PHP how to use range() for float numbers

Question

Is there a way to use PHP range() for a really small number? like below?

range(0.54,0.58);

Doing this creates an error.

range(): step exceeds the specified range in

Answer 1

The third parameter is the step.
Reading the documentation is a very good place to start.

If you read you will see that you can set the step to something that can increment between your limits.
The error message is simply telling you that it cannot increment 0.54 by 1 without going over 0.58 - think about, it 1 + 0.54 is more than 0.58!

Using this line instead will give you the desired output.

range(0.54, 0.58, 0.01);

Answer 2

The error message is self-explanatory: the default value of $range (the third argument of range()) is 1 and using it produces an empty range.

Provide a third argument to range(). From the value of $start and $end I think 0.01 is the step you need:

range(0.54, 0.58, 0.01)
