Instead it points to the next key after the one which was current when the first change was made to the array we are currently iterating. Reproduce code: --------------- $ar = array('val1', 'val2', 'val3'); var_dump(key($ar)); echo '<br>'; foreach ($ar as $key=>$val) { echo $key.'=>'.$val.'<br>'; } var_dump(key($ar)); echo '-------'; foreach ($ar as $key=>$val) { echo $key.'=>'.$val.'<br>'; $ar[2] = $ar[2]; } var_dump(key($ar)); echo '-------'; foreach ($ar as $key=>$val) { echo $key.'=>'.$val.'<br>'; if ($key==1) $ar[2] = $ar[2]; } var_dump(key($ar)); Expected result: ---------------- int(0) 0=>val1 1=>val2 2=>val3 NULL ------- 0=>val1 1=>val2 2=>val3 NULL ------- 0=>val1 1=>val2 2=>val3 NULL Actual result: -------------- int(0) 0=>val1 1=>val2 2=>val3 NULL ------- 0=>val1 1=>val2 2=>val3 int(1) ------- 0=>val1 1=>val2 2=>val3 int(2) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=42828&edit=1
