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
