Array variables

Instead of using several unique variables to store information, you can use an array variable. The elements in an array variable are numbered, starting with zero. The number (index) of an element is inside square brackets.

Examples

Example 10

Array variable $phonenumber.

$phonenumber[0] = "031-90510";
$phonenumber[1] = "020-222222";
$phonenumber[2] = "031-183413";
