PHP: Can range() be used for fractions?

Question

Could it be possible to use the range() function in PHP to generate a list of fractions or decimals?

Answer 1

Yeah, if you specify the step (third parameter). This parameter is only available in PHP 5, but you should be using that by now anyway.

For example, to generate decimals between 0 and 1, inclusive, in intervals of 0.1:

print_r(range(0, 1, 0.1));

Output:

Array
(
    [0] => 0
    [1] => 0.1
    [2] => 0.2
    [3] => 0.3
    [4] => 0.4
    [5] => 0.5
    [6] => 0.6
    [7] => 0.7
    [8] => 0.8
    [9] => 0.9
    [10] => 1
)
