<?php /* * PHP 5.6 Variadics allow us to pack arguments into arrays from the function prototype! * Typically you would use a combination of func_get_args and array_slice to grab these * function arguments from the stack frame, but Variadics make the syntax much nicer. * The function prototype is easier to read and more clearly signifies that it's a * Variadic function... */ // Pre PHP 5.6 you would do the following ... function bond($agent) { $bondingAgents = array_slice(func_get_args(), 1); $bonding = ""; foreach ($bondingAgents as $bond) { $bonding .= "$agent-$bond\n"; } return $bonding; } // With PHp 5.6 you cna do this instead ... function newBond($agent, ...$bondingAgents) { $bonding = ""; foreach($bondingAgents as $bond) { $bonding .= "$agent-$bond\n"; } return $bonding; } header('Content-type: text/plain'); echo "Pre-5.6 Result...\n\n"; echo bond("Hydrogen", "Oxide", "Peroxide", "Dioxide"); echo "5.6 Result...\n\n"; echo newBond("Hydrogen", "Oxide", "Peroxide", "Dioxide");
