Run Command Prompt Commands in PHP

php run command line

how to execute cmd command in php

I'm not sure what shell you are going to get with this function, but you can find out like this:

$cmd = 'set';
echo "<pre>".shell_exec($cmd)."</pre>";

On my FreeBSD 6.1 box I get this:

PS1='$ '
PS2='> '

Very interesting.  Note that the PATH may not be as complete as you need.  I wanted to run Ghostscript via ImageMagik's "convert" and ended up having to add my path before running the command:

$cmd = 'export PATH="/usr/local/bin/"; convert -scale 25%x25% file1.pdf[0] file2.png 2>&1';
echo "<pre>".shell_exec($cmd)."</pre>";

ALSO, note that shell_exec() does not grab STDERR, so use "2>&1" to redirect it to STDOUT and catch it.
