[SOLVED] Sort Array

[Wallzy]

Hi,

 

I am a newbie to PHP.  I would like to do something with an array but I am not sure how exactly I should go about it so any pointers/help would be greatly appriciated.  I have an array of vehicle details as follows:

 

$vehicleDetails[0]  ('id' = '1', 'make' = 'VW', 'model' = 'Golf', 'color = 'silver', 'doors' = '5')

$vehicleDetails[1]  ('id' = '2', 'make' = 'Audi', 'model' = 'A3', 'color = 'black', 'doors' = '3')

$vehicleDetails[2]  ('id' = '3', 'make' = 'VW', 'model' = 'Passat', 'color = 'red', 'doors' = '4')

$vehicleDetails[3]  ('id' = '4', 'make' = 'Audi', 'model' = 'A4', 'color = 'blue', 'doors' = '5')

$vehicleDetails[4]  ('id' = '4', 'make' = 'Audi', 'model' = 'A6', 'color = 'white', 'doors' = '4)

 

I would like to be able to take this array and from it produce a new associative array which has

$vehicle[0]["VW"] $vehicleDetails[0]  ('id' = '1', 'make' = 'VW', 'model' = 'Golf', 'color = 'silver', 'doors' = '5')

$vehicle[0]["VW"] $vehicleDetails[1]  ('id' = '1', 'make' = 'VW', 'model' = 'Golf', 'color = 'silver', 'doors' = '5')

$vehicle[1]["Audi"] $vehicleDetails[0]  ('id' = '2', 'model' = 'A3', 'color = 'black', 'doors' = '3')

$vehicle[1]["Audi"] $vehicleDetails[1]  ('id' = '4', 'model' = 'A4', 'color = 'blue', 'doors' = '5')

$vehicle[1]["Audi"] $vehicleDetails[2]  ('id' = '4', 'model' = 'A6', 'color = 'white', 'doors' = '4)

 

So that I have all of the VW vehicle details grouped together in the $vehicle array at position 1 with a sub array holding the details of the first VW vehicle, another sub array hold the second VW vehicle details and so on. 

 

Thanks in advance.

$byMake = array();

                                        'model' => $cardata['model'],
