Yes I know, but I wonder what is the master reason behind this line of
doing things ?
The fact that something is documented shoudn't make it automatically
right. Are there scripts where people are putting strings into count
by purpose, not by an accident ? Is this behavior having some grand
purpose behind id, or is it just a historical accident for early days
of php ?
