Is there any function that can take a user to another link. For example.......

PHP Code:


			
if($ax="1")

{ thefunction(thelink1) };

else

{ thefunction(thelink2) };

secondly, does "=>" in

PHP Code:


			
$key => $value

means 'equal or bigger than'?

lastly, whats the different between '$$key' and '$key'?

1/ Header

2/ No

PHP Code:


			
 $key >= $value

is greater than or equal to

PHP Code:


			
$key => $value

is an associative array assignment array

3/ Variable variable

waller, this can be done if you have not yet sent any content to the client (includes blank lines, any HTML, print statements, etc). Use the header() function.

PHP Code:


			




$ax = $_GET[somevar];



if( $ax = 1 )

{

    header("Location:  http://www.somewhere.com" );

}

else

{

    header( "Location:  http://somewhere-else.com" );

}

This will work. What will not work is if you have any blank lines or content before the call to the header() function.

Thanks....I have another one.
How can we display a page only for a period of time.
For example.....(index.php) go to (premain.php[wait 3 second]) go to (main.php).
After I login from "index.php" I just want to display the "premain.php" page for 3 seconds and then it automatically go to "main.php" after that. Any existing function that can do that?

The problem has nothing to do with php. Look at <meta http-equiv="Refresh"> in HTML. After you gave the page to the browser you cannot manipulate it.

Here's a very simple example. This uses an absolute URL (full qualified), but you could use just premain.php as the URL value.

HTML Code:

<HTML>
<HEAD>
<TITLE>redirect</TITLE>
<META HTTP-EQUIV="refresh" CONTENT="10;URL=http://www.bobsworld.com">
</HEAD>
<BODY>
You are about to be redirected in 10 seconds to <a href="http://www.bobsworld.com">Bob's World</a></BODY>
</HTML>
