When you say "display sizes", do you mean you want to know how many characters are in it? In that case use strlen()
<?
$text = "Hello World!";
$text .= " You are a cool place!";
$countsize = strlen($text);
echo $countsize."<br />";
// Output: 34
?>
If that isn't what you meant, then post better details about what you need... If it is, be sure to mark it resolved.
