使用类来对二维数组进行输出应该怎么做？

Question

<?php

类演示{

protected $name;

protected $age;

protected $wages;

公共函数 __construct($name,$age,$wages){

$this->name = $name;

$this- >age = $age;

$this->wages = $wages;

## }

public function show() {

return "员工的姓名是：{$this->name} 年龄：{$this->age} 工资：{$this->wages}";

}

}

## $obj = new demo('peter',24,5000);

echo $obj-> show();

    echo '
';

$arr = array(array('name'=>'jike ','年龄'=>18,'工资'=>'500'),

array('姓名'=>'吉克','年龄'=>18,'工资' =>'500'),);

foreach ($arr as $key => $value) {

if(is_array($value)){

foreach ($value as $key => $v) {

echo $key.'-'.$v.'
';

}

}

}

?>
