OpenUnix - to BSD or not to BSD

Web development: PHP

To start and close a php script:

<?php
echo "here is the html code";
>

To split website to dynamically editable parts:
<?php include ("website_parts/header.php")>
<?php include ("website_parts/left_menu.php")>
here comes the html code
<?php include ("website_parts/bottom.php")>

Session Management in three scripts:

login.php

<?php
echo '<form name="frmUser" method="post" action="login_check.php">';
echo '<table align="left">';
echo '<td align="right">login</td>';
echo '<td><input type="text" name="myusername"></td>';
echo '</tr>';
echo '<td align="right">heslo</td>';
echo '<td><input type="password" name="mypassword"></td>';
echo '</tr>';
echo '<td></td><td><input type="submit" name="submit" value="Přihlásit"></td>';
echo '</tr>';
echo '</table>';
?>

login_check.php

<?php
session_start();
$message="";
if(count($_POST)>0) {

	require "./conf/connect.php";
	$myusername=$_POST['myusername'];
	$mypassword=$_POST['mypassword'];
	$myusername = mysql_escape_string($myusername);
	$mypassword = mysql_escape_string($mypassword);
	
 if ($result = $spojeni->query("SELECT * FROM autori WHERE login='$myusername' and heslo=encrypt('$mypassword',heslo)"))
 {
 	if ($result->num_rows == 1)
	{
              while ($row = $result->fetch_object())
                   {
 		// Register session
	       $_SESSION["user_id"] = $row->id;
               $_SESSION["user_login"] = $row->login;
               $_SESSION["user_jmeno"] = $row->jmeno;
	       echo "Přihlášení úspěšné.";
               header("Refresh:0; URL=./index.php");
		   }
	       }
      else {
	$_SESSION['errors'] = "Ne, ne, ne. Tak to není... Bude to někde mezi židlí a klávesnicí...";

	         echo $_SESSION['errors'];
                 header("Refresh:0; URL=./index.php");
           } 
  }
  }
//if(isset($_SESSION["user_id"])) {
//	header("Location:index.php");
//}
?>
