Hey internals,
A longstanding PHP bug is that invalid octal digits simply terminate the
literal and are ignored, rather than generating a compile error. Thus, this is
valid:
$x = 0109; // same as 010, or 8
I see no particular reason why this behaviour should be preserved. I’ve written
a patch that would finally fix it, and avoid similar parsing issues in future
(e.g. the resurgence of the hex addition bug), by erroring when strtol doesn’t
reach the end of the literal.
The pull request is here: https://github.com/php/php-src/pull/987
I think this would be an acceptable BC break for PHP 7.
Thoughts?
