我对预处理语句还比较陌生,不确定自己是否做得正确。
这是我的尝试:
$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>';
}
}
当我尝试运行以下代码时,出现了"ServerError"错误: $res = $stmt->get_result();
造成了这个错误,但我不确定原因。
PHP致命错误:在第61行/home/mypage/public_html/TEST/preparedstatement.php中调用未定义的mysqli_stmt :: get_result()方法
