Match Expression in PHP 8

Match expression is a new feature that is added in PHP 8. It is very much similar to switch-case statements, but it provides more safe semantics.

• Match expression does not use the 'case and break' structure of switch-case statements. It supports joint conditions, and it returns a value rather than entering a new code block.

• We can store match results in a variable because it is an expression.

• Match expression does not need a break statement like a switch. It supports only single-line expression.

Example: PHP 7 Using Switch Statement

 Live Demo

<?php
   switch (1.0) {
      case '1.0':
         $result = "Hello World!";
         break;
      case 1.0:
         $result = "Looks good";
         break;
   }
   echo $result;
?>

Output

Hello World!

Example: Above PHP 7 Code Using PHP 8 Match Expression

<?php
   echo match (1.0) {
      '1.0' => "Hello World!",
      1.0 => "Looks Good!",
   };
?>

Output

Looks Good!

Example: Using PHP 8 Match Expression

<?php
   echo match (2) {
      1 => 'Company',
      2 => 'Department',
      3 => 'Employee',
   };
?>

Output

Employee
