PHP套接字 - 不读取输出

我从套接字读取时遇到一些问题。基本上，我可以无错地连接到机器。我可以在没有错误的情况下写入机器。我似乎无法读取输出。PHP套接字 - 不读取输出

下面是我在做什么：

$header1 = chr(0xFF).chr(0xFB).chr(0x1F).chr(0xFF).chr(0xFB).chr(0x20).chr(0xFF).chr(0xFB).chr(0x18).chr(0xFF).chr(0xFB).chr(0x27).chr(0xFF).chr(0xFD).chr(0x01).chr(0xFF).chr(0xFB).chr(0x03).chr(0xFF).chr(0xFD).chr(0x03).chr(0xFF).chr(0xFC).chr(0x23).chr(0xFF).chr(0xFC).chr(0x24).chr(0xFF).chr(0xFA).chr(0x1F).chr(0x00).chr(0x50).chr(0x00).chr(0x18).chr(0xFF).chr(0xF0).chr(0xFF).chr(0xFA).chr(0x20).chr(0x00).chr(0x33).chr(0x38).chr(0x34).chr(0x30).chr(0x30).chr(0x2C).chr(0x33).chr(0x38).chr(0x34).chr(0x30).chr(0x30).chr(0xFF).chr(0xF0).chr(0xFF).chr(0xFA).chr(0x27).chr(0x00).chr(0xFF).chr(0xF0).chr(0xFF).chr(0xFA).chr(0x18).chr(0x00).chr(0x58).chr(0x54).chr(0x45).chr(0x52).chr(0x4D).chr(0xFF).chr(0xF0); 
$header2 = chr(0xFF).chr(0xFC).chr(0x01).chr(0xFF).chr(0xFC).chr(0x22).chr(0xFF).chr(0xFE).chr(0x05).chr(0xFF).chr(0xFC).chr(0x21); 

    $fp = pfsockopen('ServerName',$port,$errno,$errstr,35); 
    if(!$fp) { 
     echo '<p>Error connecting to system.</p>'; 
     echo $errstr . ' (' . $errno . ')'; 
    } else { 
     fputs($fp, $header1); 
     sleep(1); 
     fputs($fp, $header2); 
     sleep(1); 
     fputs($fp, "99\r"); 
     sleep(3); 

     $read = fread($fp, 128); 
     $pos = socket_get_status($fp); 
     echo '<pre>'; 
     var_dump($pos); 
     echo '</pre>'; 
     //$read = fread($fp,$pos["unread_bytes"]); 
     //$read = str_replace("\n","<br>",$read); 
     //$explode = explode("\"",$read); 
    } 
    fclose($fp);

什么是真的怪我的是，socket_get_status（）为0字节的未读，但EOF是假的。似乎与我相当矛盾。

array(7) { 
    ["stream_type"]=> 
    string(14) "tcp_socket/ssl" 
    ["mode"]=> 
    string(2) "r+" 
    ["unread_bytes"]=> 
    int(0) 
    ["seekable"]=> 
    bool(false) 
    ["timed_out"]=> 
    bool(false) 
    ["blocked"]=> 
    bool(true) 
    ["eof"]=> 
    bool(false) 
}

有没有人有任何想法，为什么我不能得到输出？

谢谢！

我看着'阻塞'的值，发现问题。

本质上，当阻塞== true，如上所述，那么返回值将等待变为可用。将其设置为解除封锁意味着该值将立即返回。

stream_set_blocking($fp, 0);
