PHP Match

PHP Match Expression

Introduced in PHP 8.0, the match expression provides a shorter, safer, and faster alternative to the switch statement.

Match vs. Switch

There are three main differences between match and switch:

1. Strict Comparison: match does a strict type comparison (===), whereas switch does a loose comparison (==).
2. No Break Required: match automatically breaks execution when it finds a matching block, preventing "fall-through" errors.
3. Returns a Value: The match expression returns a value, meaning you can assign its result directly to a variable.

<?php
$status = 200;

$message = match ($status) {
  200, 201 => 'Success!',
  400, 404 => 'Bad Request!',
  500 => 'Server Error!',
  default => 'Unknown Status',
};
echo $message;
?>
