An indexed array in PHP is an array that uses numeric keys to access its elements. The keys are automatically assigned by PHP, starting from 0 and incrementing by 1 for each element. Indexed arrays maintain the order of their elements, and each element can be accessed using its corresponding numeric key. This type of array is commonly used when you need to store and retrieve elements in a sequential manner. Learn more: https://www.php.net/manual/en/language.types.array.php
