Question

**我正在使用PHP和SQL-SERVER ..我的连接字符串没问题，但是当我尝试取一些东西时，我们说（一列），当我print_r()时，它只返回列名和数据，它显示符号。我也使用

生成带有空值的JSON输出

以下php脚本**

我的连接文件

<?php
    class odbcConnection
{
    public $myServer = "SMS-HP\MSSQL";
    public $myUser = "sa";
    public $myPass = "123456";
    public $myDB = "procurementdb";
    public $connDB;

    // function to connection to the database 
    public function connectionDB(){

        // check wheather the given function exists 
        if(function_exists(odbc_connect))
        {

            $this->connDB = odbc_connect("Driver={SQL Server Native Client 10.0};Server=$this->myServer;Database=$this->myDB;", $this->myUser, $this->myPass);
            //echo("Connection Established <br>");
        }
        else
        {
            die("Connection Failed".odbc_errormsg());
        }

    }

    // function to closing the connection
    public function closeConnection()
    {
        odbc_close($this->connDB);
    }

}//End of class

//$conn = new odbcConnection();
//$conn->connectionDB();

  ?>

加载存储类文件

<?php
include("dbConnection.php");
class LoadStorageData extends odbcConnection
{
    public function LoadStorageData()
    {
        $this->connectionDB();
    }
    public function LoadData()
    {

        $sql ="select NameOfStorage from tblStaff where DivisionID=7 and DistrictID=1 order by NameOfStorage;";

        $result = odbc_exec($this->connDB,$sql);
        $dataSet = array();
        while($rows = odbc_fetch_array($result))
        {
            array_push($dataSet,$rows);
            echo("<pre>");
            print_r($rows);
            echo("</pre>");
        }

        if($dataSet){
            json_encode($dataSet);
            return json_encode($dataSet);
        }
        else{
            echo "error";
            return false;
        }

    }

}

$json = new LoadStorageData();
echo $json->LoadData();
$json->closeConnection();

＆GT;

*的输出 *

Array
(
    [NameOfStorage] => þÎý
)

Array
(
    [NameOfStorage] => þÎ
)

Array
(
    [NameOfStorage] => þÎýÎ
)

Array
(
    [NameOfStorage] => þÎýÎ
)

Array
(
    [NameOfStorage] => þÎýÎ
)

Array
(
    [NameOfStorage] => þÎýÎ
)

Array
(
    [NameOfStorage] => þÎýÎ
)

[{"NameOfStorage":null},{"NameOfStorage":null},{"NameOfStorage":null},{"NameOfStorage":null},{"NameOfStorage":null},{"NameOfStorage":null},{"NameOfStorage":null}]

**对此有任何帮助表示赞赏....

谢谢...... **

Answer 1

看起来你在“NameOfStorage”字段中有二进制数据，你可以在推送JSON中的值之前使用base64_encode（）函数进行编码，并查看数据是否在数组中打印。

Answer 2

或许使用mb_convert_encoding()很有用。 link
