分析错误:语法错误，意外的T_ELSE，第54行/home/petit/public_html/system/datab

我已经从一个服务器到另一个服务器进行了opencart传输，我得到了以下错误分析错误：语法错误，意外的T_ELSE，第54行上/home/petit/public_html/system/database/mysqli.php中应为T_FUNCTION

当我尝试访问我的网站或管理员页面时。知道为什么会发生这种事吗？我已经一步一步地遵循了程序。

这是mysqli.php

 <?php
final class MySQLi {
    private $mysqli;
    public function __construct($hostname, $username, $password, $database) {
        $this->mysqli = new mysqli($hostname, $username, $password, $database);
        if ($this->mysqli->connect_error) {
            trigger_error('Error: Could not make a database link (' . $this->mysqli->connect_errno . ') ' . $this->mysqli->connect_error);
        }
        $this->mysqli->query("SET NAMES 'utf8'");
        $this->mysqli->query("SET CHARACTER SET utf8");
        $this->mysqli->query("SET CHARACTER_SET_CONNECTION=utf8");
        $this->mysqli->query("SET SQL_MODE = ''");
    }
    public function query($sql) {
        $result = $this->mysqli->query($sql);

        if ($this->mysqli->errno) {
        //$mysqli->errno
        }
            if (is_resource($resource)) {
                $i = 0;
                $data = array();
                while ($row = $result->fetch_object()) {
                    $data[$i] = $row;
                    $i++;
                }
                $result->close();
                $query = new stdClass();
                $query->row = isset($data[0]) ? $data[0] : array();
                $query->rows = $data;
                $query->num_rows = $result->num_rows;
                unset($data);


                return $query;  
            } else {
                return true;
            }
        } else {
            trigger_error('Error: ' . mysql_error($this->link) . '<br />Error No: ' . mysql_errno($this->link) . '<br />' . $sql);
            exit();
        }
    }
    public function escape($value) {
        return $this->mysqli->real_escape_string($value);
    }
    public function countAffected() {
        return $this->mysqli->affected_rows;
    }
    public function getLastId() {
        return $this->mysqli->insert_id;
    }   
    public function __destruct() {
        $this->mysqli->close();
    }
}
?>

提前感谢
