What is the bug here?

It shows this for me, which is perfectly normal:
bool(false)
string(0) ""

bool(false)
string(1) "1"

bool(false)
int(2)

bool(false)
int(3)

bool(false)
int(4)

bool(false)
int(5)

bool(false)
int(6)

bool(false)
int(7)

bool(false)
int(8)

bool(false)
int(9)

Why not "Type Juggling" for boolean ?

IMO the bool-stuff works ok, but it's strange that it jumps from string to int.

This bug has been fixed in CVS. You can grab a snapshot of the
CVS version at http://snaps.php.net/. In case this was a documentation 
problem, the fix will show up soon at http://www.php.net/manual/.
In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites.
Thank you for the report, and for helping us make PHP better.

Jani, the type juggling for '' is actually correct, as the string value "1" gets converted to an int first before the increment operator is applied.
Andrew, I implemented type juggling for bools.

I see, what you removed this changes from CVS ?

It is possible to receive comments?
