Question

我正在使用CodeIgniter备份数据库实用程序类。但它给了我一个错误

您正在使用的数据库平台不支持的功能。

文件名：E：\ xampp \ htdocs \ zafarsir \ system \ database \ drivers \ mysqli \ mysqli_utility.php

行号：82

这是我的代码

$this->load->dbutil();

        // // Backup your entire database and assign it to a variable
        $backup =& $this->dbutil->backup();


        // Load the file helper and write the file to your server
        $this->load->helper('file');
        write_file('http://localhost/zafarsir/database/mybackup.gz', $backup);

        // Load the download helper and send the file to your desktop
        $this->load->helper('download');
        force_download('mybackup.gz', $backup); 

        $prefs = array(
                        'tables'      => array('user', 'party'),  // Array of tables to backup.
                        'ignore'      => array(),           // List of tables to omit from the backup
                        'format'      => 'txt',             // gzip, zip, txt
                        'filename'    => 'mybackup.sql',    // File name - NEEDED ONLY WITH ZIP FILES
                        'add_drop'    => TRUE,              // Whether to add DROP TABLE statements to backup file
                        'add_insert'  => TRUE,              // Whether to add INSERT data to backup file
                        'newline'     => "\n"               // Newline character used in backup file
                      );

        $this->dbutil->backup($prefs);

这条线给我错误

$backup =& $this->dbutil->backup();

function backup_Eventtable() {
    $this->load->dbutil();
    $prefs = array(
            //'tables'      => array('hotel_accomodation'),  // Array of tables to backup.
            'ignore'      => array(),           // List of tables to omit from the backup
            'format'      => 'txt',             // gzip, zip, txt
            'filename'    => ''.date("Y-m-d-H-i-s").'-mybackup.sql',    // File name - NEEDED ONLY WITH ZIP FILES
            'add_drop'    => TRUE,              // Whether to add DROP TABLE statements to backup file
            'add_insert'  => TRUE,              // Whether to add INSERT data to backup file
            'newline'     => "\n"               // Newline character used in backup file
          );

    $backup =& $this->dbutil->backup($prefs);
    //I tried it with and without the next 2 Lines.
    $this->load->helper('file');
    write_file('backup_db/'.date("Y-m-d-H-i-s").'-mybackup.sql', $backup); 
}

试试这段代码，可能会有用....
