Add a warning about a problem with validating with PHP FILTER_VALIDATE_FLOAT.

Recommended Posts

Hello All,


On the page about the PHP filter 'FILTER_VALIDATE_INT' there is a warming about a problem with this filter. (The filter does not validate 0 (zero) as an integer.)


I found that the same kind of problem occurs with FLOAT.
I think it would be good to add this warning to the page of the 'FILTER_VALIDATE_FLOAT' as well.

Kind regards,
