php读取配置文件信息

简单的实现源码：

<?php

class Settings{

public $_settings = array();

public function get($var){

$var = explode('.',$var);

$result = $this->_settings;

foreach($var as $key){

if(!isset($result[$key])){return false;}

$result = $result[$key];

}

return $result;

}

public function loadErr(){

trigger_error('Not yet implemented',E_USER_ERROR);

}

}

Class Settings_INI Extends Settings {

function load ($file) {

if (file_exists($file) == false) { return false; }

$this->_settings = parse_ini_file ($file, true);

}

}

/**

读取INI文件,主要用到parser_ini_file函数,该函数返回一个数组,如第二个参数为true时则返回多维数组

ini例子:

[db]

name = 'host=192.168.1.241'

ip = 'localhost'

host = 'port=5432'

dbname = 'dbname=hjhome'

login = 'user=hj password=hj'

*/

$settings = new Settings_INI;

$settings->load('config.ini');

$html = '<table border=1>';

$html.= '<tr><th>item</th><th>content</th>';

$html.= '<tr><td>' . 'name' . '</td><td>' . $settings->get('db.name') . '</td></tr>';

$html.= '<tr><td>' . 'ip' . '</td><td>' . $settings->get('db.ip') . '</td></tr>';

$html.= '<tr><td>' . 'host' . '</td><td>' . $settings->get('db.host') . '</td></tr>';

$html.= '<tr><td>' . 'dbname' . '</td><td>' . $settings->get('db.dbname') . '</td></tr>';

$html.= '<tr><td>' . 'login' . '</td><td>' . $settings->get('db.login') . '</td></tr>';

$html.= '</table>';

echo $html;
