Question

I have a comment box on my site , what I want here is if a user writes input (any character) which is more than 20 characters and doesnot put space between them then it should place a space between it.

Like: “asdasdasdasdasdasdasdasd”

Parsed: “asdasdasdasdasdasdas dasd”

I think it can be done with string compare but I want the regex to match it or the full solution. Thanks for any help.

Answer 1

it is called word wrapping.

http://php.net/manual/en/function.wordwrap.php

from examples :

<?php
$text = "A very long woooooooooooord.";
$newtext = wordwrap($text, 8, " ", true);
echo "$newtext\n";
?>

output:

A very long wooooooo ooooord.
