What are the difference between PHP 8 Match expression vs PHP 7 switch case?

PHP 8 Match expression code

echo match (8.0) {
    '8.0' => "Oh no!",
     8.0 => "This is what I expected",
};
//> This is what I expected

PHP 7 switch code

switch (8.0) {
  case '8.0':
    $result = "Oh no!";
    break;
  case 8.0:
    $result = "This is what I expected";
    break;
}
echo $result;
//> Oh no!

Which one give better performance?
Use case of match and switch.

Answer

Solution:

Main differences:

match is an expression, while switch is statement
match uses strict comparison, while switch uses loose
match evaluates only one value, while switch may evaluate more (depending on break statement)
match allows only single-line expression, while switch allows block of statements

Match expression has got already its page in the PHP documentation if you want to know more: https://www.php.net/manual/en/control-structures.match.php

The match expression branches evaluation based on an identity check of a value. Similarly to a switch statement, a match expression has a subject expression that is compared against multiple alternatives. Unlike switch, it will evaluate to a value much like ternary expressions. Unlike switch, the comparison is an identity check (===) rather than a weak equality check (==). Match expressions are available as of PHP 8.0.0.
