PhalconConfig 是一个用于将各种格式的配置文件读取到PHP对象的组件（使用适配器）。
可用的适配器有:
下面的例子展示如何将本地数组导入 PhalconConfig 对象。此选项提供了最好的性能，因为在这个请求中没有读取文件。
<?php
use PhalconConfig;
$settings = array(
"database" => array(
"adapter" => "Mysql",
"host" => "localhost",
"username" => "scott",
"password" => "cheetah",
"dbname" => "test_db"
),
"app" => array(
"controllersDir" => "../app/controllers/",
"modelsDir" => "../app/models/",
"viewsDir" => "../app/views/"
),
"mysetting" => "the-value"
);
$config = new Config($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，你可以在另一个文件保存数组，然后读入它。
<?php
use PhalconConfig;
require "config/config.php";
$config = new Config($settings);
INI文件是存储设置的常用方法。PhalconConfig 采用优化的PHP函数parse_ini_file读取这些文件。为方便访问，文件部分解析成子设置。
[database]
adapter = Mysql
host = localhost
username = scott
password = cheetah
dbname = test_db
[phalcon]
controllersDir = "../app/controllers/"
modelsDir = "../app/models/"
viewsDir = "../app/views/"
[models]
metadata.adapter = "Memory"
你可以阅读如下所示的文件:
<?php
use PhalconConfigAdapterIni as ConfigIni;
$config = new ConfigIni("path/config.ini");
echo $config->phalcon->controllersDir, "n";
echo $config->database->username, "n";
echo $config->models->metadata->adapter, "n";
PhalconConfig 允许合并配置对象到另一个:
<?php
use PhalconConfig;
$config = new Config(
array(
'database' => array(
'host' => 'localhost',
'dbname' => 'test_db'
),
'debug' => 1
)
);
$config2 = new Config(
array(
'database' => array(
'dbname' => 'production_db',
'username' => 'scott',
'password' => 'secret'
),
'logging' => 1
)
);
$config->merge($config2);
print_r($config);
上面的代码会产生以下内容:
PhalconConfig Object
(
[database] => PhalconConfig Object
(
[host] => localhost
[dbname] => production_db
[username] => scott
[password] => secret
)
[debug] => 1
[logging] => 1
)
