PHP uses memcached simple example to share

This article simply to the Code farmers introduce memcached. Memcached is an efficient and fast distributed memory object caching system that is primarily used to accelerate web dynamic applications. Today, I and yard farmers to briefly discuss the use of memcached.

1. Add memcached expansion pack

php_memcache.dll

2. Add memcached extension to php.ini

extension=php_memcache.dll

3. Procedures

<?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. Hope the serial number is put in,//serialize<=>unserialize, if necessary, can also json_encode <=> json_decode    $arr=Array("BJ", ' TJ '); if($mem->set (' Key1 ',$arr, memcache_compressed, Time() +31*3600*24)){        Echo' Add array ok99111 '; }    //4. 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 ', $dog 1,memcache_compressed,60)) {echo ' Add object OK '; }*/    //5. Adding a null Boolean value/*if ($mem->set (' Key1 ', false,memcache_compressed,60)) {echo ' adds Boolean ok '; }*/    //6. Type the resource into./*$con =mysql_connect ("127.0.0.1", "root", "root");    if (! $con) {die (' failed to connect to database ');    } var_dump ($con);    echo "<br/>";    if ($mem->set (' Key1 ', $con, memcache_compressed,60)) {echo ' Add resource ok '; }*/    //Enquiry    $val=$mem->get (' Key1 ');//Modify//can use replace    if($mem->replace ("Key11", ' Hello ', memcache_compressed,60)){        Echo' Replace OK '; }Else{        Echo' Replace no OK '; }    //Delete    Echo"<br/>"; if($mem->delete (' Key14 ')){        Echo' Key14 Delete '; }Else{        Echo' KEY14 does not exist '; }
