Why is this get parameter not equal to a string?
<p>given a url:</p>

<p>scrape.php?u=http%3A%2F%2Fwww.coldwellbanker.com%2Fagent%3 ...etc</p>

<pre><code>$url = $_GET['u'];
$url2 = 'http://www.coldwellbanker.com/agent?action=detail&amp;agentId=121759&amp;mode=detail';
var_dump($url==$url2);

//This prints out bool(false)
</code></pre>

<p>Why is the $_GET parameter not identical to the string equivalent in single quotes?</p>
