Answer 1

Below code will show you how to get DIV tag's content using PHP code.
PHP Code:
<?php
$content="test.html";
$source=new DOMdocument();
$source->loadHTMLFile($content);
$path=new DOMXpath($source);
$dom=$path->query("*/div[#id='test']");
if (!$dom==0) {
foreach ($dom as $dom) {
print "
The Type of the element is: ". $dom->nodeName. "
<b><pre><code>";
$getContent = $dom->childNodes;
foreach ($getContent as $attr) {
print $attr->nodeValue. "</code></pre></b>";
}
}
}
?>
We are getting DIV tag with ID "test", You can replace it with your desired one.
test.html
<div id="test">This is my content</div>
Output:
The Type of the element is: div
This is my content

Answer 2

You should put the php code into a separate file from the html and use something like DOMDocument to get the content from the div.
$dom = new DOMDocument();
$dom->loadHTMLFile('yourfile.html');
...

Answer 3

You cannot directly interact with the HTML DOM via PHP.
What you could do, is using a with an input containing your content. When submitting the form you can access the data via PHP.
But maybe you want to use Javascript for that task?
Nevertheless, a quick'n'dirty PHP example:
<form action="" method="post">
<textarea name="content">hello world</textarea>
</form>
<?php
if (isset($_POST['content'])) {
echo $_POST['content'];
}
?>
