Align when multiline

When the checkbox is selected and the New line after '(' checkbox is cleared, each item in a for / foreach loop expression, which after wrapping starts on a new line, is aligned by the first item, which remains unwrapped.

for ($i = 0;
     $i < $x;
     $i++) {

    $i < $x;
    $i++) {
    $y += $i;
}

New line after '('

If selected, expressions in for / foreach loops are displayed on the next line after the opening parenthesis. Otherwise, they are displayed on the same line.

for (
    $i = 0; $i < $a; $i++) {
