Fill up an array IF statement

Question

<?php 
if ($handle = opendir('gallery3/var/thumbs/Captain-America/')) { 
    while (false !== ($file = readdir($handle))) { 
        if ($file != "." && $file != "..") { 
            echo "$file\n";?><br/><? 
            echo rtrim($file, '.jpg');?><br/><?
            $names[]=$file;
        } 
    } 
    closedir($handle);
}    
?>

I want to createa an array of the file names that are outputting and also the rtrim elements.

And what's your problem? Btw, I know everyone (me too) says to not output HTML with PHP, but you don't have to follow it that strictly. Readability is important too! — Felix Kling

Seems you already know how to do that. I can see you are adding $file to an array. What prevents you from doing the same with the return value of rtrim($file, '.jpg')? Please be more specific about your question. Give an example of the array you want to get in the end. — Felix Kling

glob (coupled with array_map) may do a better job, but you can create an array, and add matches to it very simply:

$files = array(); // declare
...
$files[] = rtrim($file,'.jpg'); // adding entry
...
print_r($files); // debug output to see it

The glob example:

// with or without the array_map to basename()
$files = array_map('basename',glob('gallery3/var/thumbs/Captain-America/*'));
var_dump($files); // normal files

$files_rtrim = array_map(create_function('$f','return rtrim($f,".jpg");'),$files);
var_dump($files_rtrim); // rtrim version of same files

glob returns the full path i guess.

You can use basename and avoid that easily.
