A php sqlite to json converter page

Next I build basically a quick converter page to convert an sqlite query result into json

function jsonOutput($query)
{
  #json convert
  $ofirst = true;
  print "[\n";
  foreach ($query as $row)
  {
    if($ofirst) $ofirst = false;
    else       print ",\n";
    
    $first = true;
    print "{";
    foreach ($row as $key => $value)
    {
      if($first) $first = false;
      else       print ",";
      if(is_numeric($value))
        print $key . ': ' . $value;
      else
        print $key . ': "' . $value . '"';
    }
    print "}";
  }
  print "\n]\n";
}
