add a space between each 4 digits?

[wmguk]

hey,

 

Im trying to get a field output of 1234567890123456 to display as 1234 5678 9012 3456

only this is sometimes there could be anything between 16 and 24 in the original data output

 

any ideas how i can take 4 digits then insert a space? - it will only ever be numbers.

<?php 
$str = '1234567890123456';
$a = str_split($str,4);
echo join (' ', $a);
?>
