Reported By: prgallier@yahoo.com
Status: Verified
Bug Type: Scripting Engine problem
Operating System: Linux 2.4
PHP Version: 4.3.0RC1
New Comment:
I just stumbled across this bug recently with an older version (4.1.1)
of PHP on Win32 -- verified that it still exists in 4.3.0. This one
had me going in circles trying to debug. Work-arounds:
$score[$num] -= 1;
or
$score[$num] = $score[$num] - 1;

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