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
<?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";
?>
