php数组遍历类与用法

php数组遍如何使用？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,下面小编就为大家带来相关的介绍，需要的朋友就来一聚教程网参考一下吧！

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：

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.'
';
        }
      }
      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[vv][b]=b

array[vv][l]=c

array[vv][xx][0]=e

array[vv][xx][1]=g
