PHP 5 Arrays

<?php $cars = array("Volvo", "BMW", "Toyota"); echo "I like " . $cars[0] . ", " . $cars[1] . " and " . $cars[2] . "."; ?>

In this case it's faster to echo with a comma -- echo 'I like ', $cars[0], ', and so on... '; than to build a concatenated string before echoing out the contents. Also as of PHP 5.6 you should use the new syntax for array declarations and not the old style of array(); $cars = ['Volvo', 'BMW', 'Toyota']; // similar to javascript.
