+// 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";
