php exec崩溃，没有输出

Question

I need to check why my exec function stops my php script.

I call a bat file in "exec" function (but i have the problem to with passthru, system and proc_open) in my HTTP query and after 2min i got an error code 500 (with no details). But my bat file is always running in background (i can see files created...) I use it like this :

exec('cmd /c myScript.bat "myParam" 2>&1 &', $output);

In $output i get nothing, in php error_log nothing... I've added this parameters :

ini_set("display_errors", 1);
ini_set("track_errors", 1);
ini_set("html_errors", 1);
set_time_limit(0);
error_reporting(E_ALL);

Same result...

I'm on PHP 7.2 and IIS 8.

OP found found a solution to the 2-minute-timeout issue:

• The problem was in config of IIS, in applicationHost.config.
• I have to change activityTimeOut in correct FastCgi.
