uhhh... what? Do you even know HTML - to remove the link just remove the anchor tag.

strip_tags()

[eluser]basty_dread[/eluser]
strip tags cannot be used.. because there are still some other links that should not be removed..

Specify the tags as allowable or use preg_replace()

Code:

$pattern = "/<a[^>]*>(.*)<\/a>/iU";

$string = "Welcom to Codeigniter <a href='http://codeigniter.com'>codeigniter</a><br />
<a href='http://mysite.com/index.php/forums/coding/sample'>codeigniter</a>";

$string = preg_replace($pattern, "$1", $string);

This worked great.. Thank's a lot..here is what i've modified..

Code:

$word = "codeigniter";

$pattern = "/<a[^>]*>(".$word.")<\/a>/iU";

$string = "Welcom to Codeigniter <a href='http://codeigniter.com'>codeigniter</a><br />
<a href='http://mysite.com/index.php/forums/coding/sample'>codeigniter</a>
<a href='www.google.com'>google</a>";

$string = preg_replace($pattern, "$1", $string);


echo $string;

Thanks a lot Dyllon
