Fetch all rows based on the query into an array

Question

I have the following code:

  //--------------------------------------------------------------------------
  // 2) Query database for data
  //---------------         


        

Answer 1

$result = mysql_query("SELECT * FROM $tableName");  
$arr_json = array();
while ($row = mysql_fetch_assoc($result)) {
   $json = json_encode($row);
   $arr_json[] = $json;
}

EDIT: Looking a j08691's answer, it looks like I might have misunderstood.

Anyway, if you don't know how many columns you have, do this:

$arr = array();
while ($row = mysql_fetch_assoc($result)) {
   $arr2 = array();
   foreach ($row as $val) $arr2[] = $val;
   $arr[] = $arr2;
}
