Hi

I know asp to some extent and php nothing. I want a session script in php. Could anybody help me?

In ASP the code works like this.

Code: Select all

<%
Session("session_name") = "123"
%>

<%
If Session("session_name") = "123" Then
%>
Execute these HTML codes.
<%
Else
%>
Execute these false HTML codes.
<%
End If
%>

I want a code in php. Please help.

Code: Select all

<?php
session_start();
$sessionname = "123";
session_register('sessionname');
?>

<?php
if($_SESSION[sessionname] = "123")
{
?>
Execute these HTML codes.
<?php
}else{
?>
Execute these false HTML codes.
<?php
}
?>

That's my closest guess, i haven't used PHP in awhile.

If you can please remodify this in php. Please do the same.

index.asp

<html>
<head>
<title>Check ASP</title>
</head>
<body link=#0000FF alink=#0000FF vlink=#0000FF text=#000000 bgcolor=#ffffff>
<font face=tahoma size=3>
<%
If Session("mysite") <> "me" Then
%>
Not Me, [url=login.asp]Change[/url]
<%
Else
%>
Me, [url=logout.asp]Change[/url]
<%
End If

index.php

Code: Select all

<?$mysite=$_SESSION["mysite"];?>
<html>
<head>
<title>Check ASP</title>
</head>
<body link=#0000FF alink=#0000FF vlink=#0000FF text=#000000 bgcolor=#ffffff>
<font face=tahoma size=3>

<? 
If ($mysite != "me" )
	echo "[url=login.asp]Change[/url]";
else
	echo "[url=logout.asp]Change[/url]";
?>

</font>
</body>
</html>

login.php

Code: Select all

<?
	session_start();
	$_SESSION["mysite"] = "me";

// header must be before any output, it would be best if u use separate file for sesion registration, like here- only session registration and redirection
	Header(location:index.php);
?>

logout.php

Code: Select all

<?
	session_destroy();
	header("location: index.php");
?>

Try this, it should be ok. If somthing will not work, paste here and error

The same code, with this result in index.php.

Parse error: parse error, unexpected T_STRING, expecting ',' or ';' in c:\Inetpub\www\phplogin\index.php on line 11

I changed the code of index.php to

Code: Select all

<?$mysite=$_SESSION["mysite"];?> 
<html> 
<head> 
<title>Check ASP</title> 
</head> 
<body link=#0000FF alink=#0000FF vlink=#0000FF text=#000000 bgcolor=#ffffff> 
<font face=tahoma size=3> 

<? 
If ($mysite != "me" ) 
   echo "[url=login.php]Login[/url]"; 
else 
   echo "[url=logout.php]Logout[/url]"; 
?> 

</font> 
</body> 
</html>

Then the error was:

Parse error: parse error, unexpected ':' in c:\Inetpub\www\phplogin\login.php on line 6
