If you use curl option CURLOPT_NOBODY = true to test if distant url is available, any sites can send you an http code 400 like Cdiscount Wsdl :
$ch = @curl_init($wsdl);
if($ch === false)
return false;
@curl_setopt($ch, CURLOPT_HEADER ,true); // we want headers
@curl_setopt($ch, CURLOPT_NOBODY ,true); // dont need body
@curl_setopt($ch, CURLOPT_RETURNTRANSFER ,true); // catch output (do NOT print!)
@curl_exec($ch);
if(@curl_errno($ch)){ // should be 0
@curl_close($ch);
return false;
}
$code = @curl_getinfo($ch, CURLINFO_HTTP_CODE);
Modifying CURLOPT_NOBODY to false, http code sent is 200 otherwise http code is 400 !!!
