#12300 [Com]: exec() family problems

ID: 12300 Comment by: me at me dot com Reported By: marv at cyberia dot net dot lb Status: Bogus Bug Type: Program Execution Operating System: WinXP PHP Version: 4.3 New Comment: I'm having the same problem with exec. Am using php 4.2.2 with apache2 on win XP. I am trying to open another .php page using exec. Batch file: test.bat c:/php/php.exe c:/php/hello.php hello.php: echo hello; on command line this works fine. But when i tried : $cmd="test.bat"; echo "Executing command: [$cmd]\n"; system($cmd,$value); echo "Return value is: $value\n"; Browser hangs and when i did ctl+alt+del it shows lots of cmd and php.exe processes. However if the test.bat file was : echo hello then it works fine. Any ideas appreciated :) Previous Comments: ------------------------------------------------------------------------ [2003-04-25 04:47:54] mellott at tin dot it very good work marv, I have lost a lot of time for this problem. ------------------------------------------------------------------------ [2002-12-08 03:20:32] sniper@php.net Not PHP bug. ------------------------------------------------------------------------ [2002-12-07 09:24:41] marv at cyberia dot net dot lb finally got it to work! i couldn't make PHP use cmd.exe in the system32 directory since its not allowed to read from that directory. however, i copied cmd.exe into the script's directory and it worked. putting cmd.exe in php.exe's directory also worked. and i dont need to specify the command as "cmd.exe /c test.bat". using just "test.bat" works just fine. so i guess the whole issue is having cmd.exe readable to php.exe and the simplest way to do that is placing cmd.exe in php.exe's directory. making system32 readable to PHP wouldn't very secure, since you would have to make it readable to all webserver processes. ------------------------------------------------------------------------ [2002-12-06 20:00:54] pollita@php.net Try this: <?php $cmd="c:\\winnt\\system32\\cmd.exe /c test.bat"; echo "Executing command: [$cmd]\n"; system($cmd,$value); echo "Return value is: $value\n"; ?> ------------------------------------------------------------------------ [2002-11-05 06:08:28] twa at carlbro dot dk Maybe this bug duplicates this one: http://bugs.php.net/bug.php?id=18958 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
