最近用Swoole寫了一個聊天室 http://www.azcity.cn
下面發下聊天室的代碼
server.php
<?php
require_once("redisDb.php" ); //自己簡單些的redis類
require_once("rndChinaName.php" ); //用於隨機生成名字
class server{
private $redis;
private $randName;
public function __construct(){
$this->redis = new redisDb();
$this->randName = new rndChinaName();
$this->redis->flushAll();
echo "redis is connect";
}
public function getChar($num) // $num爲生成漢字的數量
{
$b = '';
for ($i=0; $i<$num; $i++) {
// 使用chr()函數拼接雙字節漢字，前一個chr()爲高位字節，後一個爲低位字節
$a = chr(mt_rand(0xB0,0xD0)).chr(mt_rand(0xA1, 0xF0));
// 轉碼
$b .= iconv('GB2312', 'UTF-8', $a);
}
return $b;
}
public function getName(){
return $this->randName->getName();
}
public function socket(){
