非静态方法 ..... 不应静态调用
我最近更新了 PHP 5.4，但收到关于静态和非静态代码的错误.
I have recently done an update to PHP 5.4, and I get an error about static and non-static code.
这是错误:
PHP Strict Standards: Non-static method VTimer::get()
should not be called statically in /home/jaco/public_html/include/function_smarty.php on line 371
这是第 371 行:
$timer = VTimer::get($options['magic']);
希望有人能帮忙.
推荐答案
这意味着它应该被称为:
That means it should be called like:
$timer = (new VTimer)->get($options['magic']);
static 和 non-static 的区别在于第一个不需要初始化，所以你可以调用 classname 然后追加:: 并立即调用该方法.像这样:
The difference between static and non-static is that the first one doesn't need initialization so you can call the classname then append :: to it and call the method immediately.
Like so:
ClassName::method();
如果方法不是静态的，你需要像这样初始化它:
and if the method is not static you need to initialize it like so:
$var = new ClassName();
$var->method();
但是，在 PHP 5.4 中，您可以使用以下语法作为简写:
However, in PHP 5.4 you can use this syntax instead as a shorthand:
(new ClassName)->method();
