How to make the link 'index.php?x' display x section on a page
Question
I was trying to make a site with different parts which will be shown with a questionmark (like index.php?notes, index.php?options, etc.). Normally I see this often on search query pages or blogs (with an ?q="question").
On my index.php page i have set multiple sections that will be shown if the user presses a href link.
I know that this can be done with the anchor link in css (with #options), but since I am using php, I would like to try that.
This is my code at the moment:
<body>
<p>
[<a href="?notes">Notes</a>]
[<a href="?categories">Categories</a>]
[<a href="?options">Options</a>]
</p>
<?php
if($display == 'categories') {
echo "<h4>Categories</h4>";
} else if ($display == "notes") {
echo "<h4>Delete Notes</h4>";
} else {
echo "<h4>Options</h4>";
}
?>
</body>

When using ?q=question you can access it in PHP via $_GET['q'] . In your case, since you don't have q set, but ?notes you need to access it via $_GET['notes'] . Try this:
<?php
if (isset($_GET['categories'])) {
echo "<h4>Categories</h4>";
} elseif (isset($_GET['notes'])) {
echo "<h4>Delete Notes</h4>";
} else {
echo "<h4>Options</h4>";
}

You could set a GET variable p and read that; eg
<a href="?p=notes">notes</a> and in PHP $_GET['p']

if you don't want to use any keys, then you can use this code:
if(isset($_GET)){
$page = key($_GET);
}
But this solution is not very good it can mess your code later. I suggest to use with key ie ?p=notes
