The range Function
The range
function creates an array with a range of
elements. For example, you can create an array
filled with numbers from 1
to 100
or letters from 'a'
to 'z'
.
The range that the function generates is set by
parameters: the first parameter is the start,
and the second is the end.
The third optional parameter of the function sets the step with which the generation will proceed.
Syntax
range(string|int|float $start, string|int|float $end, int|float $step = 1): array
Example
Let's create an array filled with numbers
from 1
to 5
:
<?php
var_dump(range(1, 5));
?>
Code execution result:
[1, 2, 3, 4, 5]
Example
Let's create an array filled with numbers
from 5
to 1
:
<?php
var_dump(range(5, 1));
?>
Code execution result:
[5, 4, 3, 2, 1]
Example
Let's create an array filled with numbers
from 0
to 10
with a step of 2
:
<?php
var_dump(range(0, 10, 2));
?>
Code execution result:
[0, 2, 4, 6, 8, 10]
Example
Let's create an array filled with letters
from 'a'
to 'e'
:
<?php
var_dump(range('a', 'e'));
?>
Code execution result:
['a', 'b', 'c', 'd', 'e']
