In response to dotpointer's modification of Jamaz' solution...
Here is a small modification of your function, this adds the emulation of the optional $format
parameter.
<?php
if(!function_exists('get_headers')) {
/**
* @return array
* @param string $url
* @param int $format
* @desc Fetches all the headers
* @author cpurruc fh-landshut de
* @modified by dotpointer
* @modified by aeontech
*/
function get_headers($url,$format=0)
{
$url_info=parse_url($url);
$port = isset($url_info['port']) ? $url_info['port'] : 80;
$fp=fsockopen($url_info['host'], $port, $errno, $errstr, 30);
if($fp)
{
$head = "HEAD
".@$url_info['path']."?".@$url_info['query']."
HTTP/1.0\r\nHost: ".@$url_info['host']."\r\n\r\n";
fputs($fp, $head);
while(!feof($fp))
{
if($header=trim(fgets($fp, 1024)))
{
if($format == 1)
{
$key = array_shift(explode(':',$header));
// the first element is the http header type, such as HTTP 200 OK,
// it doesn't have a separate name, so we have to check for it.
if($key == $header)
{
$headers[] = $header;
}
else
{
$headers[$key]=substr($header,strlen($key)+2);
}
unset($key);
}
else
{
$headers[] = $header;
}
}
}
return $headers;
}
else
{
return false;
}
}
}
?>
