Changing links by priority - PHP / HTML - php

Question

I am currently working on a school project and appreciate your help.
HTML Code:
LINK 1
LINK 2
LINK 3
Now as I am relatively new to PHP, I need clue wehere to start or which topics are relevant for my solution. I have already searched the Forum here and with google, but unforutenly, didn't find anything, that fits my needs.
What I need, is a PHP-Code, that contains 6 href Links and every Link has a priority. So every time somebody clicks on "LINK 1" on the html file, he gets directed to the PHP-File "change-1.php", where one of the six href Links get activated.
PHP CODE "change-1.php":
<?php
if (condition) {
echo "http://www.someotherwebsite-1.com";
}
elseif (condition) {
echo "http://www.someotherwebsite-2.com";
}
elseif (condition) {
echo "http://www.someotherwebsite-3.com";
}
elseif (condition) {
echo "http://www.someotherwebsite-4.com";
}
elseif (condition) {
echo "http://www.someotherwebsite-5.com";
}
elseif (condition) {
echo "http://www.someotherwebsite-6.com";
}
?>

Perhaps this should help
LINK 1
LINK 2
LINK 3
Just create one change.php file
//to get change
<?php
if ($_GET['change'] == 1) {
echo "http://www.someotherwebsite-1.com";
}
elseif ($_GET['change'] == 2) {
echo "http://www.someotherwebsite-2.com";
}
elseif ($_GET['change'] == 3) {
echo "http://www.someotherwebsite-3.com";
}
elseif ($_GET['change'] == 4) {
echo "http://www.someotherwebsite-4.com";
}
elseif ($_GET['change'] == 5) {
echo "http://www.someotherwebsite-5.com";
}
elseif ($_GET['change'] == 6) {
echo "http://www.someotherwebsite-6.com";
}
?>
Now this is the basic idea. You can manipulate the data however you want.
I hope you got the concept.
