When you use the exec   function  it is as though you have a cmd terminal open and are typing commands straight to it  Use single quotes like this   str   exec  start  B Path to batch bat    The  B means the bat will be executed in the background so the rest of the php will continue after running that line  as opposed to   str   exec  start  B  C command    result    where command is executed and then result is stored for later use   PS  It works for both Windows and Linux  More details are here http   www php net manual en function exec php

This snippet is from working code   You can trigger bat file not only from Windows GUI or Task Scheduler  but directly from PHP script when you need it  But in most cases it will have execution for 30-60 sec  depending from your PHP configuration  If job in BAT file is long and you don t want to freeze your PHP scripts  you need to fork BAT job as another process using php exe and not be dependable from Apache   This runs in background mode in Windows  seen as separate processes cmd exe and php exe from Task Manager not halting your Apache PHP scripts  The messages produced by your script may be stored and retrieved back via log files   In my case in file scanner php I do some heavy calculations in loop for big array of files which may last for few hours with php function sleep   not to overload CPU     The success poiner result from file   r which you can query via ajax if you want to know success or fauty start  In my case file scanner php writes log file with messages  somefile jpg - OK wich you can load to your UI with AJAX every few seconds to show progress    PHP         Runs bat file in background mode         function run scanner           c  start  b D  Web example com tasks file scanner bat         r pclose popen  c   r          return json encode array  result   gt  r          BAT   echo Off D  PHP php exe D  Web example com tasks file scanner php  gt  D  Web example com tasks file scanner log exit
