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." So the right question may be: How do i redirect the standardoutput under Windows, so that PHP do NOT wait fpr the end of the Programm. I tried som 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 DONT WANT TO WAIT! What do i have to do (under windows) to not wait for the end of the program ??? Previous Comments: ------------------------------------------------------------------------ [2004-11-15 16:54:22] [EMAIL PROTECTED] I don't see any bugs here. It's pretty well expected behaviour. The docs say: "If you start a program using this function and want to leave it running in the background, 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." But your program *waits for your input* (i.e. until you close it), so PHP will wait for it too, 'cause exec() "returns the last line from the result of the command" (c). ------------------------------------------------------------------------ [2004-11-15 14:47:22] stolle at web dot de Description: ------------ I'm using PHP on Apache2 (both: Latest Builds) When starting a Program using "exec()" die PHP-Scripts allways hangs under Windows, until the started program terminates. There is no chance to start f.e. notepad.exe in that way, that notepad runs interaktivly, but PHP continous work. Notepad is just an example, i want to control (start and stop) some Windows-Tasks throug PHP. I tried the latest PHP snapshot-Version as well. Reproduce code: --------------- exec('notepad.exe'); exec( "cmd.exe /c c:/windows/notepad.exe 2>nul: >nul:" ); exec( "c:/windows/notepad.exe 2>nul: >nul: &" ); exec( "c:/windows/notepad.exe 2>nul: >nul:" ); Expected result: ---------------- PHP Script should NOT wait for end of notepad Actual result: -------------- PHP Script wait's for end of notepad ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=30794&edit=1
