Save output of $_SERVER to file
<p>I use this :</p>

<pre><code>&lt;?php
foreach($_SERVER as $key =&gt; $value){
echo "&lt;b&gt;$key:&lt;/b&gt; $value&lt;br&gt;\n";
}

 ?&gt;
</code></pre>

<p>Which outputs in browser. Is there anyway to redirect output to file and hide it from the browser page ?</p>
