30个php操作redis常用方法代码例子
redis的操作很多的,以前看到一个比较全的博客,但是现在找不到了。查个东西搜半天,下面整理一下php处理redis的例子,个人觉得常用一些例子。下面的例子都是基于php-redis这个扩展的。
1,connect
描述:实例连接到一个Redis.
参数:host: string,port: int
返回值:BOOL 成功返回:TRUE;失败返回:FALSE
示例:
复制代码 代码如下:
<"codetitle">复制代码 代码如下:
<"11111111111");
var_dump($result); //结果:bool(true)
"codetitle">复制代码 代码如下:
<"11111111111"
"codetitle">复制代码 代码如下:
<"1111111111111");
echo $redis->get('test'); //结果:1111111111111
$redis->delete('test');
var_dump($redis->get('test')); //结果:bool(false)
"codetitle">复制代码 代码如下:
<"1111111111111");
$redis->setnx('test',"22222222");
echo $redis->get('test'); //结果:1111111111111
$redis->delete('test');
$redis->setnx('test',"22222222");
echo $redis->get('test'); //结果:22222222
"codetitle">复制代码 代码如下:
<"1111111111111");
var_dump($redis->exists('test')); //结果:bool(true)
"codetitle">复制代码 代码如下:
<"123");
var_dump($redis->incr("test")); //结果:int(124)
var_dump($redis->incr("test")); //结果:int(125)
"codetitle">复制代码 代码如下:
<"123");
var_dump($redis->decr("test")); //结果:int(122)
var_dump($redis->decr("test")); //结果:int(121)
"codetitle">复制代码 代码如下:
<"1");
$redis->set('test2',"2");
$result = $redis->getMultiple(array('test1','test2'));
print_r($result); //结果:Array ( [0] => 1 [1] => 2 )
"codetitle">复制代码 代码如下:
<"test","111")); //结果:int(1)
var_dump($redis->lpush("test","222")); //结果:int(2)
"codetitle">复制代码 代码如下:
<"test","111")); //结果:int(1)
var_dump($redis->lpush("test","222")); //结果:int(2)
var_dump($redis->rpush("test","333")); //结果:int(3)
var_dump($redis->rpush("test","444")); //结果:int(4)
"codetitle">复制代码 代码如下:
