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 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=24300&edit=1
