Use get_headers to obtain the Cookie value of the webpage header.
------ Solution --------------------

$array = array('Set-Cookie: BAIDUID=9AFFEA9B11EC8D358FC1A13A8DCC83F9:FG=1; expires=Mon, 24-Dec-42 16:15:18 GMT; path=/; domain=.baidu.com');
foreach ($array as $value) {
    if (stripos($value, 'Set-Cookie') !== false)
        echo $value;
}

------ Solution --------------------
Get_headers (); the second parameter can use the response title as the key name.

 $ Header = get_headers ('http: // www.baidu.com/', true );
$ C = $ header ['set-cooker'];
// The response header can contain multiple Set-cookies, so they are processed in an array.
If (! Is_array ($ c) $ c = array ($ c );
Foreach ($ c as $ I ){
$ S = explode ('=', substr ($ I, 0, strpos ($ I, ';'), 2 );
$ Cookie [$ s [0] = $ s [1];
}
Var_dump ($ cookie );

Some other websites respond with set-cookie instead of Set-Cookie. So the program still has some bugs that you can implement by yourself, but I recommend you use curl
