remove special tag with content

I want to remove a div tag with all its content..so far i' m able to remove tags that don't contain any other tags inside..e.g <b>bla bla bla </b>..However the div tag i want to remove is like <div class="" style=""><tag>bla bla...<other tag/>....</tag></div>..any ideas??

 

Use the strip_tags function;

http://php.net/manual/en/function.strip-tags.php

E.G

<?php

$tagged = '<div class="" style=""><tag>bla bla...<other tag/>abcd</tag></div>';
$stripped = strip_tags($tagged);

print $stripped;
?>

PHP:

Output: bla bla...abcd
