Ignore html and bbcode?

[newbtophp]

I've created a function to limit the amount of text according to the amount of words.

 

However it ruins html and bbcode tags.. . I only want it to have affect on everything else within $text but not bbcode & html.

 

Heres the code:

<?php

function containText($text, $length) {

        $words= explode(' ', $text); // string to array
    foreach ($words as $word) {
        $break = 0;
        for ($i = 0; $i < strlen($word); $i++) {
            if ($break >= $length) {
                $word= wordwrap($word, $length, '-<br>', true); //add <br> every $length chars
                $break = 0;
            }
            $break++;

        }
        $newText[] = $word; //add word to array
    }
    $text = implode(' ', $newText); //array to string
    
    $text = wordwrap($text, $length, "<br />\n");
    return $text;
}


$text = "PHPfreaks is awesome!!!!!
Lets Party! [img=http://awesome.gif]
<img src=\"image.gif\"> Yay!
<a href=\"http://www.phpfreaks.com\">Woot</a>
[font=2]BIG![/font]";


print containText($text, 10);

?>

This is a common problem when wishing to use a summarised text for list display purposes.

 

As you have no way of knowing when your truncation is going to come smack in the middle of some markup, then the only practical solution is to strip the markup and display the summary text without any internal markup.
