ID: 30794 Updated by: sniper@php.net Reported By: stolle at web dot de -Status: Open +Status: Wont fix Bug Type: Program Execution Operating System: Windows XP SP2 PHP Version: 5.0.2 Previous Comments: ------------------------------------------------------------------------ [2004-12-05 17:14:43] mvel at centrum dot cz Hi, I was the same problem. No one of these below has effect. Like my English :-). exec('cmd /C "ping 147.32.x.x -t"'); exec('cmd /C "start ping 147.32.x.x -t"'); exec('cmd /C "pingIP.bat"'); exec('cmd /C "start pingIP.bat"'); content of pingIP.bat ping 147.32.x.x -t or cmd /c 147.32.x.x -t or cmd /c 147.32.x.x -t so <?php $fp=popen("start InstallLinux.exe","r"); pclose($fp); echo "Hastalavista Gates"; ?> Why "r" and not "w"? I dont know. "r" was in the manual. I think, it is much of a muchness. wella ------------------------------------------------------------------------ [2004-11-19 10:53:49] stolle at web dot de So the right question may be: How do i redirect the standardoutput under Windows, so that PHP does NOT wait for the end of the Programm. I tried some more lines: exec( "cmd.exe /c start c:/windows/notepad.exe <nul: 2>nul: >nul:" ); exec( "c:/windows/notepad.exe <nul: 2>nul: >nul:" ); It's always the same: PHP always wait's for notepad's end. BUT I DON'T WANT TO WAIT! What do i have to do (under windows) to not wait for the end of the program ??? ------------------------------------------------------------------------ [2004-11-15 21:43:16] stolle at web dot de Reopened ------------------------------------------------------------------------ [2004-11-15 21:42:13] stolle at web dot de It seems to be so, that PHP wait's for the last process of the group of child processes to terminate. Is there any way (in PHP) to break that behavour? ------------------------------------------------------------------------ [2004-11-15 21:36:41] stolle at web dot de you have to make sure that the output of that program is redirected to a file or some other output stream or else PHP will hang until the execution of the program ends."
