Zend Framework里Zend_Config类解析

只讨论对ini的解析方法

例如
[Ini]
File=layout
layout.head.Module=Default
layout.head.Controller=Index
layout.head.Action=Head
layout.head.Option=
[New]
File=layout
head.Module=Default
head.Controller=Index
head.Action=Index

可以解析为：

$array[Ini][File]=layout

$array[Ini][layout][head][Module]=Default

$array[Ini][layout][head][Controller]=Index

等，这里面主要用到了一个递归思想，但是也很简单，算不上难

private function _LoadFile($file){if(null==$file){require "Exception.php";throw new PandarException("config file is not provide!");}$ini_array = parse_ini_file($file,ture);$this->_parasFile($ini_array);}/* * paras the file to array */private function _parasFile($ini_array){$configs=array();$config=array();foreach($ini_array as $key=>$value){foreach($value as $subkey=>$subvalue){$configs=array_merge_recursive($configs,$this->_processKey($config,$subkey,$subvalue));}$this->_ini[$key]=$configs;$configs=array();}}/* * recursion paras the array key to many dimensions array */private function _processKey($config,$key,$value){if (strpos($key, $this->_configSeparator) !== false) {$pieces=explode($this->_configSeparator,$key,2); if (strlen($pieces[0]) && strlen($pieces[1])) { //$config[$pieces[0]]=array(); $config[$pieces[0]]=$this->_processKey($config[$pieces[0]],$pieces[1],$value); }}else{$config[$key]=$value;}return $config;}

上面算是简化出来的代码，在_processKey($config,$key,$value)函数不断测试ini文件每一条记录的左部是否还存在分隔符‘.’，存在则递归，否则赋值，最后利用array_merge_recursive函数将数组进行拼接
