More PHP oddities

Apparently, true prints as 1, while false prints as the empty string.

Also, empty() considers the string and the number 0 to be empty.

PHP and fgets()

In an attempt to mimic behaviour of fgets in C, it appears that PHP defines the $length argument as the number of characters - 1 that should be read.
The length argument to fgets in C includes the '\0', but PHP really has no reason to care about that issue.
