memcached的使用

基本使用方法

<?php
/**
* Created by PhpStorm.
* User: raid
* Date: 2016/7/6
* Time: 12:03
*/

$m = new Memcached;
$arr = array(
array('127.0.0.1', 11211),
array('127.0.0.2', 11211),
);
$m->addServer('127.0.0.1', 11211);
print_r($m->getStats());
echo "<br/>";
print_r($m->getVersion());
echo "<br/>";

$data = array(
'key' => 'value',
'key2' => 'value2',
);
//$m->setMulti($data, 600);
$result = $m->getMulti(array('key', 'key2'));
$m->deleteMulti(array('key', 'key2'));
//print_r($result);
echo $m->get('key');

echo $m->getResultCode();
echo $m->getResultMessage();

//$m->add('mkey', 'mvalue', 600);
//$m->replace('mkey', 'mvalue2', 1);

//$m->flush();

//$m->set('num', 50, 600);

//$m->increment('num', 5);

$m->decrement('num', 5);

echo $m->get('num');

$m->flush();

封装类：
<?php

/**
* Created by PhpStorm.
* User: raid
* Date: 2016/7/6
* Time: 19:25
*/
class Mem {
//Memcached对象
private $m;
//对象类型
private $type = 'Memcached';
//缓存时间
private $time = 0;
//错误
private $error;
//是否开启调试模式
private $debug = 'true';

public function __construct() {
if (!class_exists($this->type)) {
$this->error = 'No '.$this->type;
return false;
} else {
$this->m = new $this->type;
}
}

public function addServer($arr) {
$this->m->addServers($arr);
}

public function s($key, $value = '', $time = NULL) {
$number = func_num_args();
if ($number == 1) {
//get操作
return $this->get($key);
} else if ($number >= 2) {
if ($value === NULL) {
//delete操作
$this->delete($key);
} else {
//set操作
$this->set($key, $value, $time);
}

}
}

private function set($key, $value, $time = NULL) {
if ($time === NULL) {
$time = $this->time;
}
$this->m->set($key, $value, $time);
if ($this->debug) {
if ($this->m->getResultCode() != 0) {
return false;
}
}
}

private function get($key) {
$ret = $this->m->get($key);
if ($this->debug) {
if ($this->m->getResultCode() != 0) {
return false;
}
}

return $ret;
}

/**
* 删除
* @param $key
*/
private function delete($key) {
$this->m->delete($key);
}

public function getError() {
if ($this->error) {
return $this->error;
} else {
return $this->m->getResultMessage();
}
}

public function d($debug) {
$this->debug = $debug;
}

}

封装类的使用：
<?php
/**
* Created by PhpStorm.
* User: raid
* Date: 2016/7/6
* Time: 19:06
*/

include 'Mem.class.php';

$m = new Mem();

$m->addServer(array(
array('127.0.0.1', 11211),
));

//$m->s('key', 'value', 1800);
//
//$m->s('key', NULL);
//echo $m->s('key');
//echo $m->getError();

$m->s('test', 'testvalue', 0);
echo $m->s('test');
echo "<br/>";
$m->s('test', NULL);
echo $m->s('test');
