本文实例讲述了PHP实现操作redis的封装类。分享给大家供大家参考，具体如下：
null,// 只支持一台 Master 'slave'=>array(),// 可以有多台 Slave ); public function __construct($isUseCluster=false){ $this->_isUseCluster = $isUseCluster; } public function connect($config=array('host'=>'127.0.0.1','port'=>6379), $isMaster=true){ // default port if(!isset($config['port'])){ $config['port'] = 6379; } // 设置 Master 连接 if($isMaster){ $this->_linkHandle['master'] = new Redis(); $ret = $this->_linkHandle['master']->pconnect($config['host'],$config['port']); }else{ // 多个 Slave 连接 $this->_linkHandle['slave'][$this->_sn] = new Redis(); $ret = $this->_linkHandle['slave'][$this->_sn]->pconnect($config['host'],$config['port']); ++$this->_sn; } return $ret; } public function close($flag=2){ switch($flag){ // 关闭 Master case 0: $this->getRedis()->close(); break; // 关闭 Slave case 1: for($i=0; $i<$this->_sn; ++$i){ $this->_linkHandle['slave'][$i]->close(); } break; // 关闭所有 case 1: $this->getRedis()->close(); for($i=0; $i<$this->_sn; ++$i){ $this->_linkHandle['slave'][$i]->close(); } break; } return true; } public function getRedis($isMaster=true,$slaveOne=true){ // 只返回 Master if($isMaster){ return $this->_linkHandle['master']; }else{ return $slaveOne ? $this->_getSlaveRedis() : $this->_linkHandle['slave']; } } public function set($key, $value, $expire=0){ // 永不超时 if($expire == 0){ $ret = $this->getRedis()->set($key, $value); }else{ $ret = $this->getRedis()->setex($key, $expire, $value); } return $ret; } public function get($key){ // 是否一次取多个值 $func = is_array($key) ? 'mGet' : 'get'; // 没有使用M/S if(! $this->_isUseCluster){ return $this->getRedis()->{$func}($key); } // 使用了 M/S return $this->_getSlaveRedis()->{$func}($key); } public function setnx($key, $value){ return $this->getRedis()->setnx($key, $value); } public function remove($key){ // $key => "key1" array('key1','key2') return $this->getRedis()->delete($key); } public function incr($key,$default=1){ if($default == 1){ return $this->getRedis()->incr($key); }else{ return $this->getRedis()->incrBy($key, $default); } } public function decr($key,$default=1){ if($default == 1){ return $this->getRedis()->decr($key); }else{ return $this->getRedis()->decrBy($key, $default); } } public function clear(){ return $this->getRedis()->flushDB(); } private function _getSlaveRedis(){ // 就一台 Slave 机直接返回 if($this->_sn <= 1){ return $this->_linkHandle['slave'][0]; } // 随机 Hash 得到 Slave 的句柄 $hash = $this->_hashId(mt_rand(), $this->_sn); return $this->_linkHandle['slave'][$hash]; } private function _hashId($id,$m=10) { //把字符串K转换为 0～m-1 之间的一个值作为对应记录的散列地址 $k = md5($id); $l = strlen($k); $b = bin2hex($k); $h = 0; for($i=0;$i<$l;$i++) { //相加模式HASH $h += substr($b,$i*2,2); } $hash = ($h*1)%$m; return $hash; } public function lpush($key,$value){ return $this->getRedis()->lpush($key,$value); } public function lpop($key){ return $this->getRedis()->lpop($key); } public function lrange($key,$start,$end){ return $this->getRedis()->lrange($key,$start,$end); } public function hset($name,$key,$value){ if(is_array($value)){ return $this->getRedis()->hset($name,$key,serialize($value)); } return $this->getRedis()->hset($name,$key,$value); } public function hget($name,$key = null,$serialize=true){ if($key){ $row = $this->getRedis()->hget($name,$key); if($row && $serialize){ unserialize($row); } return $row; } return $this->getRedis()->hgetAll($name); } public function hdel($name,$key = null){ if($key){ return $this->getRedis()->hdel($name,$key); } return $this->getRedis()->hdel($name); } public function multi(){ return $this->getRedis()->multi(); } public function exec(){ return $this->getRedis()->exec(); } }// End Class // ================= TEST DEMO ================= // 只有一台 Redis 的应用 $redis = new RedisCluster(); $redis->connect(array('host'=>'127.0.0.1','port'=>6379)); / / // var_dump($redis->get('id')); 希望本文所述对大家PHP程序设计有所帮助。
