I don't think it's a php specific bug, php read the cookie via apache 
apr_table_get

 
apr_table_get return ", a=1" in your case.

When the browser client send 2 Cookie: in header，the php get first cookie name has a comma in
the fist char。God know know the browser send 2 Cookie in header ?

if (!$fp) {
    echo "$errstr ($errno)<br />\n";
} else {
    $out = "GET /show_cookie.php HTTP/1.1\r\n";
    $out .= "Host: localhost:50080\r\n";
    $out .= "Cookie:\r\n";
    $out .= "Cookie: a=1\r\n";
    $out .= "Connection: Close\r\n\r\n";
    fwrite($fp, $out);
    while (!feof($fp)) {
        echo fgets($fp, 128);
    }
    fclose($fp);
}
