PHP array

All the variables you have used have held only a single value.

Array variables are “special” because they can hold more than one value in one single variable.

This makes them particularly useful for storing related values.

There are three types of array.

Indexed array : An array with a numeric index
Associative array : An array where each key is associated with a value
Multidimensional array : An array containing one or more array
