"", array(), $foo));
答案 0 :(得分:3)
嘿,我最近一直在使用proc_open,在继续前进之前它永远不会等待它完成。确保指定管道而不只是使用空数组()
$descriptorspec = array(
0 => array("pipe", "r"), // stdin is a pipe that the child will read from
1 => array("pipe", "w"), // stdout is a pipe that the child will write to
2 => array("file", "/tmp/error-output.txt", "a") // stderr is a file to write to
);
并将proc_open指定给变量。
$myProc = proc_open("/var/www/other_scripts/perl/apps/emails_extract_from_url.pl \"$stoopid\"", $descriptorspec , $foo)
然后,您可以使用proc_get_status($myProc);

关于结束的更多信息。
$temp = fgets($this->open_pipes[$thread_id][1], 1024);
if($this->checkFinishedThread($thread_id))
{
fclose($this->open_pipes[$thread_id][1]);
proc_close($thread);
}
function checkFinishedThread($thread_id)
{
$test = stream_get_meta_data($this->open_pipes[$thread_id][1]);
if($test['eof'] == 1)
return true;
return false;

当我玩proc_open时,我的一些代码
我遇到了proc_close(10到30秒)的问题,所以我刚用linux命令kill杀了进程

您需要在命令行参数的末尾添加一个&(&):
proc_close(proc_open ("/var/www/other_scripts/perl/apps/emails_extract_from_url.pl \"$stoopid\" & ", array(), $foo));
