PHP range()

The range() function generates an array containing a sequence of elements. The function allows for the specification of a starting point, an endpoint, and an optional step value to determine the increment between elements.

Syntax

range($start, $end, $step)

The range() function accepts three parameters as described below:

• $start: The starting value of the sequence.
• $end: The endpoint value of the sequence.
• $step(optional): The increment between elements in the sequence. If not specified, the default value is 1.

The range() function returns an array of elements from $start to $end, and is inclusive (the $end value will be the final element in the array).

Note: If the $start parameter is higher than the $end parameter, the range array will be from high to low.

Example

The following example uses the range() function to generate a sequence of even numbers from 2 to 10 with a step of 2.

<?php
$evenNumbers = range(2, 10, 2);
foreach ($evenNumbers as $num) {
    echo $num . ' ';
}
?>
