Description:
------------
If you are in a "for" loop you can't modify the itterative variable.
PHP seems to revert it the value at the start of the itteration.
This is standard behaviour for both C and Java. The PHP documentation
does not forbid this, and the syntax suggests it is possible, so I
assume this is a bug and not a design decision.
Reproduce code:
---------------
for ($n = 0; $n < 4; $n++)
{
print("$n\n");
if ($n = 2)
$n = 4;
}
Expected result:
----------------
0
1
2
Actual result:
--------------
0
1
2
3
