สอบถามเรื่อง XML กับ PHP หน่อยค่ะ พอดีจะดึงข้อมูลจาก base มาโชว์ในไฟล์ xml ค่ะ

echo " <?xml version='1.0' encoding='utf-8' ?> " ;
echo " <banner> " ;
echo " 	<globals
		width='590' height='300' 
		currentItem='0' radius='6'
		showButtons='true' buttonLocation='right'
		blurX='10' blurY='10'
		showContent='true'
		bgColor='#000000' bgAlpha='0.7' bgPaddingBottom='0'
		titleColor='#00CCFF' titleFontSize='28'
		descriptionColor='#FFFFFF' descriptionFontSize='13'
		cssFile='xml_sliding/deploy/css/banner.css'
	> " ;
echo " 		<buttonTitleColor default='#000000' rollOver='#CD0000' current='#FFFFFF'/> " ;
echo " 		<buttonDescriptionColor default='#444444' rollOver='#FF0000' current='#F0F0F0'/> " ;		
echo " 	</globals> " ;
$img="select * from project_img where project_id='$pro_id'";
$result_img=mysql_query($img)or die("SQL ERROR");
while($row_img=mysql_fetch_array($result_img))
{
$img_name=$row_img['image_name'];
$img_button=$row_img['button_title'];
$img_title=$row_img['title'];
$img_detail=$row_img['detail'];

echo " 	<item src='project_img/".$img_name."' transition='y' timer='5'> " ;
echo " 		<buttonTitle><![CDATA".$img_button."]]></buttonTitle> " ;
echo " 		<buttonDescription></buttonDescription> " ;
echo " 		<title><![CDATA[".$img_title."]]></title> " ;
echo " 		<description><![CDATA[".$img_detail."]]></description> " ;
echo " 	</item> ";
}
echo " </banner> ";
