Get ul li a string values and store them in a variable or array php

I'm trying to store the string values of a list item on my website into a variable/array in PHP to do some conditional checks/statements with them. I am having a bit of difficulty getting the list item's string value using PHP. Can anybody help?

This is the markup.

<div class="coursesListed">
<ul>
<li><a href="#"><h3>Item one</h3></a></li>
<li><a href="#"><h3>item two</h3></a></li>
<li><a href="#"><h3>Item three</h3></a></li>            
</ul>
</div>

What I want ideally is either a variable or array that holds the values "Item one", "Item two", "Item three".

It might be easier to parse it in Javascript (perhaps using jQuery), and then send it to your PHP with some AJAX. 

// Javascript/jQuery
var array = [];
$("h3").each(function() {
    array.push($(this).html());
});

var message = JSON.stringify(array);
$.post('test.php', {data: message}, function(data) {
    document.write(data); // "success"
}

Then in PHP:

<?php

$data = $_POST['data'];

// convert json into array
$array = json_decode($data);

// do stuff with your data
// then send back whatever you need

echo "success";

?>

Try this

$html = '<div class="coursesListed">
<ul>
<li><a href="#"><h3>Item one</h3></a></li>
<li><a href="#"><h3>item two</h3></a></li>
<li><a href="#"><h3>Item three</h3></a></li>            
</ul>
</div>';

$doc = new DOMDocument();
$doc->loadHTML($html);
$liList = $doc->getElementsByTagName('li');
$liValues = array();
foreach ($liList as $li) {
    $liValues[] = $li->nodeValue;
}

var_dump($liValues);

You will need to parse the HTML code get the text out. DOM parser can be used for this purpose.

   $DOM = new DOMDocument;
   $DOM->loadHTML($str); // $str is your HTML code as a string

   //get all H3 
   $items = $DOM->getElementsByTagName('h3');
