<?php class 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
<?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"; ?>
