Hi, i am accepting a string input from a textarea. My problem is that if a user sticks in a long unbroken string such as "fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff" my entire page will try to fit it. I need to be able to check within a string to see if any of the words within it are larger than a certain number of chars, and if it is break it at the max point.

Hence if someone enters: "I like to addlotsofcharacterstogethertobeaproblematicchild but I am still friendly" the large word would be broken, and a " " would be added.

Thanks!

You can get the length of a string by doing a sizeof. Example:

$string = "blahblahblahblahblahblah";
$length = sizeof($string);

Hope that helps =)

If you want to analyze each word within a string then you will probably want to explode the string and loop through it or better yet, use a regexp with eregi_replace(). I've illustrated the former for you below:

<BLOCKQUOTE><font size="1" face="Verdana,Arial,Helvetica">code:</font><HR><pre>
$maxcharacters = 15; // change to maximum number of characters to accept
$string = explode(" ", $full_string);
$sizeof_string = count($string);
for($i=0; $i < $sizeof_string; $i++) {
if(strlen($string[$i]) > $maxcharacters) {
$string[$i] = " ";
}
}
[/code]
