Array:
Defination
An array is a variable that stores one or more values.
Each value can be accessed using an index number, such as:
$numbers = array(10, 20, 30); echo $numbers[0]; // Output: 10
Values can be accessed using index numbers such as 0, 1, and 2.
Note: An array can be indexed using numeric indices.
There are many types of arrays, which are listed below:
- Indexed Array – uses numeric indexes (like 0, 1, 2..)
- Associative Array – uses named keys (like "name", "age"...)
- Multidimensional Array – contains one or more arrays inside another array.
