[php]对象遍历

对象遍历

foreach($对象名 as $key => $value){
//处理$key 和 $value 的本体。
//$key是对象的属性，$value是该属性的值
}

<?php

class A{
public $p1 = 1;
protected $p2 = 2;
private $p3 = 3;
static $p4 = 4;    //静态属性无法遍历
}

$obj1 = new A();
foreach($obj1 as $key => $value){
echo "属性$key: $value";
}
?>
//属性p1 : 1

<?php

class A{
public $p1 = 1;
protected $p2 = 2;
private $p3 = 3;
static $p4 = 4;    //静态属性无法遍历

function showAll(){
echo "属性$key: $value";
}
}

$obj1 = new A();
$obj1 -> showAll();
?>
//  属性p1 : 1
属性p2 : 2
属性p3 : 3
