PHP Bug Type: Scripting Engine problem
Bug description: For loops against the alphabet don't function properly
Description:
------------
When trying to loop 'a' through 'z' using
for ($i = 'a'; $i < 'z'; $i++)
print $i;
it loops a-y as it should, but when you try
for ($i = 'a'; $i <= 'z'; $i++)
print $i;
instead of going a-z it goes a-yz doubling up the letters after a-z
a-z
aa-az
ba-bz
ca-cz
... etc
I know this breaks under php5, and under php4.
Reproduce code:
---------------
for ($i = 'a'; $i < 'z'; ++$i)
{
print "$i\n";
}
and
for ($i = 'a'; $i <= 'z'; ++$i)
{
print "$i\n";
}
Expected result:
----------------
abcdefghijklmnopqrstuvwxyz
(seperated by new lines)
Actual result:
--------------
abcdefghijklmnopqrstuvwxyzaaabacadaeaf....yxyyyz
