PHP 8.4

Hello; I do not see much activity on this list these days. Has it gone elsewhere mostly? Anyhow I am looking at the online manual, specifically the deprecations. I see a heading: Recursion during comparison ¶ <https://www.php.net/manual/en/migration84.incompatible.php#migration84.incompatible.core.recursion-comparison> Encountering recursion during comparison now results in an Error <https://www.php.net/manual/en/class.error.php> exception instead of a E_ERROR <https://www.php.net/manual/en/errorfunc.constants.php#constant.e-error> fatal error. I need some more information on the idea of Recursion during comparison: I have written a recursive function that walks the file system and can be programed to respond to files and directories. I its simplest form it just produces a file system mapping. But it can be used to delete, rename, and other operations. Does recursion during comparison apply to this? (examples possibly?) In truth I have a working function that does not normally produce E_ERROR. So I presume my question is partially answered. Thank you for time and attention JK
