[SOLVED] is this a bad idea $e = substr($post['title'], 0, 40); if there is a chance...

is this a bad idea 

$e = substr($post['title'], 0, 40); 

if there is a chance that title might be less the 40chars long?

 

lets say the title is only 4 chars long, will it add 36 empty spaces? or am i fine using that.

 

Thank you and as always appreciate the help.

<?php 
$sizeOfe = $strlen($e);
$e = substr($post['title'], 0, sizeOfe  < 40 ? sizeOfe : 40);
?>

i don't suppose you've thought about passing it a test string to see? substr() won't pad the string; if the length is longer than the string, it will simply return the string.
