如何在PHP(DOM选择器)中按类名获取元素?

Apparently, in PHP, there are a few DOM selectors like getElementById and getElementsByTagName but not the class selector, getElementsByClassName that is in javaScript, but strangely, not in PHP. Now, I have made a project that has to use class selectors in order to locate the elements in that particular page's DOM, but nethertheless, considering there's no getElementsByClassName method in PHP; I can't complete my project correctly.

So, how is it possible to apply "get elements by class name" in the PHP Document Object Model(DOM)?

Any help would be appreciated!
