Yeah, I know--it winds up being a strtol() call. However, since PHP
does interpret octal and hex integer literals, it seems odd that it
won't interpret them when encapsulated in strings. This does look
intentional though, since strtol() is called with a base of 10 in
zend_operators.c (line 259 in cvs); replacing it with a base of 0
gives the result I (personally) would have expected.
So--is it intentional because it would screw some people up to have
left-zero-padded string numbers interpreted as octals, or is there
another deeper reason that using 0 as the base for strtol() is a bad
idea, or is this unintentional?
