php数组遍历类与用法示例
这篇文章主要介绍了php数组遍历类与用法,结合实例形式分析了php基于面向对象的数组遍历、读取操作封装与使用技巧,需要的朋友可以参考下。
本文实例讲述了php数组遍历类与用法，分享给大家供大家参考，具体如下：
- <?php
- class scanArray{
- public $arr;
- public $where;
- private $str;
- public function scan($arr,$where="array"){
- $this->arr = $arr;
- $this->where = $where;
- foreach($this->arr as $k=>$v){
- if(is_array($v)){
- $this->where = ($this->where)."[{$k}]";
- $this->scan($v,$this->where);
- }else{
- $this->str .= $this->where."[{$k}]=".$v.'<br />';
- }
- }
- return $this->str;
- }
- function __destruct(){
- unset($this->arr);
- unset($this->where);
- }
- }
- $a = array('g'=>"a",'vv'=>array("b"=>"b","l"=>"c","xx"=>array("e","g")));
- $ah = new scanArray();
- $b = $ah->scan($a);
- echo $b;
运行结果：
- array[g]=a
- array[vv][b]=b
- array[vv][l]=c
- array[vv][xx][0]=e
- array[vv][xx][1]=g
