<?php

// There are two ways to create an array.
// First, you can use the array construct to pass in values separated by commas
// and it will return an array.
$taskList = array('grocery store', 'change car oil');

// Second, you can surround the list in square brackets.
// This style is the most common and recommended form
// of creating an array.
$groceryList = ['bread', 'milk', 'eggs'];

// PHP will automatically assign index keys for each value in an array
// starting with 0. So, to access a value in an array you will
// pass the key number into brackets after the variable name.
echo $groceryList[0] . "\n";
echo $groceryList[1] . "\n";

// You can also assign keys in an array using numbers or strings.
// It is very common to create an array with string keys. The pattern
// is called an associative array or a map.
$car = ['make' => 'Toyota', 'model' => 'Camry'];

// To access the value in an associative array, just use the string key in brackets
// after the variable name.
echo $car['model'] . "\n";
