Accelerated access to Redis and membercached

1.redis

Redis is fully open source free, complies with BSD protocol, advanced Key-value persistent products. It is commonly referred to as a data structure server, because the value can be a string (string), a hash (MAP), a list, a collection (sets), and an ordered set (sorted sets), and other types

Installing Redis

$ wget http://download.redis.io/releases/redis-2.8.17.tar.gz$ tar xzf redis-2.8.17.tar. gz$ cd Redis-2.8.17$ Make

Using Redis with PHP

<?PHP/*get the database name from the platform*/$dbname= ""; /*taking host,port,user,pwd from environment variables*/$host= ' ';$port= ' ';$user= ' ';$pwd= ' '; Try {    /*After the connection is established, auth validation is required before the collection operation*/    $redis=NewRedis (); $ret=$redis->connect ($host,$port); if($ret===false) {     die($redis-GetLastError ()); }      $ret=$redis->auth ($user. "-" .$pwd. "-" .$dbname); if($ret===false) {     die($redis-GetLastError ()); }      /*Next, you can operate the library, please refer to the Phpredis official documentation for details.*/    $redis-flushdb (); $ret=$redis->set ("Key", "value"); if($ret===false) {     die($redis-GetLastError ()); } Else {     Echo"OK".$redis->get ("Key"); }  } Catch(redisexception$e) {     die("Uncaught exception".$e-getMessage ());}?>

2.membercached

Installing the Linux membercached

PHP using membercached

<?PHP//creating an instance of a Mem object    $mem=NewMemcache; if(!$mem->connect ("10.18.110.213", 11211)){         die(' Connection failed! ')); }    //add a//1. Add a String/*if ($mem->set (' Key1 ', "Beijing", memcache_compressed,60)) {echo ' Add OK '; }*/        //2. Add a value/*if ($mem->set (' Key1 ', 100,memcache_compressed,60)) {echo ' Add OK '; }*/    //3. Add an array//In the Add array is, as needed.

Adding Objects/*class dog{public $name;        Public $age;            Public function __construct ($name, $age) {$this->name= $name;        $this->age= $age;    }} $dog 1=new dog (' Puppy ', 50);    if ($mem->set (' Key1 ', $dog 1,memcache_compressed,60)) {echo ' Add object OK '; }*/    //5.
