	  	//
		function paging_total_pages($total_rows, $rows_per_page) {
		
			return ceil($total_rows / $rows_per_page);
			
		}
		//
	  	$current_page = 1;
		if(isset($_GET['page'])){
			$current_page = $_GET['page'];
		}
		$row_per_page = 10;
		$start_row = ($current_page - 1) * $row_per_page;
		
		include("_ssh/portal/manage/config.inc.php");
		$sql = "SELECT * FROM channel Order by id Desc LIMIT $start_row, $row_per_page";
		
		$result = mysql_query($sql);
		
		while($dbarr = mysql_fetch_array($result)) 
		{
      ?><div style="padding-top:5px;"></div>
