无法启动后台进程在Windows IIS服务器中运行php脚本

Question

I am trying to launch a background process( executing php script) using popen / exec.

i tried with proc_open --- but results in infinite loop & terminates after some time with 500 internal error.

with popen/exec -- no error & at the same time background script is not running as well.

my current structure is like :

test.php

$processHandle = popen("start /b php background.php", "r");

background.php

$file = fopen("test.txt","w");
 echo fputs($file,"Hello World. Testing!");
 fclose($file);

i tried through command prompt : php test.php

it's launching the background process, and file gets created

i tried to run the same script through web browser request: it's not working & not giving error as well.

any help please ?

Answer 1

pclose(popen());

or

$var = popen();
pclose($var);
