PHP « Получение заголовков сервера через fsockopen

Привет, чего-то не могу разобраться в документации указано, что функция stream_get_meta_data() работает с fopen(), fsockopen() and pfsockopen(), с fopen работает, а вот с соединение полученным через fsockopen выдает такое Array ( [stream_type] => tcp_socket [mode] => r+ [unread_bytes] => 0 [seekable] => [timed_out] => [blocked] => 1 [eof] => )

Например,
/** * GeSHi (C) 2004 - 2007 Nigel McNie, 2007 - 2008 Benny Baumann * (http://qbnz.com/highlighter/ and http://geshi.org/) */ .php.geshi_code {font-family:monospace;} .php.geshi_code .imp {font-weight: bold; color: red;} .php.geshi_code .kw1 {color: #b1b100;} .php.geshi_code .kw2 {color: #000000; font-weight: bold;} .php.geshi_code .kw3 {color: #990000;} .php.geshi_code .co1 {color: #666666; font-style: italic;} .php.geshi_code .co2 {color: #666666; font-style: italic;} .php.geshi_code .co3 {color: #0000cc; font-style: italic;} .php.geshi_code .co4 {color: #009933; font-style: italic;} .php.geshi_code .coMULTI {color: #666666; font-style: italic;} .php.geshi_code .es0 {color: #000099; font-weight: bold;} .php.geshi_code .es1 {color: #000099; font-weight: bold;} .php.geshi_code .es2 {color: #660099; font-weight: bold;} .php.geshi_code .es3 {color: #660099; font-weight: bold;} .php.geshi_code .es4 {color: #006699; font-weight: bold;} .php.geshi_code .es5 {color: #006699; font-weight: bold; font-style: italic;} .php.geshi_code .es6 {color: #009933; font-weight: bold;} .php.geshi_code .es_h {color: #000099; font-weight: bold;} .php.geshi_code .br0 {color: #009900;} .php.geshi_code .sy0 {color: #339933;} .php.geshi_code .sy1 {color: #000000; font-weight: bold;} .php.geshi_code .st0 {color: #0000ff;} .php.geshi_code .st_h {color: #0000ff;} .php.geshi_code .nu0 {color: #cc66cc;} .php.geshi_code .nu8 {color: #208080;} .php.geshi_code .nu12 {color: #208080;} .php.geshi_code .nu19 {color:#800080;} .php.geshi_code .me1 {color: #004000;} .php.geshi_code .me2 {color: #004000;} .php.geshi_code .re0 {color: #000088;} .php.geshi_code span.xtra { display:block; }

Вопрос, как получить заголовки ответа сервера используя соединение fsockopen?
0
header php заголовки

1 ответов

Собственно внимательное прочтение документации даст вам ответ на ваш вопрос:
wrapper_type (string) - метка, описывающая реализацию обёртки протокола, наложенного на поток.
wrapper_data (mixed) - специфические для обёртки данные, прикреплённые к этому потоку.

Очевидно, что fsockopen ничего не знает ни о каких обёртках и посему эти переменные пусты.

Заголовки сервера же вы можете получить примерно так:


$url = 'http://i.askdev.ru/images/logo.png';
$tmp = parse_url($url);
$stream = @fsockopen($tmp['host'], 80);
$headers = "GET ".$tmp['path']." HTTP/1.1\r\n";
$headers.= "Host: ".$tmp['host']."\r\n";
$headers.= "Connection: close\r\n";
$headers.= "\r\n";
fwrite($stream, $headers);
$response = '';
while (!feof($stream)) {
  $response .= fread($stream,1024);
}
echo current(explode("\r\n\r\n",$response,2));
