Question

继续将我的fpdf从MYSQL转换为SQL-Server，但收到此错误：

Error: 
Query: Resource id #4

在我的代码中，我将所有内容从MYSQL更改为sqlsrv：

生成-pdf.php

<form action='' method='Post'/>

<input type='submit' name='submit' value='Generer rapport'>

</form>



<?php

require('mysql_table.php');

 $timezone = "Europe/Oslo";
 date_default_timezone_set($timezone);
 $format="%H%M%S";
$strf=strftime($format);

 if(isset($_POST['submit']))

{


class PDF extends PDF_MySQL_Table
{


function Header()
{
    //Title
    $this->SetFont('Arial','',18);
    $this->Cell(0,6,'Measurement',0,1,'C');
    $this->Ln(10);
    //Ensure table header is output
    parent::Header();
}
}

//Connect to database
$conn_array = array (
"UID" => "sa",
"PWD" => "root",
"Database" => "chart",
) ;
$conn = sqlsrv_connect('BILAL' , $conn_array);


$pdf=new PDF();
$pdf->AddPage();
//First table: put all columns automatically
$pdf->Table($conn, "SELECT PH, Temperature FROM chartgoogle");

您将错误的参数传递给Table（）方法。

这是方法所期望的，查询和属性数组：

Table($query,$prop=array())

这是您的传递，连接实例和查询。

$pdf->Table($conn, "SELECT PH, Temperature FROM chartgoogle");

尝试将上方更改为，

$pdf->Table("SELECT PH, Temperature FROM chartgoogle");

错误：查询：资源ID＃4
