PDO 限制和偏移

问题描述

可能的重复:
PHP PDO bindValue 限制

在prepare语句中使用LIMIT和/或OFFSET时无法显示数据，但是如果我不使用LIMIT和OFFSET，我可以显示雷磊"，代码看起来有问题吗?

I could not display the data when using LIMIT and/or OFFSET in the prepare statement, but I can show "Lei Lei" if I don't use the LIMIT and OFFSET, does the code look wrong?

$statement = $conn->prepare("SELECT id,username FROM public2 WHERE username = :name LIMIT :sta OFFSET :ppage");
$name = "Lei Lei";
$statement->execute(array(':name' => $name,':sta' => $start,':ppage' => $per_page));

这与原来有效的代码有所不同:

This have been change from the original code which worked:

$query_pag_data = "SELECT id,username from public2 LIMIT $start, $per_page";
$result_pag_data = mysql_query($query_pag_data) or die('MySql Error' . mysql_error());

推荐答案

我找到了答案！

$statement->bindValue(':sta1', (int) $start, PDO::PARAM_INT); 

确实有效
