在2个数组内循环

Question

I have 2 arrays, and I am trying to find out which checkboxes should be checked and which not. I do get correct results, but if 2 checkboxes should be checked, I get 2 sets of checkboxes, if 3 should be checked i get 3 set of checkboxes and so on... I make a numerous attempts to avoid that using break and continue statements, without success.

Here is the code:

<?php
foreach ($rooms as $room) {
    foreach ($searchQuerySelectedRooms as $selRoom) {
        if ($room['roomID'] != $selRoom) {
?>
<input type="checkbox" name="rooms[]" value="<?php echo $room['roomID']; ?>" style="float:left;width:20px; margin-right:10px;"/>
<?php
        } else {
?>
<input type="checkbox" name="rooms[]" value="<?php echo $room['roomID']; ?>" style="float:left;width:20px; margin-right:10px;" checked="checked"/>
<?php                                                                  
        } 
    }
}
?>

Array $rooms prints the following:

Array
(
[0] => Array
    (
        [roomID] => 2
        [hotelID] => 10
        [roomtypeID] => 1
        [roomNumber] => 1
    )

[1] => Array
    (
        [roomID] => 3
        [hotelID] => 10
        [roomtypeID] => 1
        [roomNumber] => 2
    )

[2] => Array
    (
        [roomID] => 4
        [hotelID] => 10
        [roomtypeID] => 2
        [roomNumber] => 3
    )
[3] => Array
    (
        [roomID] => 5
        [hotelID] => 10
        [roomtypeID] => 2
        [roomNumber] => 4
    )
)

While array $searchQuerySelectedRooms prints the following:

Array
(
    [0] => 2
    [1] => 3
    [2] => 4
)

Any help will be deeply appreciated.

please check this code

<?php
foreach ($rooms as $room) {
    if (in_array($room['roomID'], $searchQuerySelectedRooms)) {
        $checker = 'checked="checked"';
    } else {
        $checker = '';
    }

    echo '<input type="checkbox" name="rooms[]" value="' . $room['roomID'] . '" style="float:left;width:20px; margin-right:10px;" ' . $checker . '/>';

}
?>
