all happy visitors of Paris know about the 'arrondissement', an 
administrative division of the city...  20 divisions

selecting them from a city table I can map them as :

['Paris 1'  , 'Paris 10' , 'Paris 11' , .....  'Paris 19' , 'Paris 2' , 
 'Paris 20' , 'Paris 3' , .... 'Paris 9' ]

is there any way to sort this array and get :

['Paris 1'  , 'Paris 2' , 'Paris 3' , .... 'Paris 9' , 'Paris 10' , 
'Paris 11' , .....  'Paris 19' , 'Paris 20' ]

which seems betetr in a list... ;-))

thanks for your light
