Hi,
Looking for a one-liner to delete all empty elements in an array. I know I can do it with a foreach loop, but I'm hoping that I've missed an existing function in the manual which may already do this, or a simple one-liner to replace the foreach.
<?php
foreach($in as $k => $v) {
if(empty($v)) {
unset($in[$k]);
}
}
?>
