PHP combined memcached

The previous article introduced the installation of memcached and the simple commands. Here we introduce how PHP combines memcached.

The configuration is actually very simple just a few steps.

1. First install php memcache extension, I believe you will not be unfamiliar with the expansion module installation of PHP.

First, you can go to pecl.php.net official website to download the installation package, I downloaded here 2.2.5 version
# tar Zxfmemcache-2.2.5.tgz
# CD memcache-2.2.5
#/usr/local/php/bin/phpize
#./configure--with-php-config=/usr/local/php/bin/php-config
# makes && make installl after installation there will be a hint like this:
Installing Shared extensions:/usr/local/php/lib/php/extensions/no-debug-non-zts-20130626/

Then modify the php.ini and change the Extension_dir = "./" revision to
Extension_dir = "/usr/local/php/extensions" and adds a row
extension= "Memcache.so"

Then create the directory mkdir /usr/local/php/extensions

move memcache.so under the no-debug-non-zts-20130626/directory to the /usr/local/php/extensions/directory

/usr/local/php/bin/php-m |grepmemcache can verify that the extension was added successfully.

2. PHP Script test

First, write a test php script

Vim test.php content is as follows:

<?php

$mem = new Memcache;

$mem->connect ("localhost", 11211);

Save data

$mem->set (' key1 ', ' This is first value ', 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>";

Saving array data

$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 ();

?>

Then execute the command:/usr/local/php/bin/php test.php
See if you can get the following:

Get Key1 Value:this is first value<br>get key1 value:this is replace Value<br>get key2 Value:array

(

[0] = AAA

[1] = BBB

[2] = = CCC

[3] = DDD

)

<br>get key1 Value: <br>get key2 value: <br>

If you get this content the description is combined successfully .
