Quick Reference
The PHP range() function creates an array containing a range of elements from low to high.
If the low parameter is higher than the high parameter, the range array will be from high to low.
<?php
$my_numbers = range(1, 5);
print_r ($my_numbers);
?>Note
Arrays count starting from zero NOT one. So item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on.
Output
Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 )Syntax

| Parameter | Description |

PHP Notes:
- When using PHP, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
- Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
