上一篇文章给大家介绍了memcached的安装以及简单的命令。这里给大家介绍php如何结合memcached。配置其实很简单的就几步操作。

1. 先安装php的memcache扩展，相信大家对php的扩展模块安装不会陌生。

首先可以去pecl.php.net    官网下载安装包，我这里下载的2.2.5版本
# 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
# make && make installl安装完后会有类似这样的提示：
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20130626/

然后修改php.ini，把extension_dir = "./" 修改为
extension_dir = "/usr/local/php/extensions"并添加一行
extension="memcache.so"

然后创建目录 mkdir /usr/local/php/extensions

将no-debug-non-zts-20130626/目录下的memcache.so移到/usr/local/php/extensions/目录下

/usr/local/php/bin/php -m |grepmemcache 可以检验扩展模块是否添加成功。

2. php脚本测试

首先写一个测试的php脚本

vim test.php 

#############

$mem = new Memcache;

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

//保存数据

$mem->set('key1', 'This is first value', 0, 60);

$val = $mem->get('key1');

echo "Get key1 value: " . $val ."
";

//替换数据

$mem->replace('key1', 'This is replace value', 0, 60);

$val = $mem->get('key1');

echo "Get key1 value: " . $val . "
";

//保存数组数据

$arr = array('aaa', 'bbb', 'ccc', 'ddd');

$mem->set('key2', $arr, 0, 60);

$val2 = $mem->get('key2');

echo "Get key2 value: ";

print_r($val2);

echo "
";

//删除数据

$mem->delete('key1');

$val = $mem->get('key1');

echo "Get key1 value: " . $val . "
";

//清除所有数据

$mem->flush();

$val2 = $mem->get('key2');

echo "Get key2 value: ";

print_r($val2);

echo "
";

//关闭连接

$mem->close();

?>

然后执行命令：/usr/local/php/bin/php test.php
看看能否得到如下内容：

Get key1 value: This is first value
Get key1 value: This is replace value
Get key2 value: Array

(

    [0] => aaa

    [1] => bbb

    [2] => ccc

    [3] => ddd

)

Get key1 value:
Get key2 value:

如果得到此内容说明结合成功。
