I understand this question has likely been asked before, but nothing is simple, straightforward, and to the point for a beginning php or ajax/jquery programmer. The problem is identifying which link has been clicked on one html/php page, and then pulling up a different php page accordingly. In other words, what is the best way to send a string from one php file to another, without using forms?

$_GET is pretty straightforward:
page_a.php:
<a href="page_b.php?bar=foo">link</a>
page_b.php
Hey, I got "<?php echo $_GET['bar']; ?>" from page a !
Which would display:
Hey, I got "foo" from page a !
Note that you should test if the variable has been set:
<?php
if (isset($_GET['bar'])) {
echo $_GET['bar'];
}
?>
If you want to pass more variables, add a & and append them to the url:
page_a.php?var1=text1&var2=text2&var3=...
And you retrieve them the exact same way (still, you want to check everything before, I didn't do it for readability):
<?php
$var1 = $_GET['var1']; // = text1
$var2 = $_GET['var2']; // = text2
$var3 = $_GET['var3']; // = ...
?>

$_SESSION variables can store information that can used all over the website.
Although as I read this:
The problem is identifying which link has been clicked on one html/php page, and then pulling up a different php page accordingly
This sounds like a hyperlink?

The php file I link to pulls in a different php file according to the link clicked in the original file (so three files total). All hyperlinks in the original file are pointing to the intermediary php file.

Yeah you can use GET or Session Variables, either of them will keep track of whatever value you wish to pass to the middle man.
ajaxand jquery ajax does it better.
