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]); } } ?>

Though it's not really a one-liner:
[code] while ($key = array_search('', $in)) unset($in[$key]); [/code]

A note I forgot to addi in my previous posting:
You ought to think over what you consider "empty" since empty() would for example return true if the checked variable contained the integer 0 or the string '0'.
My posted line of code recognizes only an empty string as "empty".
