Array Help

[jazappi]

I have been trying to take an array i have, delete the values that do not have 28 chars in them. I suppose the strlen not equal to 28.

But how do I grab the array strip it down to the values I want in it and rename the array and print it.

Does that make any sense at all?

$dir    = 'testfiles';
$files1 = scandir($dir);

print_r($files1); // this the array I need to get rid of some of the values in it. I only want the file names that are 28 chars long.

Any suggestion would be helpful, I have been searching the forums and web for 3 hours now and haven't found much to help me. I may just be searching for the wrong thing.

Thanks in advance for any help.

there is probably a better way, but this may do the trick:

loop across the existing array, and test each element for strlen==28. If the element has strlen==28, add it to a new array, otherwise ignore...something like:

function compact($in){
$y=0;
for($x=0;$x<count($in);$x++){
if(strlen($in[$x])==28){
$out[$y]=$in[$x];
$y++;
}
}
return $out;
}

There probably is a better way...

function foo($var) {
        return(strlen($var)==28);
}

$newarray=(array_filter($myarray, "foo"));
