How do I use preg replace to remove this?
<p>I have a string <code>$test='23487°';</code></p>

<p>How can I remove all the instances of the little circle that appears in the string using preg replace? </p>

<p>What to I enter for the regex to remove it?</p>

<p>EDIT - as Pekka says, str_replace is better I am now using that.  But the little circle is still not recognized by PHP...</p>
