<?php 
//include the information needed for the connection to MySQL data base server. 
// we store here username, database and password 
//include("dbconfig.php");

// to the url parameter are added 4 parameters as described in colModel
// we should get these parameters to construct the needed query
// Since we specify in the options of the grid that we will use a GET method 
// we should use the appropriate command to obtain the parameters. 
// In our case this is $_GET. If we specify that we want to use post 
// we should use $_POST. Maybe the better way is to use $_REQUEST, which
// contain both the GET and POST variables. For more information refer to php documentation.
// Get the requested page. By default grid sets this to 1. 
$page = 1; //$_GET['page']; 

// get how many rows we want to have into the grid - rowNum parameter in the grid 
$limit = 5; //$_GET['rows']; 

// get index row - i.e. user click to sort. At first time sortname parameter -
// after that the index from colModel 
$sidx = 'invid'; //$_GET['sidx']; 

// sorting order - at first time sortorder 
$sord = 'invid' ;//$_GET['sord']; 

// if we not pass at first time index use the first column for the index or what you want
if(!$sidx) $sidx =1; 

// connect to the MySQL database server 
$db = mysql_connect('localhost', user', 'pass') or die("Connection Error: " . mysql_error()); 
$database = 'gridTest';
// select the database 
mysql_select_db($database) or die("Error connecting to db."); 

// calculate the number of rows for the query. We need this for paging the result 
$result = mysql_query("SELECT COUNT(*) AS count FROM invheader"); 
$row = mysql_fetch_array($result,MYSQL_ASSOC); 
$count = $row['count']; 

// calculate the total pages for the query 
if( $count > 0 && $limit > 0) { 
              $total_pages = ceil($count/$limit); 
} else { 
              $total_pages = 0; 
} 

// if for some reasons the requested page is greater than the total 
// set the requested page to total page 
if ($page > $total_pages) $page=$total_pages;

// calculate the starting position of the rows 
$start = $limit*$page - $limit;

// if for some reasons start position is negative set it to 0 
// typical case is that the user type 0 for the requested page 
if($start <0) $start = 0; 

// the actual query for the grid data 
$SQL = "SELECT invid, invdate, amount, tax,total, note FROM invheader ORDER BY $sidx , $sord LIMIT $start , $limit"; 
$result = mysql_query( $SQL ) or die("Couldn't execute query.".mysql_error()); 

// we should set the appropriate header information. Do not forget this.
header("Content-type: text/xml;charset=utf-8");

$s = "<?xml version='1.0' encoding='utf-8'?>";
$s .=  "<rows><br>";
$s .= "<page>".$page."</page>";
$s .= "<total>".$total_pages."</total>";
$s .= "<records>".$count."</records>";

// be sure to put text data in CDATA
while($row = mysql_fetch_array($result,MYSQL_ASSOC)) {
    $s .= "<row id='". $row['invid']."'>";            
    $s .= "<cell>". $row['invid']."</cell>";
    $s .= "<cell>". $row['invdate']."</cell>";
    $s .= "<cell>". $row['amount']."</cell>";
    $s .= "<cell>". $row['tax']."</cell>";
    $s .= "<cell>". $row['total']."</cell>";
    $s .= "<cell><![CDATA[". $row['note']."]]></cell>";
    $s .= "</row>";
}
$s .= "</rows>"; 

echo $s;
?>

and here is the error :

XML Parsing Error: junk after document element
Location: http://localhost/SpDatabase/res/grid/

Line Number 62, Column 1:<?xml version='1.0' encoding='utf-8'?><rows><br><page>1</page><total>1</total><records>1</records><row id='1'><cell>1</cell><cell>2001-01-10</cell><cell>103.00</cell><cell>45.00</cell><cell>149.00</cell><cell><![CDATA[This is record 1]]></cell></row></rows>
