How to manipulate multidimensional arrays with forms

Hi,

I have recently started learning php. I have created a form using HTML. On this form a user has to choose a “Departure City” and after they validate the form, All the possible destinations (stored in a multidimensional table) should show only from the “Departure City selected”.

With my code, all destinations show even those not from the selected city.

How do I show only the Destination cities from the Departure cities selected using a simple code?

$trips= array (

0=&gt; array ('Departure'=&gt;'Paris', 'Arrival'=&gt;'Nantes', 'departureTime'=&gt;'11:00', 'arrivalTime'=&gt;'12:34', 'Driver'=&gt;'Thomas'),

1=&gt; array ('Departure'=&gt;'Orleans', 'Arrival'=&gt;'Nantes', 'departureTime'=&gt;'05:15', 'arrivalTime'=&gt;'09:33', 'Driver'=&gt;'Mathieu'),

2=&gt; array ('Departure'=&gt;'Dublin', 'Arrival'=&gt;'Tours', 'departureTime'=&gt;'07:23', 'arrivalTime'=&gt;'08:50', 'Driver'=&gt;'Nathanael'),

3=&gt; array ('Departure'=&gt;'Paris', 'Arrival'=&gt;'Orleans', 'departureTime'=&gt;'03:00', 'arrivalTime'=&gt;'05:26', 'Driver'=&gt;'Clément'),

4=&gt; array ('Departure'=&gt;'Paris', 'Arrival'=&gt;'Nice', 'departureTime'=&gt;'10:00', 'arrivalTime'=&gt;'12:09', 'Driver'=&gt;'Audrey'),

5=&gt; array ('Departure'=&gt;'Nice', 'Arrival'=&gt;'Nantes', 'departureTime'=&gt;'10:40', 'arrivalTime'=&gt;'13:00', 'Driver'=&gt;'Pollux'),

6=&gt; array ('Departure'=&gt;'Nice', 'Arrival'=&gt;'Tours', 'departureTime'=&gt;'11:00', 'arrivalTime'=&gt;'16:10', 'Driver'=&gt;'Edouard'),

7=&gt; array ('Departure'=&gt;'Tours', 'Arrival'=&gt;'Amboise', 'departureTime'=&gt;'16:00', 'arrivalTime'=&gt;'18:40', 'Driver'=&gt;'Priscillia'),

8=&gt; array ('Departure'=&gt;'Nice', 'Arrival'=&gt;'Nantes', 'departureTime'=&gt;'12:00', 'arrivalTime'=&gt;'16:00', 'Driver'=&gt;'Charlotte'),

);

This is my table list of options. So if the user chooses Paris as the departure city, when he/she submits the form, then the site should show details of arrays 0, 3 and 4 only. If the user chooses Nice as the departure and then submits the form, then the site should show details of arrays 5, 6 and 8 only etc…

Thank you for your help.

foreach ($trips as $k => $v) {
    if ($v['Departure'] == $_POST['DepartureCity']) {
        echo "Depart: {$v['Departure']} Arrive: {$v['Arrival']} Depart Time: {$v['departureTime']} Arrival: {$v['arrivalTime']} Driver:{$v['Driver']}<br>";
    }
}
