Hello Readers,

In this post I want to explain the Memcached with PHP.

Memcahced is open source distributed memory object caching system it helps you to speeding up the dynamic web applications by reducing database server load.

The Memcached is very helpul to manage blog related and the sites who acquires high traffics.

Memcached steps which are use in PHP code:

1 Start the memcached program so there is a server that actually stores the key-value pairs.
2 Make a memcache object.
3 Store a value for a key.
4 Retrieve your key.

$memcache = new Memcache; //point2
$memcache->set($yourUniqueKey, $yourValue, false, 3600); //point3
//later:
$memcache->get($yourUniqueKey); //point4

The Memcached with PHP code:

First we make a database connection db.php.

db.php

$mysql_hostname = "localhost";
$mysql_user = "username";
$mysql_password = "password";
$mysql_database = "database";
$db = mysql_connect($mysql_hostname, $mysql_user, $mysql_password) ;
mysql_select_db($mysql_database, $db);

Then we make a index page index.php

index.php

include('db.php');
$memcache = new Memcache;
$memcache->connect('localhost', 11211) or die ("Could not connect");
$key = md5('List'); // Unique Words
$cache&_result = array();
$cache&_result = $memcache->get($key); // Memcached object 
if($cache_result)
{
// Second User Request
$demos_result=$cache_result;
}
else
{
// First User Request 
$v=mysql_query("select * from table_name order by id desc");
while($row=mysql_fetch_array($v))
$demos_result[]=$row; // Results storing in array
$memcache->set($key, $demos_result, MEMCACHE_COMPRESSED, 1100); 
// 1100 Seconds
}
// Result 
foreach($demos_result as $row)
{

    echo '<a href='.$row['link'].'>'.$row['title'].'</a>';

}
