我正在尝试通过
PHP套接字发送和接收数据.
Evrything还可以,但是当我试图发送数据时,PHP不会发送任何内容(Wireshark告诉我发送的数据长度为0).
我正在使用此代码：
<?PHP $address = 'example.com'; $port = 1234; $sock = socket_create(AF_INET,SOCK_STREAM,SOL_TCP); $sockconnect = socket_connect($sock,$address,$port); $c = 0; do { $c++; $msg = '<test>Xml data</test>'; socket_write($sock,$msg,strlen($msg)); echo socket_read($sock,1024 * 100,PHP_NORMAL_READ); } while ($c < 3); socket_close($sock);
谁能帮我？
感谢您阅读我的问题.
如果你连一次都没有检查错误,你怎么知道一切都好？
<?PHP error_reporting(E_ALL); /* Get the port for the WWW service. */ $service_port = getservbyname('www','tcp'); /* Get the IP address for the target host. */ $address = gethostbyname('www.example.com'); /* Create a TCP/IP socket. */ $socket = socket_create(AF_INET,SOL_TCP); if ($socket === false) { echo "socket_create() Failed: reason: " . socket_strerror(socket_last_error()) . "\n"; } echo "Attempting to connect to '$address' on port '$service_port'..."; $result = socket_connect($socket,$service_port); if ($result === false) { echo "socket_connect() Failed.\nReason: ($result) " . socket_strerror(socket_last_error($socket)) . "\n"; } $in = "HEAD / HTTP/1.1\r\n"; $in .= "Host: www.example.com\r\n"; $in .= "Connection: Close\r\n\r\n"; $out = ''; echo "Sending HTTP HEAD request..."; socket_write($socket,$in,strlen($in)); echo "OK.\n"; echo "Reading response:\n\n"; while ($out = socket_read($socket,2048)) { echo $out; } socket_close($socket); ?>
