Array type question

The_Chancer

I am passing two arrays from a form, one of which is $room and the other is $order - I need to pull the correct info from each as follows:

$room $order
Room1 1
Room2 2
Room3 3
Room4 4

I can't get these as key => value as the order is changeable.

I need to be able to pop the last item out of each array to put into a database, but how do I do this ?

Using foreach would give me the individual values, as would each and array_pop, but which one to use ?

Help and advice is welcome....

Thanks

between each, foreach, and array_pop there is no best solution, it depends on what you are trying to do.

ok im assuming that and order of ( 3, 1, 2 ) means:
the third entry of $room, then
the frist entry of $room, then
the second entry of $room,

so with :

$room = array( 'room1', 'room2', 'room3' );
$order = array( 3, 1, 2 )

you want to end up with an ordered list

$ordered_rooms = array( 'room3', 'room1', 'room2' )

if that is true just do this

foreach ( $order as $room_index ) {
$next_room = $room[$room_index-1];
}

does this help... if not maybe you could post a vanilla example kinda like mine here to help explain

That is correct in the first instance where Room1 has order 1 etc, but I will explain further.

User form lists room names and option to change listing order.

Form gets submitted and new values for each are passed as two arrays.

Array1 = $room
Array2 = $order

The order that they are now in the array will be the order I want them, which could be:

$room $order
room2 3
room1 2
room3 1

What I would like to do is say,

"Get the last item in each array and do this....

update rooms (room_name, list_order) VALUES ($room, $order)

for each of the variables in the array"

But I don't exactly want an ordered list, but I want the values in the array to be give to me in the same order from both arrays...

I have though that foreach would do this, but it can't do it concurrently can it ? as they would have to be nested.. but would this be possible ?? (brain may have just kicked in...)

foreach ($room as $roomname)
{
$listorder = array_pop($order);
insert SQL statement here to update with $roomname and $listorder;
}

Seems to work OK in principle - although the second array is in reverse order...

Tried using array_reverse - but doesn't seem to work either....

Any other ideas ?

array_shift will pop one off the top of the array

Ah-ha - works like a charm now.. cheers
