In order to get the closing </html> tag using an HTML DOM parser with PHP, you can follow these steps:

  1. Use the file_get_html() function from a DOM parser library such as "simple_html_dom.php" to load the HTML content from a file or URL into a variable.
1
2
3
include 'simple_html_dom.php';

$html = file_get_html('your_html_file.html');


  1. Use the $html->find() method to find the closing tag or any other element you need. The method returns an array of elements that match the given selector.
1
2
3
4
$closingTags = $html->find('/html');

// You can also specify a more specific selector if needed:
// $closingTags = $html->find('html > /html');


  1. Access the first element of the array returned by the find() method, and retrieve the closing tag using the outertext property.
1
$closingTag = $closingTags[0]->outertext;


  1. You can then use the $closingTag variable as needed, for example, to add it to another HTML content or display it.
1
echo $closingTag;


Remember to adjust the library and the method calls according to the specific HTML DOM parser library you are using, as different libraries may have different syntax and methods.

If you are using the PHP built-in DOMDocument class, you can achieve this as follows:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
// Create a new DOMDocument object
$dom = new DOMDocument();

// Load the HTML content from a file or URL
$dom->loadHTMLFile('your_html_file.html');

// Find the closing </html> tag
$closingTags = $dom->getElementsByTagName('/html');

// Get the first closing tag
$closingTag = $closingTags->item(0)->C14N();

// Echo the closing </html> tag
echo $closingTag;


Note that the getElementsByTagName() method returns a DOMNodeList object, so you need to use the item() method to access the elements in the list. The C14N() method is used to get the well-formed closing tag as a string.


Remember to adjust the file name according to your HTML file's location, and you can modify the code as needed depending on your requirements.
