Hi I have to place the waiting image as the script take to 15 - 20 second to executes here is the code

session_start();
 $exceptionxlsx_array = array();
 $exceptionxlsx_array = $_SESSION['exceptionxlsx_array'];

 include("impfun.php");
 require ('dbconfig.php');
 include("pdf.php");
 $objimp = new impfun;
 if(!empty($exceptionxlsx_array)){
    $exception_filename = 'admin/OccurException/existexception.xlsx';
    $objimp->makexlsxfile($exceptionxlsx_array,$exception_filename);
 }
 $filename = $_SERVER["DOCUMENT_ROOT"]."/bi_tracker/admin/OccurException/"; 
				$objimp->Zip($filename, './OccurException.zip');
				$filename='OccurException.zip';
				$objimp->truncate();
				$objimp->delete_file();

			//ob_end_clean();
			//ob_end_flush();
			//ob_flush();
			//header_remove();
			header("Pragma: public");
			header("Expires: 0");
			header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
			header("Content-Type: application/force-download");
			header( "Content-Disposition: attachment; filename=".$filename);

 session_start();
 $exceptionxlsx_array = array();
 $exceptionxlsx_array = $_SESSION['exceptionxlsx_array'];

 include("impfun.php");
 require ('dbconfig.php');
 include("pdf.php");
 $objimp = new impfun;
 if(!empty($exceptionxlsx_array)){
    $exception_filename = 'admin/OccurException/existexception.xlsx';
    $objimp->makexlsxfile($exceptionxlsx_array,$exception_filename);
 }

 ?>
 <html>
	<body onLoad="init()">
		<div id="loading" style="position:absolute; width:100%; text-align:center; top:300px;">
			<img src="loading.gif" border=0>
		</div>
		<script>
			var ld=(document.all);
			var ns4=document.layers;
			var ns6=document.getElementById&&!document.all;
			var ie4=document.all;
			if (ns4)
			ld=document.loading;
			else if (ns6)
			ld=document.getElementById("loading").style;
			else if (ie4)
			ld=document.all.loading.style;
			function init()
			{
			if(ns4){ld.visibility="hidden";}
			else if (ns6||ie4) ld.display="none";
			}
		</script>
	</body>
</html>	

 <?php 


 $filename = $_SERVER["DOCUMENT_ROOT"]."/bi_tracker/admin/OccurException/"; 
				$objimp->Zip($filename, './OccurException.zip');
				$filename='OccurException.zip';
				$objimp->truncate();
				$objimp->delete_file();

			//ob_end_clean();
			//ob_end_flush();
			//ob_flush();
			//header_remove();
			header("Pragma: public");
			header("Expires: 0");
			header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
			header("Content-Type: application/force-download");
			header( "Content-Disposition: attachment; filename=".$filename);
			header( "Content-Description: File Transfer");
			readfile($_SERVER["DOCUMENT_ROOT"]."/bi_tracker/OccurException.zip");

If this page is serving the file being downloaded then you don't want it to be serving an HTML page instead. Serve one or serve the other.
