exec statement not executing

[devans725]

The first statement executes fine, the other one doesn't?  Not sure why not?  Statement runs from command line with no errors.  I don't receive any errors when php is run.  I just don't get the results I want.  I know the first statement works because the dumbfile.txt contains the correct information.  The final hello.pdf does not contain the correct information.  Any suggestions will be appreciated.

 

<?php
#!/bin/bash

$state = $_POST["state"];
$gross = $_POST["gross"];

exec ("mysqldump --xml --skip-opt --no-create-info --compact --user=user --password=pass --where=gross='$gross' database_W2 > dumbfile.txt", $result);

exec ("python /home/dir/public_html/draw.py", $result);


echo ("
         <script language=JavaScript>
        <!-- Hide from JavaScript-Impaired Browsers
         parent.location=\"hello.pdf\"
         // End Hiding -->
         </script>
      ");

?>

According to the exec() manual page:

Note that if the array already contains some elements, exec() will append to the end of the array. If you do not want the function to append elements, call unset() on the array before passing it to exec().

It's talking about the second parameter to exec().
