Comma seperated values from array

Post by onion2k »

Someone on a different forum I frequent asked for some code to create a comma seperated list of the values in an associated array, without using the empty entries.

The obvious solution that was first suggested was to iterate around a for..next loop checking each of the array values and concatenating it into a string. But I came up with this rather elegant solution:

Code: Select all

<?php
function not_empty($e){ return !empty($e); }
$string = implode(",",array_filter($array,"not_empty"));
?>
Just thought I'd share. I'd prefer to define not_empty as an anonymous function, but array_filter doesn't like using them as a callback for some reason.

NB: What's up with the tags? They're not working.

I'm working on it - should be restored in an hour or two.
