先建一个socket类：
Socket.class.php代码如下：
<?php
namespace Org\Util;

class Socket {
protected $_config = array(
'persistent' => false,
'host' => '127.0.0.1',
'protocol' => 'tcp',
'port' => 10005,
'timeout' => 30
);
public $config = array();
public $connection = null;
public $socket = null;
public $connected = false;
public $error = array();
public function __construct($config = array()) {
$this->config = array_merge($this->_config,$config);
if (!is_numeric($this->config['protocol'])) {
$this->config['protocol'] = getprotobyname($this->config['protocol']);
}
}
/** 创建socket,成功返回true，失败返回false */
public function createSocket(){
$bRes = false;
if(!$this->socket){
$this->socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
$bRes = true;
}else{
$bRes = false;
}
return $bRes;
}
public function connect() {
if ($this->connection != null) {
$this->disconnect();
}
if ($this->config['persistent'] == true) {
$tmp = null;
$this->connection = @pfsockopen($this->config['host'], $this->config['port'], $errNum, $errStr, $this->config['timeout']);
} else {
$this->connection = fsockopen($this->config['host'], $this->config['port'], $errNum, $errStr, $this->config['timeout']);
stream_set_timeout( $this->connection , 5 ) ;
}
if (!empty($errNum) || !empty($errStr)) {
$this->error($errStr, $errNum);
}
$this->connected = is_resource($this->connection);
return $this->connected;
}
public function error() {
}
public function write($data) {
if (!$this->connected) {
if (!$this->connect()) {
return false;
}
}
return fwrite($this->connection, $data, strlen($data));
}
public function read($length=1024) {
if (!$this->connected) {
if (!$this->connect()) {
return false;
}
}
if (!feof($this->connection)) {
$res=fread($this->connection, $length);
$status = stream_get_meta_data( $this->connection ) ;
//读取数据超时
if( $status['timed_out'] )
return false;
return $res;
} else {
return false;
}
}
public function disconnect() {
if (!is_resource($this->connection)) {
$this->connected = false;
return true;
}
$this->connected = !fclose($this->connection);
if (!$this->connected) {
$this->connection = null;
}
return !$this->connected;
}
public function __destruct() {
$this->disconnect();
}
}
将扩展类放在ORG类库包下面。这里我是放在了..\ThinkPHP\Library\Org\Util下面了
方法中调用：
import('ORG.Util.Socket');// 导入socket类
$socket = new \Org\Util\Socket();//实例化
$result = $socket->connect();//连接
$data = "我是客户端，我要发数据给服务端";
$socket->write($data);
$read = $socket->read();//$read 是服务端还回的数据
$socket->disconnect();//关闭连接
