How to avoid file_get_contents error: "Couldn't resolve host name"
<p>I succesfully fetch websites with </p>

<pre><code>file_get_contents("http://www.site.com");
</code></pre>

<p>However, if the url doesn't exist, or not reachable, I am getting</p>

<pre><code>Warning: file_get_contents(http://www.site.com) [function.file-get-contents]: 
failed to open stream: operation failed in /home/track/public_html/site.php 
on line 773
</code></pre>

<p>Is it possible to <code>echo "Site not reachable";</code> instead of the error ?</p>
