How to remove html tag attributes in php

The code for removing html tag attributes in php is as follows:

$ Str = 'test'; $ str = stripslashes ($ str); echo htmlspecialchars ($ str )."
";

You want to enter test
In short: no matter $ str contains any attribute in the tag, only the tag itself is retained.
