//echo 'oo'; 
exit(); 
} 
$db=new db(); 
$str=''; 
$sql="select * from user where deptID=10 and status='On' and worksheet like '%$ws%' order by worksheet"; 
$rt=$db->rtAssoc($sql); 
while($row=array_shift($rt)){ 
$str.="<a href="\" href="\""#\" onclick=\"end('" 
.$row['emp_name'].':'.$row['emp_worksheet']."');\">" 
.$row['emp_name'].':'.$row['emp_worksheet']

$str=substr($str,0,-6); 
echo trim($str);
