removing html?

[newb]

if a string contains html code, how do you output without it? for example:
[code]
<?php
$string = "<b>hi</b>";
echo $string;
?>
[/code]

the string wont be bold, it will just be 'hi' without the bolding.

Take a look at [url=http://us2.php.net/manual/en/function.strip-tags.php]strip_tags[/url]

just do something like this

[code=php:0]
$string = strip_tags('<b>hi</b>');
echo $string;
[/code]

Oh, ok.
