Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP

<?phpclass Car{    var $color = "add";    function Car($color="green") {        $this->color = $color;    }    function what_color() {        return $this->color;    }}$car = new Car;echo $car->what_color(),"<br>over";?>

PHP版本号

php 7.0.10

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

<?phpclass 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";?>
