php - How to load two fields returned by a query into an associative array? -


i have complex query structure:

select driver, travel  travels ...

returns this:

david paris david oslo jhon  amsterdam david madrid marco barcelona jhon  rome

well, want return information in 2 parts. mean, first of array of drivers contains:

david jhon marco

and according user's choice want travels of driver. assuming choose david, return array with:

paris oslo madrid

i know can separating 2 queries, but, said, complex query on database many records in way i'd save time.

i'm using php... how this?, associative array? give me example, please?

i hope clear in explanation. in advance.

for both save them first in array:

while ($row = $result->fetch_object()) { // mysqli. mysql use mysql_fetch_object($result)    $travel[$row->driver][] = $row->travel; }

for first:

$drivers = array_keys($travel);

for second:

$locations = $travel[$driver];
