在PHP中将DOM元素转换为字符串

Question

I am running a Wordpress site and using WPML translation plugin. In WPML there is a method called icl_link_to_element(2880); that returns and generates the following element in the DOM:

<a href="https://www.someurl.com/es/atencion-al-cliente">Atención al cliente</a>

I want to convert this element to a string so that I can simply return and store the last part of the url atencion-al-cliente, into a unique variable.

What's the best way to get this done?

Answer to the comment below:

Two elements appear in the DOM now.

<a href="https://www.someurl.com/es/atencion-al-cliente">Atención al cliente</a>

and

"NULL
            "

Answer 1

First do the following steps to get that URL

1. $page = icl_object_id(2880, 'page', true);
2. $url = get_permalink($page);

Then use $parts = explode("/", $url) function and get the last element of that array, you can use array_pop()
