$newdateformat = date("d_m_y");

$ttaerr="";

mysql_select_db($mysql_database,$bd);

$se_sql=mysql_query("select * from $newdateformat where S_No='$login_sess' ");

 

$row=mysql_fetch_array($se_sql);

$name=$row['S_Name'];

1 - use the code tags as described in the forum's rules.  They are the little <> icon in the editor menu or simply code and /code wrapped in brackets.

 

2 - you can't compare a string (which $end is) to a date value (which $now is).  Try:

$end = strtotime('04:15:00 PM');

3 - your table names are dates?  Really?

 

There may be more but those two things are a start
