What are the different ways to define arrays in PHP?

In PHP, there are several ways to define an array:

1. You can define an array using the array() function. For example:

$myArray = array("apple", "banana", "orange");

1. Starting from PHP 5.4, you can use simplified array syntax to define arrays. For example:

$myArray = ["apple", "banana", "orange"];

1. You can create an array with elements within a specified range using the range() function. For example:

$numbers = range(1, 10);

1. Associative arrays can be defined using key-value pairs.

$fruits = array("apple" => "red", "banana" => "yellow", "orange" => "orange");

1. By using the list() function, you can assign the values in an array to a set of variables. For example:

$myArray = array("apple", "banana", "orange");
list($fruit1, $fruit2, $fruit3) = $myArray;
