Retrieve Outer HTML of DOM Elements in PHP

You've encountered an issue while attempting to obtain the outer HTML of hyperlink elements within a DOM structure using the outerHTML property. The output only reflects the inner HTML, excluding the opening and closing tags.

Solution:

In PHP versions 5.3.6 and later, you can utilize the saveHtml method, which accepts a DOM node as an argument:

$domDocument->saveHtml($nodeToGetTheOuterHtmlFrom);

Alternative for Earlier PHP Versions:

For PHP versions prior to 5.3.6, saveXml can be used. While it generates XML-compliant markup, it may not create discrepancies for anchor elements:

$domDocument->saveXml($nodeToGetTheOuterHtmlFrom);
