PHP - Classes and Objects

Consider this PHP code:

class Status {
    const OK = 1;
    const ERROR = 0;
    public static function getMessage($code) {
        return match($code) {
            self::OK => 'Success',
            self::ERROR => 'Failure',
            default => 'Unknown'
        };
    }
}
echo Status::getMessage(Status::OK);

What is the output?

AOK

BError

C1

DSuccess

Step-by-Step Solution

Solution:

Step 1: Understand constant usage in match expression
Constants OK and ERROR are used as keys in match to return messages.
Step 2: Call getMessage with Status::OK (1)
Match returns 'Success' for code 1.
Final Answer:
Success -> Option D
Quick Check:
Constants used as keys return mapped string [OK]

Quick Trick: Use self::CONST inside static methods for constants [OK]

Common Mistakes:

Expecting constant name instead of mapped string
Confusing constant value with output
Not using self:: inside class
