Running and getting the pid of a background process in PHP on Windows

Question

I started the process in the background on an Apache Windows server.

index.php after that:

<?php
$cmd = "C:/xampp/php/php.exe -f test.php";
pclose(popen("start /B ". $cmd, "r"));
echo "OK";
?>

test.php after that:

<?php
sleep(5);
file_put_contents("1.txt", date("Y-m-d H:i:s"));
?>

At that time I want to get the pid, which php -f test.php. When I run index.php, I can see the new php.exeprocess at the command prompt tasklist. How can I get the pid for this background process.

Thank.

Answer 1

This will exit ProcessIDafter completing the task with wmic. You can then save this in a session or in a cookie to move between pages.

$cmd = 'wmic process call create "C:/xampp/php/php.exe -f /path/to/htdocs/test.php" | find "ProcessId"';

$handle = popen("start /B ". $cmd, "r");

$read = fread($handle, 200); //Read the output 

echo $read; //Store the info 

pclose($handle); //Close

Output

ProcessId = 1000
