【www.bbyears.com--php常用代码】
一、server.php服务端：
代码如下error_reporting(E_ALL);
set_time_limit(0);
ob_implicit_flush();
//本地IP
$address='localhost';
//设置用111端口进行通信
$port= 111;
//创建SOCKET
if(($sock= socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) < 0) {
echo"socket创建失败原因 ". socket_strerror($sock) ."\n";
}
if(($ret= socket_bind($sock,$address,$port)) < 0) {
echo"创建套接字失败原因 ". socket_strerror($ret) ."\n";
}
//监听
if(($ret= socket_listen($sock, 5)) < 0) {
echo"监听失败原因 ". socket_strerror($ret) ."\n";
}
do{
//接收命令
if(($msgsock= @socket_accept($sock)) < 0) {
echo"命令接收失败原因: ". socket_strerror($msgsock) ."\n";
break;
}
$msg="\nPHP Test Server. \n"."用quit,shutdown,sun...等命令测试.\n";
@socket_write($msgsock,$msg,strlen($msg));
do{
if(false === ($buf= @socket_read($msgsock, 2048, PHP_NORMAL_READ))) {
echo"socket_read() failed: reason: ". socket_strerror($ret) ."\n";
break2;
}
if(!$buf= trim($buf)) {
continue;
}
if($buf=='quit') {
break;
}
if($buf=='shutdown') {
socket_close($msgsock);
break2;
}
if($buf=='sun') {
echo'what are you doing?';
}
$talkback="Backinformation : '$buf'.\n";
socket_write($msgsock,$talkback,strlen($talkback));
echo"$buf\n";
}while(true);
socket_close($msgsock);
}while(true);
socket_close($sock);
?>
二、client.php客户端:
代码如下error_reporting(E_ALL);
//端口111
$service_port= 111;
//本地
$address='localhost';
//创建 TCP/IP socket
$socket= socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if($socket< 0) {
echo"socket创建失败原因: ". socket_strerror($socket) ."\n";
}else{
echo"OK，HE HE.\n";
}
$result= socket_connect($socket,$address,$service_port);
if($result< 0) {
echo"SOCKET连接失败原因: ($result) ". socket_strerror($result) ."\n";
}else{
echo"OK.\n";
}
//发送命令
$in="HEAD / HTTP/1.1\r\n";
$in.="Connection: Close\r\n\r\n";
$out='';
echo"Send Command..........";
$in="sun\n";
socket_write($socket,$in,strlen($in));
echo"OK.\n";
echo"Reading Backinformatin:\n\n";
while($out= socket_read($socket, 2048)) {
echo$out;
}
echo"Close socket........";
socket_close($socket);
echo"OK,He He.\n\n";
?>
这两段代码是简单介绍用PHP实现客户端和服务端的通信
具体操作,在DOS下用PHP命令打开SERVER,处于监听状态..
再打开一个DOS窗口,用PHP命令打开CLIENT,会得到服务端的回应....
