DB 配置

在使用 DB 相关函数的时候，需要配置数据库相关信息。一般存放在文件中。

新建配置文件 conf.php：

<?php

return array (
	"cache" => array (
		"enable" => true,
		"type" => "xcache",
		"memcached" => array (
			"host" => "localhost",
			"port" => "11211",
			"cachepre" => "bbs_",
		),
		"redis" => array (
			"host" => "localhost",
			"port" => "6379",
			"cachepre" => "bbs_",
		),
		"xcache" => array (
			"cachepre" => "bbs_",
		),
		"yac" => array (
			"cachepre" => "bbs_",
		),
		"apc" => array (
			"cachepre" => "bbs_",
		),
		"mysql" => array (
			"cachepre" => "bbs_",
		),
	),
);

?>

如果用 MySQL 来存储数据，得自己建立表：

# 缓存表，用来保存临时数据。
DROP TABLE IF EXISTS bbs_cache;
CREATE TABLE bbs_cache (
  k char(32) NOT NULL default "",
  v mediumtext NOT NULL,
  expiry int(11) unsigned NOT NULL default "0",		# 过期时间
  PRIMARY KEY(k)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_general_ci;

include 配置文件：

<?php

$conf = include "./conf.php";
include "./xiunophp/xiunophp.php";

// 下面就可以使用 cache_xxx() 系列函数了，具体请参看文档。
cache_set("key1", "value1");
cache_get("key1");

?>
