[PHP-DOC] #18411 [Opn]: print_r(FALSE) not consistant with print_r(TRUE) From: rasmus <email protected>

 New Comment:

TRUE has always been 1 and FALSE "". To me it would be inconsistent if
you did strlen(FALSE) and got TRUE, for example. It just needs to be
documented better.

As the boolean page holds information on converting to boolean, I have
expected this info to be found on the strings page, but it's not there
;) Though the integer page has info on converting to integer... So this
should be explained on the strings page IMHO.

This is expected behavior, but I can not find this in the manual either
(atleast not on
http://www.php.net/manual/en/language.types.boolean.php).
Making it a documentation problem.

No doubt there is a reason for:

print_r(TRUE) displays 1
print_r(FALSE) displays nothing

But too me, it just seems inconsistant, bad practise and very
confusing.

I can find nothing in the documentation I have on, why it is like this,
as the text indicates 0 is to FALSE as 1 is to TRUE.

It is also obvious from your bug list, that the area of TRUE/FALSE and
1/0 has its problems.
