<?php



        $date = date("Y-m-d"); 
        $hodina = date('H:m');    
        $datum1 = strtotime($date);
        $datum2 = date("l", $datum1);
        $datum3 = strtolower($datum2);  // zmenit na lowercase
       
             
$con = mysql_connect("localhost","user","password");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("system", $con);

mysql_query("UPDATE tabulka_casoc SET data_koniec='$hodina' WHERE data_den='$datum3'");

mysql_close($con);
