Question

I managed to solve my problem with getAll and loop after it. But as I’m not very good with mysql queries and such, I decided to ask you if there’s a way to get using getAssoc from table:

A | B | C
1 | 2 | 3
1 | 3 | 4

an array with structure:

$array[1][2]=3
      [1][3]=4

Answer 1

Is this what you want

$output = array();

while ($row = mysql_fetch_array($result)){
   $first_col = $row['A'];
   $second_col = $row['B'];
   $third_col = $row['C'];
   $output[$first_col][$second_col] = $third_col;
}

Also remember, don’t use mysql_*, PHP isn’t supporting it anymore. Better to switch to mysqli or PDO
