想像一下我们有一个查询：
SELECT * FROM somewhere WHERE `id` IN(1,5,18,25) ORDER BY `name`;
和要获取的ID数组：$ids = array(1,25)
准备好的语句是准备一个语句是adviced,并多次调用：
$stmt = $MysqLi->prepare('SELECT * FROM somewhere WHERE `id`=?;');
foreach ($ids as $id){
$stmt->bind_params('i',$id);
$stmt->exec();
}
但现在我必须手动对结果进行排序.我有什么不错的选择吗？
你可以这样做：
$ids = array(1,25);
// creates a string containing ?,?,?
$clause = implode(',',array_fill(0,count($ids),'?'));
$stmt = $MysqLi->prepare('SELECT * FROM somewhere WHERE `id` IN (' . $clause . ') ORDER BY `name`;');
call_user_func_array(array($stmt,'bind_param'),$ids);
$stmt->execute();
// loop through results
使用这个,你调用bind_param为每个id,你有排序完成由MysqL.
