What's new in PHP 8

PHP 8.5 introduces the highly requested Pipe Operator (|>), enabling developers to chain function calls and transformations in a clear, top-to-bottom readable flow. Instead of nesting functions inside out like functionA(functionB(functionC($val))), the pipe operator passes the result of the left expression into the right function as its first argument or designated placeholder.

PHP 8.5 Example:

$rawString = "  PHP 8.5 is awesome!  ";

$result = $rawString
    |> 'trim'
    |> 'strtolower'
    |> fn($s) => str_replace(' ', '-', $s);

echo $result; // Outputs: php-8.5-is-awesome!
