Question

我有一个使用预定义的mssql连接调用mssql存储过程的函数。基础是我有一个类来执行与mssql数据库的连接，并将该连接分配给变量。这个类中有另一个函数，然后调用一个单独的类（我在下面包含了这个单独的类）。然后，该类定义mssql变量以传递连接，以便它可用于几个存储过程。

此类'IssueCertificate'中的第一个函数正常工作并且存储过程运行正常，此函数然后调用另一个名为PrintCertificate的类中的函数，此函数然后调用另一个失败的存储过程。我已经尝试过这个函数作为一个独立的类外部，它运行正常所以这里没有问题，但由于某些原因，当它作为另一个函数的一部分运行时，它失败了。请参阅下面的课程：

$_SERVER['DOCUMENT_ROOT'] = str_replace('\\','/',substr($_SERVER['SCRIPT_FILENAME'], 0, 
0-strlen($_SERVER['PHP_SELF'])));
define("BASEURL", $_SERVER['DOCUMENT_ROOT']);

require_once(BASEURL."/api/db.php");
require_once(BASEURL."/api/adodb/adodb.inc.php");
require_once(BASEURL."/api/functions.php");

class CertificatesDirectAPI {

    var $data = '';

    function __construct($data, $config) {

              $this->data['Request'] = $data;

              // create connection to the database
              $this->db = ADONewConnection('mysql');

              // if connection failed, send error response xml, otherwise continue processing
              if (!$this->db->connect($config['db']['hostname'],$config['db']['username'],$config['db']['password'],$config['db']['database'])) {
                $this->db->close();
                exit();
              }

              $this->msdb = mssql_connect('server','user','password');
              mssql_select_db('database');

              $this->db->SetFetchMode(ADODB_FETCH_ASSOC);
              $this->process();
    }

    // process the request
    private function process() {
          $output = $this->PrintCertificate();
    }


    private function PrintCertificate(){

        //get supplier info
        $installer = new UserInformation($this->msdb);
        $supplier = $installer->GetInstallerDetails($this->data['Request']['installer_id']);

        //create new instance and print
        $cert = new PrintCert($this->msdb);
        $response = $cert->IssueCertificate($this->data,$supplier);
    }
}

$api = new CertificatesDirectAPI($_REQUEST, $config);

class PrintCert {

    public $msdb;

    function __construct($msdb){
        //assign class wide vars to object
        $this->msdb = $msdb;
    }

    public function IssueCertificate($data, $supplier){

$return = $this->PrintCertificate("1279441", $supplier);

        return $return;
    }

    private function PrintCertificate($certNumber, $supplier){
        //initiate function
        $proc = mssql_init('usp_Return_Certificate_Details', $this->msdb); 

        mssql_bind($proc, '@Certificate_Number', $certNumber, SQLINT4, false, false, 10);

        //Execute Procedure 
        $result = mssql_execute($proc); 

        while ($row = mssql_fetch_assoc($result)){
            $results[] = $row;    
            }
        $return = $results;
        //print_r($return);
        $pdf = $this->BuildPdf($return[0], $supplier);

        //Free Memory 
        mssql_free_statement($proc); 

        return $pdf;
    }
}

返回的错误消息如下：

Warning: mssql_execute() [function.mssql-execute]: stored procedure execution failed in /home/ssaibuk/public_html/api/modules/print.class.php on line 131

Warning: mssql_fetch_assoc() expects parameter 1 to be resource, boolean given in /home/ssaibuk/public_html/api/modules/print.class.php on line 133

如果这里有足够的东西让我知道，我可以添加更多。

使用mssql_init时，无法访问$ this内的变量
