<pre><code> &lt;?php
 $urls = file('listhost.txt', FILE_IGNORE_NEW_LINES);
 foreach($urls as $url) {
 $header= get_headers($url, 1);
 echo "$url ====&gt;", $header['Server'].'&lt;br/&gt;';
 }
 ?&gt;
</code></pre>

<p>how to get headers more faster because here it is very slow whene the list is long and no results if the list count is more then 5 hosts
thanks best regard</p>
