That's what I was wondering too, especially considering there is a helper function that just wraps it. Seems rather unnecessary. <?php function pipe(...$args) { // Retrive first argument as initial value $value = array_shift($args); // Call the functions passing $value and assign its return foreach($args as $func) $value = $func($value); // Return computed value return $value; } echo pipe("10 WAYS to EAT more HEALTHY", fn($s) => strtolower($s), fn($s) => str_replace(" ", "-", $s) ); Works just as well.
