PHP Quote Problems

I am always running into problems with quotes in PHP.

Here's the problem

<?php
 echo strip_tags("{LINKDESCRIPTION}"); 
?>

{LINKDESCRIPTION} is a description of a listing on one of my sites. The description can contain all types of text. What happens if the {LINKDESCRIPTION} has a double quote in it? It creates an error. Since this is a user submitted field, I can't really restrict the use of quotes. How can I allow the double quotes? If I make it like

<?php
 echo strip_tags('{LINKDESCRIPTION}'); 
?>

then they can't submit a link with ' in it.

Well, if the value of the information is submitted by a user, then it should be in a variable, in which case the quotes shouldn't matter for an echo. (using it within something like a SQL statement could cause problems though).

As you have it listed below, the string is hard coded, in that case just enter \" for a double quote. If it is in a variable, use the addslashes() function first. See http://us3.php.net/addslashes.
