There's the "Magic Method" in PHP for __debuginfo()
<https://www.php.net/manual/en/language.oop5.magic.php#object.debuginfo>.

Also see PHP RFC: __debugInfo() <https://wiki.php.net/rfc/debug-info>.

You may have better luck asking the PHP devs how to best use this with GDB,
or the GDB folks how to use the extension.

Hope that helps!
