Error: Query: Resource id #4

Question

Working on to convert my fpdf from MYSQL to SQL-Server but getting this error:

Error: 
Query: Resource id #4

In my code I have changed all of from MYSQL to sqlsrv:

generate-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");

You are passing wrong parameters to your Table() method.

This is what the method expects, a query and an array of properties:

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

This is what your passing, a connection instance and a query.

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

Try changing above to,

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