#20548 [NEW]: Decrement ("$x[$y]--") doesn't work on uninitiated variable

[prgallier]

From:             [EMAIL PROTECTED]
Operating system: Linux 2.4
PHP version:      4.3.0RC1
PHP Bug Type:     Math related
Bug description:  Decrement ("$x[$y]--") doesn't work on uninitiated variable

The following:
  $score[$num]--;
does not affect $score[$num] if $score[$num] is uninitiated.
Using $score[$num]++ does work, however.
This is inconsistent.
