Question

How is it possible to retrieve the mysql_query from a function? For instance:

class A() {
   ...
   function getAll($l=1) {
      ...
      $result = mysql_query($query); 
      return $result
   }
   ...
}

$a = new A();
$r = $a -> getAll(2);
while ($row = mysql_fetch_assoc($r)) {
   // do something
} 

This code above does not work when I return $result from the function. However, when I use the mysql_fetch_assoc function in getAll function, it works perfectly. So basically, my question is how to return a mysql result set from a function?

** EDIT **

I actually get no errors. The while statement used liked above will just not execute. But the query works perfectly when I execute it from within the getAll function.

Don’t return the result resource from the query, but rather return the data extracted from that resource:

$data = array();

while ( $row = mysql_fetch_assoc($result) ) {
    $data[] = $row;
}

return $data;
