L'obtention de plusieurs lignes à l'aide de l'instruction préparée

Je suis assez nouveau à des déclarations préparées à l'avance et ne suis pas sûr que je suis en train de réaliser ce droit.

Voici ce que j'ai essayer:

$currgame = 310791;
$sql = "SELECT fk_player_id, player_tiles, player_draws, player_turn, player_passes, swapped FROM ".$prefix."_gameplayer WHERE fk_game_id = ?";
$stmt = $mysqli->stmt_init();
$data = array();
if($stmt->prepare($sql)){
$stmt->bind_param('i', $currgame);
$stmt->execute();
$fk_player_id = null; $player_tiles = null; $player_draws = null; $player_turn = null; $player_passes = null; $swapped = null;
$stmt->bind_result($fk_player_id, $player_tiles, $player_draws, $player_turn, $player_passes, $swapped);
$res = $stmt->get_result();
while ($row = $res->fetch_assoc()){
$data[] = $row;
}
$stmt->close(); 
}
//to display own games
foreach ($data as $row) {
if ($row['fk_player_id'] == $playerid) {
$udraws = $row['player_draws']+1; 
$upass = $row['player_passes'];
$uswaps = $row['swapped'];
echo 'uDraws: '.$udraws.'<br>';
echo 'uPass: '.$upass.'<br>';
echo 'uSwaps: '.$uswaps.'<br><br>';
}
}
//to display other games
foreach ($data as $row) {
if ($row['fk_player_id'] != $playerid) {
$opponent = $row['fk_player_id'];
$oppTiles = $row['player_tiles'];
$odraws = $row['player_draws']+1;
$opass = $row['player_passes'];
$oswaps = $row['swapped'];
echo 'oID: '.$opponent.'<br>';
echo 'oTiles: '.$oppTiles.'<br>';
echo 'oDraws: '.$odraws.'<br>';
echo 'oPass: '.$opass.'<br>';
echo 'oSwaps: '.$oswaps.'<br><br>';
}
}

- Je obtenir un "ServerError" lorsque vous essayez d'exécuter ceci: C'est le "$res = $stmt->get_result();" qui fait l'erreur, mais vous ne savez pas pourquoi. S'il vous plaît aider.

Merci d'avance 🙂

$stmt->execute();
$fk_player_id = null; $player_tiles = null; $player_draws = null; $player_turn = null; $player_passes = null; $swapped = null;
$stmt->bind_result($fk_player_id, $player_tiles, $player_draws, $player_turn, $player_passes, $swapped);
while ($row = $stmt->fetch()){
$data[] = $row;
}
$stmt->close(); 
}
echo '<pre>';
print_r($data);
echo '</pre>';
