Reading Configuration¶Phalcon\Config 使用相应的适配器读取配置文件,转换为面像对象的方式进行操作配置文件。 File Adapters¶可用的适配器:
原生数组¶下面的示例演示了如何把原生PHP数组转化为 Phalcon\Config 对象。下面的示例提供了最佳性能,因为在此请求期间,未发生文件读取。 <?php
$settings = array(
"database" => array(
"adapter" => "Mysql",
"host" => "localhost",
"username" => "scott",
"password" => "cheetah",
"name" => "test_db",
),
"app" => array(
"controllersDir" => "../app/controllers/",
"modelsDir" => "../app/models/",
"viewsDir" => "../app/views/",
),
"mysetting" => "the-value"
);
$config = new \Phalcon\Config($settings);
echo $config->app->controllersDir, "\n";
echo $config->database->username, "\n";
echo $config->mysetting, "\n";
如果你想更好的组织你的项目结构,你可以把数组保存到一个单独的文件中,然后读取它。 <?php
require "config/config.php";
$config = new \Phalcon\Config($settings);
读取INI文件¶INI文件是一种常见的方式来存储设置。Phalcon\Config 使用优化的PHP函数parse_ini_file读取这些文件。INI文件中的sections部分被解析成子设定,以方便使用。 [database]
adapter = Mysql
host = localhost
username = scott
password = cheetah
name = test_db
[phalcon]
controllersDir = "../app/controllers/"
modelsDir = "../app/models/"
viewsDir = "../app/views/"
[models]
metadata.adapter = "Memory"
你可以按以下方式读取配件文件: <?php
$config = new \Phalcon\Config\Adapter\Ini("path/config.ini");
echo $config->phalcon->controllersDir, "\n";
echo $config->database->username, "\n";
echo $config->models->metadata->adapter, "\n";
