MySQL的get_result替代PHP＆lt; 5.3？

Question

我有一个大问题

public function get_setting($setting) {
    // Prepate statement
    $prepared = $this->prepare("SELECT `val` FROM `filex_settings` WHERE `setting`=?", 'get_setting');
    $this->bind_param($prepared->bind_param('s', $setting), 'get_setting()');
    $this->execute($prepared, 'get_setting()');
    $result = $prepared->get_result();// < 5.3 PHP
    $row = $result->fetch_object();
    return $row->val;
}

替代方案吗？

您可以尝试使用fetch()代替bind_result()。

public function get_setting($setting) {
    // Prepate statement
    $prepared = $this->prepare("SELECT `val` FROM `filex_settings` WHERE `setting`=?", 'get_setting');
    $this->bind_param($prepared->bind_param('s', $setting), 'get_setting()');
    $this->execute($prepared, 'get_setting()');
    $this->bind_result($col_1,$col_2,..)
    while($this->fetch())
    {
        return $col_n // the value which you want
    }  
}
