**我正在使用 PHP 和 SQL-SERVER .. 我的连接字符串没问题，但是当我尝试获取一些东西时，比如说（一列），当我print_r()只返回列名和数据时，它会显示符号。我还使用我正在使用的空值生成 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();
?>
*输出*
