[RESOLVED] returning an array from function

[bluto374]

I need to return an array of filenames from the following function. I can't seem to get it to work, I keep getting NULL or blank when I var_dump($f);

test(9); //filename to test for are in array $line[9]
var_dump($f);


function test($b)
{
$in = fopen("datafeed.csv" , 'r');
$out = fopen("../scripts/output.txt", 'w');
	while(($line = fgetcsv($in, 0, ',')) !== false)
	{
	    $search = $line[$b];
	    $basename = pathinfo($search);
	    $i = strlen($basename['basename']);
		$a = '0';
	    chdir("../images/");
		while($i > $a)
	    {
			$filename = substr($basename['filename'].'.'.$basename['extension'], $a, $i);
	        if(file_exists($filename))
	        {
	            $f = array($filename);

			fputcsv($out, $f, ',');
                  return($f);
			break; // Break out of this while
        }
		++$a;
	}
} 
}
fclose($in);
fclose($out);

$f is defined only in the function so not available outside it, easy to fix add

return $f;

in the function

then

$f=test(9);
var_dump($f);

ok you have return but its in an odd place will brake the loop (move it to the end) and you probably want

$f[] = $filename;

not

$f = array($filename);

for whatever reason, no matter where I put the return $f, it only gives me the first value. Urrrrrgggghhhh!

well currently your just overwriting the array, not adding to it.
