PHP using Memcache caching technology to introduce a simple

Connecting to a database

The code is as follows	Copy Code
$memcache _obj = Memcache_connect ("localhost", 11211); Memcache_add ($memcache _obj, ' var_key ', ' Test variable ', false, 30); $memcache _obj->add (' Var_key ', ' Test variable ', false, 30);

Instance 1

The code is as follows

Copy Code

<?php Connection $mem = new Memcache; $mem->connect ("127.0.0.1″, 11211) or Die" ("Could not Connect"); Display version $version = $mem->getversion (); echo "Memcached Server version:". $version. " <br> "; Save data $mem->set (' key1′, ' This is ', ', 0, 60); $val = $mem->get (' key1′); echo "Get Key1 Value:". $val. " <br> "; Replace data $mem->replace (' key1′, ' This is replace value ', 0, 60); $val = $mem->get (' key1′); echo "Get Key1 Value:". $val. "<br>"; Save Array $arr = Array (' AAA ', ' BBB ', ' CCC ', ' ddd '); $mem->set (' key2′, $arr, 0, 60); $val 2 = $mem->get (' key2′); echo "Get Key2 value:"; Print_r ($val 2); echo "<br>"; Delete data $mem->delete (' key1′); $val = $mem->get (' key1′); echo "Get Key1 Value:". $val. "<br>"; Clear All data $mem->flush (); $val 2 = $mem->get (' key2′); echo "Get Key2 value:"; Print_r ($val 2); echo "<br>"; Close connection $mem->close (); ?>

The Memcache function library is in the PECL (PHP Extension Community Library), the main role is to build large capacity of the memory data temporary storage area

, in the distributed time the role manifests is very obvious, the network marketing training otherwise does not suggest uses.
