错误：查询：资源ID＃4

Question

工作到我FPDF从MySQL转换为SQL-Server，但得到这个错误：

Error: 
Query: Resource id #4 

在我的代码我从MYSQL改变了这一切，以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'])) 

{

{

{ 
    //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您的Table（）方法。

这是方法需要什么，查询和属性的数组：

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

这是你的过客，一个连接实例和查询。

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

尝试上述更改为，

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