What is a list data type?

A list data type is a data structure that represents an ordered sequence of elements. In PHP, list types can be considered arrays, which can contain elements of any type and are indexed by integers or strings.

Features of the list type:

• Orderliness: elements have a specific order.
• Mutability: elements can be added, removed, and modified.
• Index access: elements can be accessed by their position.

Example of a list (array) in PHP:

$fruits = ['apple', 'banana', 'cherry'];

// Adding an element
$fruits[] = 'orange';

// Accessing an element
echo $fruits[1]; // banana

// Modifying an element
$fruits[0] = 'pear';

// Removing an element
unset($fruits[2]);

Thus, the list data type is a convenient way to store and work with sequences of elements.
