Default condition for while loop?

[bunner_bob]

I'm probably thinking about this the wrong way, but I'm still getting un-dumb about while loops...

My script looks like this:

$match_pattern = 'some_pattern';
$dh = opendir('my_directory_path');
while (false !== ($file = readdir($dh)))
{

// go thru all files in upload directory

if (preg_match($match_pattern, $file))
{
        // do something
        break;
    }
}

This is great as long as there's a match for my pattern, but if there is no match I'd like to execute a different process.

Should I start with a condition like "$match_found = false", and switch it to "true" if a match is found? Or is there a slicker way to do it?

Yes. You can do something like this:

$match_found = false;
while (false !== ($file = readdir($dh))) { 
    if (preg_match($match_pattern, $file)) { 
        // do something
        $match_found = true; 
        break; 
    } 
}
if (!$match_found) {
    // do something
} else {
    // do something
}

You can leave the else out if the third do something has already been done.
