Validating Boolean Values and Float Numbers with Filters in PHP 5
August 06, 2009 @ 07:51:05

Continuing their "validation in PHP" series, DevShed has posted this new tutorial looking at the validation of boolean values and float numbers in PHP5 applications (with the filter extension).

As you learned in previous parts of the series, the filter extension permits you to validate elements of a given array very easily as well. Therefore, in this fourth chapter I'm going to explain how to check for Boolean values in arrays, as well as how to validate float numbers using another handy filter.

the examples are pretty simple, running a filter_var on the values to check if it's a boolean and to require that the set of values comes in as an array.
