Dividing long strings

[ripman]

Hello,

I'm writing news system with comments. When the user writes new comment, sometimes he want's to destroy pages design by entering strings without spaces for example :

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

How to divide that type of string to save pages' layout ?

This code works nicely:

<?
$usercomments = "Hello there how are you?  This is a looooooooooooooooooooooooooooooooooooooong output";

$maxlength = 20;
$array = split(" ", $usercomments);
$c = count($array);
for ($i=0;$i<$c;$i++) {
	if (strlen($array[$i]) > $maxlength) {
		$output .= substr($array[$i], 0, $maxlength) . " ";
	}
	else {
		$output .= $array[$i] . " ";
	}
}
echo $output;
?>

replace $usercomments with the variable that is being passed from a form. $maxlength is the maximum length that you want to allow a word to be. Basically, this script will cut off a long word to how ever many characters you specify in $maxlength

Happy PHPing 🙂

Using wordwrap() might be what you want.
