"Error: could not find driver" triggers "Fatal error: Uncaught Error: Call to a member function prepare() on null"

Question

基本上，当我尝试加载页面时，确切的错误消息如下：

Error: could not find driver
Fatal error: Uncaught Error: Call to a member function prepare() on null in /var/www/vhosts/FileA.php:46 Stack trace: #0 /var/www/vhosts/FileB.php(120): Database4->numofrows('select a.cardco...') #1 {main} thrown in /var/www/vhosts/FileA.php:46 on `line 46`

所以我转到有问题的 FileA.php 文件并按照他们上面所说的那样转到第 46 行。

FileA.php

<?php
    ini_set('max_execution_time',3600);
    Class Database4{
        protected $username;
        protected $password;
        protected $server;
        protected $dbName;
        public $conn;

        public function __construct(){
            $this->connection();
        }
        public function __destruct(){
            $this->conn=null;
        }
        protected function connection(){
            try{
                $this->username='dummyUser';
                $this->password='dummyPass';
                $this->server='192.168.0.42';
                $this->dbName='dummyDatabase';
                $this->conn=new PDO('dblib:host='.$this->server.':1433;dbname='.$this->dbName, $this->username, $this->password);

           } catch (PDOException $e){echo "Error: ".$e->getMessage();
       }
    }

            public function insert($sqlInsert)
    {
        $stmt=$this->conn->prepare($sqlInsert);
        $stmt->execute();
        return $stmt;
    }

    public function update($sqlUpdate){
        $stmt=$this->conn->prepare($sqlUpdate);
        $stmt->execute();
        return $stmt;
    }
    public function delete($sqlDelete){
        $stmt=$this->conn->prepare($sqlDelete);
        $stmt->execute();
        return $stmt;
    }
    public function select($sqlSelect){ 
        $stmt=$this->conn->prepare($sqlSelect);
        $stmt->execute();
        return $stmt;
    }
    public function numofrows($sql){
        $stmt=$this->conn->prepare($sql);
        $stmt->execute();
        $numofrows= count($stmt->fetchAll());
        return $numofrows;
    }
}
?>

查看代码后，似乎有大量答案说问题可能位于 FileA.php 的 line 22 上，我需要检查是否有 pdo_mysql已安装。

为了检查，我去看了看 /etc/php.ini 这是我设法在其中找到的内容。

extension=php_pdo_mysql.dll;
extension=php_pdo.dll;
extension=pdo.so;
extension=pdo_mysql.so;

郁闷了，去看一看FileB.php此时心情失落

我用 php -v 转换成美分 OS 我得到了：

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/libr64/php/modules/php_pdo_mysql.dll' - /usr/lib64/php/modules/php_pdo_mysql.dll: cannot open shared object file: No such file or directory in line 0

我尝试了以下操作（没有成功——已安装消息）：

yum install php-pdo
yum install php-pdo_mysql

在运行 mysql -V 我得到：

mysql Ver 15.1 Distrib 10.1.36-MariaDB, for Linux (x86_64) using readline 5.1

任何有建设性的东西都会很有帮助，因为这个持续存在的问题让我困惑了几个星期。此代码没有注释或文档，因为制作此代码的人已无法联系到。

请检查您的主机是否安装了 mssql ext，因为您正在尝试使用 FileA.php

连接到 mssql 服务器

对不起我的英语

Answer 2

我决定联系 OpenCart 支持以远程进入我的网络并让他们通过我们的文件系统和 Cent OS 终端进行操作。我不得不通过即时通讯工具共享我的屏幕，并让他们在我的监督下获得远程访问权限。

看起来他们知道要执行的正确扩展和正确的后续命令。

yum -y install mssql-server
cd /tmp/
mysql -u root -p website_com
mysql -u root -p website_com < oc.sql
mysql -u root -p website_com
shutdown -h +300
