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:

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

On my FreeBSD 6.1 box I get this:

USER=root
LD_LIBRARY_PATH=/usr/local/lib/apache2:
HOME=/root
PS1='$ '
OPTIND=1
PS2='> '
LOGNAME=root
PPID=88057
PATH=/etc:/bin:/sbin:/usr/bin:/usr/sbin
SHELL=/bin/sh
IFS='     
'

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:

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

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

cmd run php file

// terminal run php file
// First run "php" in the terminal, in the path directory
php
// If php works there. Then :
php path_to_file/file_name.php

//This will run your php and print stuff to your console in plain text.
//It's useful for a range of testing and data maniplation purposes. 
//And has the full php cammand line. So potential is up to your imagination.
