[PHP]
<?php 
$str = "<font class=\"success\"> Member Area</font>";
if($login == "error") {
 $str = "<font  face=verdana color=red><b>LOGIN ERROR!: </font><font color=black>Wrong Username Or Password</b></font>";
}
elseif($login == "blocked") {
 $str = "<font  face=verdana color=red><b>YOUR ACCESS HAS BEEN BLOCKED!</b></font>";
}
elseif($login == "session") {
 $str = "<font  face=verdana color=red><b>SESSION ERROR!: <font color=black>User Already Connected. Please Logout First</font></b></font></center>";
}
elseif($login == "") {
}
elseif($login == "logout") 
{
 $str = "<font class=\"success\">User <font color=blue>$User_Login</font> Logged Out</font>";
   }
