What are the advantages of the match expression in PHP 8 over the traditional switch statement?

Short answer

match is an expression that directly returns a value, uses strict comparison (===), needs no break statements, and throws UnhandledMatchError if no case matches.

Explanation

The traditional switch statement uses loose comparison (==) and requires a break after each case to prevent fallthrough. The match expression adds concise, safe, functional syntax with strict type matching and directly returns the result for assignment to a variable.

Code example

$statusText = match ($code) {
    200, 201 => "Success",
    400 => "Bad Request",
    404 => "Not Found",
    default => "Unknown Status",
};

Common mistakes

• Forgetting to provide a default case in a match expression when not all possible cases are covered.
