所报错误

Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; Car has a deprecated constructor in E:\phpStorm\firstPhp\test.php on line 8

解决方式

查阅资料，发现php7.0之后将不再支持与类名相同的构造方法，构造方法统一使用 __construct()。

改正后代码

?

<?php

class Car

{

    public $color = "add";

    function __construct($color="green") {   //注意是双下划线

        $this->color = $color;

    }

    public function what_color() {

        return $this->color;

    }

}

 

$car = new Car("red");

echo $car->what_color(),"<br>over";

?>
