Re: PHP 8.4

Hello,

Didn't know or forgot this. After verification and if I'm correct, recursion during comparison appears when PHP compares 2 objects. Infinite recursion can appear when one of the objects compared references himself.

Example :

class RecursiveObject {
    public $self;

    public function __construct() {
        $this->self = $this;
    }
}

$obj1 = new RecursiveObject();
$obj2 = new RecursiveObject();

try {
    $result = $obj1 == $obj2;
} catch (Error $e) {
    echo "Une erreur a été capturée : " . $e->getMessage();
}

Which results in PHP 8.3:

PHP Fatal error:  Nesting level too deep - recursive dependency? in /var/www/html/api-spotify/public/test.php on line 14
PHP Stack trace:
PHP   1. {main}() /var/www/html/api-spotify/public/test.php:0

And in PHP 8.4 :

Une erreur a été capturée : Nesting level too deep - recursive dependency?

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 ¶

Encountering recursion during comparison now results in an Error exception instead of a 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
