PHP Get access page HTTP status Code _php technique

No more nonsense. Directly on the code

Core code:

/**
 * Get HTTP status of remote URL
 * * 
 @version 0.0.1
 * @Author CHENJL * * * 
 @param string $url    remote URL
 * @ param string $data   ture[return HTTP status array] | false[return status value]
 * 
 * @return mixed
/function Getheaders ($ URL, $data =false) {
  $_headers = get_headers ($url, 1);
  if (! $data) {return $_headers;}
  $curl = Curl_init (); 
  curl_setopt ($curl, Curlopt_url, $url);//get Content URL 
  curl_setopt ($curl, curlopt_header,1); Get HTTP header information 
  curl_ Setopt ($curl, curlopt_nobody,1);//Do not return the body information of HTML 
  curl_setopt ($curl, curlopt_returntransfer,1);//return data stream without direct output 
  curl_setopt ($curl, curlopt_timeout,30),//timeout length, Unit seconds 
  curl_exec ($curl); 
  $rtn = Curl_getinfo ($curl, curlinfo_http_code); 
  Curl_close ($curl);
  return $rtn;
}

The above code, by the wind has been two ways to obtain a consolidation of access, to facilitate the different access to the HTTP status scenario needs;

return Result:

# Invoke Case 1:getheaders (' http://www.jb51.net\/\ ', true);
# return Result: 200//Direct return HTTP status Code
 
# call Case 2:getheaders (' http://www.jb51.net/', false);
# return Result:/
