I wrote a search script recently, and had the user specify which directories
they wanted searched. You can view that here (Requires free account). I
thought this a better choice as it was easier and more customizable.

As for searching EVERYTHING (which may cause security issues I might add)
without rewriting your script too much, I would suggest you use a function
to get
the subdirectories and then check them with your grep statement.
I threw this together for the task of getting your subdirectories
function Get_Tree($directory)
{
global $dirs;
if (substr($directory,-1) != "/")
$directory = $directory . "/";
$fh = opendir($directory);
while ($file = readdir($fh))
{
if (is_dir($directory . $file) && $file != ".." && $file != ".")
{
$dirs[count($dirs)] = $directory . $file;
Get_Tree($directory.$file);
}
}
closedir($fh);
}
I played with static variables, as the manual says they work with
recursive functions, but didn't have any luck so I just used a global variable.
So you also need:
$dirs = array();
Get_Tree($directory);
$dirs will then be an array filled with all of the subdirectories of the
directory you handed it (Probably something like $directory =
dirname($SCRIPT_FILENAME); )
You should be able to then do your grep statement on the $dirs array in a simple for
loop.
Let me know if you have any problems with any of this =)
