Is it wrong to use OOP for "help analysis"? An OOP error in PHP ~

function:Returns data based on the specified ID (URL)
Code:

Usage:

$arr = Urlpath::goods (1024x768);p Rint_arr ($arr);

In addition:There is an error at the beginning, can't write like this? procted $db = $GLOBALS [' db '];


question:
One: I want to use Urlpath::goods ($goods _id) to get the specified URL and static address,
How can I use the common $db and $ecs without initializing this class in the class URLPath?

Two: Is my writing a bit of a problem? ~ Why is there an error in the other place? It seemed possible to write like this before.

Reply to discussion (solution)

A class variable cannot be declared with the value of a variable, and an additional schema function __construct is required to assign a value

Upstairs, that's right.
