有什么方法可以获取使用mysqli预准备语句返回的行数？

Question

想知道是否有一种方法可以使用mysqli准备好的语句从查询返回的行数，类似于

mysql_num_rows($query);

Answer 1

Presuming you're doing something like:

$result = $statement->execute();

You can get the number of rows with

$result->num_rows;

See the manual .

Answer 2

Use this code:

$result = $mysqli->query($query);
$num_rows = $result->num_rows($result);
