php：面向对象之成员变量（数组）

 

 

 

 

一、PHP源码

 

 

<?php 

    class DATA{
        public $dlt_data = "";
        
        // set value of $dlt_data by ARRAY
        function set_array_value($array_type)
        {
            $this->dlt_data = $array_type;
        }
        
        // set value of '$DATA->dlt_data' by key and value.
        function set_key_value($key, $value)
        {
            $this->dlt_data[$key]=$value;
        }
    }
    

    function display_data($DATA_type)
    {
        foreach($DATA_type->dlt_data as $k=>$v)
        {
            echo $k . " => " . $v . PHP_EOL;
        }
    }
    
    
    $DATA_object = new DATA;
    $array_laohu = array("elem1"=>"gold", "elem2"=>"wood", 3=>"water");
    
    $DATA_object->set_array_value($array_laohu);
    $DATA_object->set_key_value("elem5", "earth");
    
    //set value of '$DATA_object->dlt_data' by another way.
    $DATA_object->dlt_data["elem4"] = "fire";
    
    display_data($DATA_object);
    
?>
