curl_setopt($ch, CURLOPT_NOBODY);

As-tu essayé de mettre cette option :

[php]curl_setopt($ch, CURLOPT_NOBODY);[/php]

function curlGetHeader ($url){
  $ch     = curl_init($url);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_HEADER, 1);
  $page   = curl_exec($ch);
  curl_close($ch);
  $header = substr($page, 0, strpos($page, "\r\n\r\n"));
  return $header;
}

function socketGetHeaders($url){
  $url = parse_url($url);
  $url['port'] = isset($url['port']) ? $url['port'] : '80';
  $url['path'] = isset($url['path']) ? $url['path'] : '/';
  $fp = fsockopen($url['host'], $url['port'], $errno, $errstr, 10);
  if (!$fp) {
    echo "Erreur de socket: $errno - $errstr<br />\n";
    return FALSE;
  } else {
    $header  = "GET ".$url['path']." HTTP /1.1\r\n";
    $header .= "Connection: Close\r\n\r\n";
	
	    $header  = "GET ".$url['path']." HTTP /1.1\r\n";
    $header      .= "Accept: */*\r\n";
    $header      .= "Cache-Control: no-cache\r\n";
    $header      .= "User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.2) Gecko/2008090514 Firefox/3.0.2\r\n";
    $header      .= "Host: $s_Host\r\n";
    $header      .= "Connection: Close\r\n";
    fputs($fp, $header);
  }
    fputs($fp, $header);
    $page = '';
  while (!feof($fp)){
    $page.= fgets($fp, 1280);
    if(strpos($page, "\r\n\r\n")) break;
  }
  fclose($fp);
  return $page;
} 

Bonsoir,

J'essaye de lire un header, malhereusement j'essaye d'optimiser la vitesse, car 4,5 secondes c'est trop long.

En curl tout fonctionne mais c'est leng :

[php]
function curlGetHeader ($url){
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
$page = curl_exec($ch);
curl_close($ch);
$header = substr($page, 0, strpos($page, "\r\n\r\n"));
return $header;
}
[/php]

j'obtiens bien :

[php]

$url['port'] = isset($url['port']) ? $url['port'] : '80';
$url['path'] = isset($url['path']) ? $url['path'] : '/';
$fp = fsockopen($url['host'], $url['port'], $errno, $errstr, 10);
if (!$fp) {
echo "Erreur de socket: $errno - $errstr<br />\n";
return FALSE;
} else {
$header = "GET ".$url['path']." HTTP /1.1\r\n";
$header .= "Connection: Close\r\n\r\n";

$header = "GET ".$url['path']." HTTP /1.1\r\n";
$header .= "Accept: */*\r\n";
$header .= "Cache-Control: no-cache\r\n";
$header .= "User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.2) Gecko/2008090514 Firefox/3.0.2\r\n";
$header .= "Host: $s_Host\r\n";
$header .= "Connection: Close\r\n";
fputs($fp, $header);
}
fputs($fp, $header);
$page = '';
while (!feof($fp)){
$page.= fgets($fp, 1280);
if(strpos($page, "\r\n\r\n")) break;
}
fclose($fp);
return $page;
} [/php]

J'obtiens sa :

[quote]HTTP/1.1 200 OK

X-Powered-By: xxxxxxxxxxxxxxx

et pas filename...

Get_Header() = trop leng.

Donc merci de m'aidé sur la technique fsockopen.
