正如Madan Sapkota所说：＆＃34; if（！$ query）{仅检查是否存在任何错误＆＃34;。

你需要使用一个函数来计算结果，比如mysqli_stmt_num_rows（）：

if(mysqli_stmt_num_rows ( $stmt ) == 0 ){ echo "there is no result";}
// The while loop after won't be run when no result are found, no need to put an else here.
while (mysqli_stmt_fetch($stmt)) {
  ...    
}
