How to not allow HTML tags

[L3e]

Hey, I am making a news article comment script and I want to code it so that when somebody puts html tags in the comment, it won't execute the html but just display the tags.

In the database I have the comment field set up as
Type: Text
Null: Yes

and in the script I just connect to the database and then echo the variable.

How can I make it so that when echoing the variable it won't execute the html?

Thanks to anyone that helps!

It's a pretty easy thing to do.

$string = eregi_replace("<", "&lt;", $string);
$string = eregi_replace(">", "&gt;", $string);

That will just replace the brackets < and > with the HTML codes for the brackets. Making the code plain text on the page.

or

$find = array('<','>');
$replace = array('&lt;','&gt;');

$string = str_replace($find,$replace,$string);

or htmlspecialchars(). All should work properly.
