我有一个带有构造的class.php
<?php
class Fruit {
public $name;
public $color;
function __construct($name, $color) {
$this->name = $name;
$this->color = $color;
}
function get_name() {
return $this->name;
}
function get_color() {
return $this->color;
}
}
在其他文件中我想打电话给我时 以这种方式工作:
$apple1 = new Fruit("Apple", "red");
$apple2 = new Fruit("Apple", "yellow");
但我需要打电话:
$apple1 = new Fruit($name1, $color1);
$apple2 = new Fruit($name2, $color2);
$name1='Apple';
$color1= get_user_meta($user_id, 'color', true);
$name2='Apple';
$color2='yellow';
所有这些看起来像未定义。我看到这不是正确的方法,但是我该怎么办? 非常感谢!
You can call a
__construct
by variables but for that you must specify them before you instantiate new object.将您的代码更改为
