user input problem

[brownfox]

If a user enters this in a text area for example:
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxetc
It gets inserted into my DB as a long string and when I echo this out from a SQL query it can break the page up. Does anyone know how I can check if a string is that long and contains no spaces? It's basically checking for idiot user input...

It's Ok I got it sorted thus:
Example 2. wordwrap() example

<?php
$text = &quot;A very long woooooooooooord.&quot;;
$newtext = wordwrap($text, 8, &quot;\n&quot;, 1);

echo &quot;$newtext\n&quot;;
?>

This example would display:

A very
long
wooooooo
ooooord
