[英]Referencing a static class from within another class
I have a class: 我有一堂课:
class Site
{
public static $url;
}
I assign a value to it: Site::$url = "whatever"; 我给它赋一个值:Site :: $ url =“ whatever”;
I have another class: 我还有另一堂课:
class Something
{
public function __Construct()
{
echo Site::$url; // does not seem to have scope?
}
}
How do I give scope to the Something class. 如何将范围赋予Something类。
It should work as you've written it above: 如您在上面所写,它应该可以工作:
class Site {
public static $url;
}
class Something {
public function __construct() {
echo Site::$url;
}
}
Site::$url = 'whatever';
new Something(); // prints 'whatever'
If that's not working, it's likely because the classes are being declared in two different namespaces. 如果这不起作用,则可能是因为在两个不同的命名空间中声明了类。
