PHP uses memcached simple example to share

In many occasions, we will hear the name memcached, but many students just heard, and did not use or actually understand, only know it is a very good stuff. Here is a brief introduction, memcached is an efficient and fast distributed memory object caching system, mainly used to speed up web dynamic applications. Today we'll start with a simple discussion of the use of memcached.

-->

1. Add Expansion pack

The code is as follows:
Php_memcache.dll

2. Add in PHP.ini

The code is as follows:
Extension=php_memcache.dll

3. The procedure

The code is as follows:
<?php
Create a Mem object instance
$mem =new Memcache;
if (! $mem->connect ("10.18.110.213", 11211)) {
Die (' Connection failed! ');
}
Increase
1. Add a String
/* IF ($mem->set (' Key1 ', "Beijing", memcache_compressed,60)) {
echo ' Add OK ';
}*/
2. Add Value
/* IF ($mem->set (' Key1 ', 100,memcache_compressed,60)) {
echo ' Add OK ';
}*/
3. Adding an array
In addition to the array is, as required. Want the serial number into,
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 ', $dog 1,memcache_compressed,60)) {
Echo ' Add object OK ';
}*/
5. Add a null Boolean value
/* IF ($mem->set (' Key1 ', false,memcache_compressed,60)) {
Echo ' Add boolean ok ';
}*/
6. The resource type is put in.
/* $con =mysql_connect ("127.0.0.1", "root", "root");
if (! $con) {
Die (' Connection database failed ');
}
Var_dump ($con);
echo "<br/>";
if ($mem->set (' Key1 ', $con, memcache_compressed,60)) {
Echo ' Add resource ok ';
}*/
Inquire
$val = $mem->get (' Key1 ');
Modify
You can use the Replace
if ($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 ';
}

Above is the introduction of the use of memcache in PHP, I hope you can help.
