Reworded: str->int conversion isn't binary safe (strtol isn't...).
A fix would make the commonly (implicitely) used str->int conversion slower... I can think of a
few ways to fix this, but didn't check the performance impact.
In PHP, everything is supposed to work regardless of ascii 0 bytes in a string.

if you convert a string containing chr(0) characters to an int, php cuts off conversion on reaching
the first ascii 0. The resulting integer is incorrect, of course.
I found it out having a string constructed of concatenated single characters which would not convert
correctly. However, checking the string length would show more characters than those visible.
Basic string handling stuff seems to work ok on those strings, however. This seems weird because I
would have expected php to consider the first 0 character terminate the string, which it does not.
Or does it?
