php：面向对象之成员变量（数组）

php：面向对象之成员变量（数组）

一、PHP源码

 1 <?php 
 2 
 3     class DATA{
 4         public $dlt_data = "";
 5         
 6         // set value of $dlt_data by ARRAY
 7         function set_value($array_type)
 8         {
 9             $this->dlt_data = $array_type;
10         }
11     }
12     
13 
14     function display_data($DATA_type)
15     {
16         foreach($DATA_type->dlt_data as $k=>$v)
17         {
18             echo $k . " => " . $v . PHP_EOL;
19         }
20     }
21     
22     
23     $DATA_object = new DATA;
24     $array_laohu = array("book1"=>"gold", "book2"=>"wood", 3=>"water");
25     
26     $DATA_object->set_value($array_laohu);    
27     
28     //set value of '$DATA_object->dlt_data' by another way.
29     $DATA_object->dlt_data["book4"] = "earth";
30     
31     display_data($DATA_object);
32     
33 ?>
