[PHP-WIN] RE: Is this possible? --> Correction

[Carlos Andre Marques Moreira]

Someone show me this error on the code below
Someone showmed a error, then i'll sending it again.

1: To execute php code when a A HREF link is clicked.

One way to do this is:
// This will check what link was clicked
<?php
switch ($link){
 case 1: // link 1 was clicked
// write your code here
  break;
 case 2: // link 2 was clicked
// write your code here  break;
 default: // First time entering the page, no link clicked
// write your code here
}
?>
// Here are the links
<a href=<?php echo $PHP_SELF."?link=1"; ?>> link 1 </a>
<a href=<?php echo $PHP_SELF."?link=2"; ?>> link 2 </a>

Instead of (this code has a mistake)
// Here are the links
<a href=<?php echo $PHP_SELF."?$link=1"; ?>> link 1 </a>
<a href=<?php echo $PHP_SELF."?$link=2"; ?>> link 2 </a>

Using PHP 404pl1 / MySQL 3.23.35 / PWS / W98SE if anybody should need to
know...
The stuff is for an intranet application.

1: To execute php code when a A HREF link is clicked.

I have the need to change a session variable depending on which link (of
a couple) that is clicked. The link is supposed to call $PHP_SELF which
then change its output depending on the value of the session variable.
I know that i can solve it by letting the link call different php
scripts - which update the session variable and then call back to the
first page.
If there is another way ( javascript maybe?), i am interested to know
about it.

2: To have one undo step on a database update.

Do anybody know / seen any example / tutorial on how this kind of
function can be implemented?
Let me know!
I have read most of the stuff at Newbie network, PHPdeveloper,
PHPeverywhere, Zend, Devshed, Webmonkey and PHPbuilder - but i have
never come across anything like this.
