Question

an easy one, its long time i do not use mysql queries so maybe someone can help me out with this nooby question, i have a contacts table, id, name, and city.. i want to get all the contacts listed as follows.

city 1
--------
contact1
contact2
contact3

city 2
--------
contact4
contact7
contact10

city 3
--------
contact5
contact6
contact8

I do not want to use any additional php coding, just get the sql result like this

city 1 
   -> contact 1
   -> contact 2
   -> contact 3
city 2 
   -> contact 4
   -> contact 7
   -> contact 10

…

then fill the result in a php object and do like this:

foreach (cities as city)
{ 
   // code here
}

Thanks in advance

Use GROUP_CONCAT

SELECT  city, GROUP_CONCAT(name)
FROM    contacts
GROUP BY    city
