在我的本地/开发环境中,MySQLi查询执行正常.但是,当我在我的Web主机环境中上传它时,我收到此错误:

致命错误:在...中的非对象上调用成员函数bind_param()

这是代码:

global $mysqli;
$stmt = $mysqli->prepare("SELECT id, description FROM tbl_page_answer_category WHERE cur_own_id = ?");
$stmt->bind_param('i', $cur_id);
$stmt->execute();
$stmt->bind_result($uid, $desc);

为了检查我的查询,我试图通过控制面板phpMyAdmin执行查询,结果是OK.

我一直在讨论这个MySQL查询.

假设我有这个:

    $add = "INSERT INTO books (title) VALUES(?)";
    if ($stmt = $mysqli->prepare($add)) {

        $arr = array($title);

        foreach ($arr as $value) {
            echo var_dump($value);
        }

        $stmt->bind_param("s", $title);

有了foreach- > var_dump:

string 'Medieval Times (History)' (length=24)
int 1422843281
int 1420844341
string '127.0.0.1' (length=9)
string 'MY_EMAIL@gmail.com' (length=22)
string '' (length=0)
int 1420844805
int 6
int 3
int 1
int 0
int 0
int 1
int 1
int 1
int 1

好吧,当它到达这一行时它会停止并且我收到此错误:

Fatal error: Call to a member function bind_param() …
