Hello.

In looking at numer vs string comparison, I think I've found an oddity.

You can successfully compare hex strings ...

var_dump(255 == '0xff');

but not octal strings ...

var_dump(63 == '077');


Is this a bug (lack of octal support) or an unexpected feature (hex support)?


Neither formats are documented in [1].


Regards,

Richard.
