RE: [PHP-DEV] Object comparison

I would like to place a suggestion for comparing objects (I hope it is no problem, because this does not have anything to do with Sara's question - but it came to my mind when I read her mail). It would be a great feature if objects could be compared to other objects with ">", "<" and the other operators, like it is suggested in RFC https://wiki.php.net/rfc/comparable The DateTime class offers this feature - it would be nice if this could be made usable for userland classes/objects, too.

For example: $a = new stdClass(); $b = new stdClass(); var_dump(null < $a); var_dump(false < $a); var_dump(true == $a); var_dump($a == $b); var_dump(0 < $a); var_dump(1 < $a); // false var_dump(2 < $a); // false var_dump("foo" < $a); var_dump("2" < $a); var_dump(tmpfile() < $a); Based on docs, I expect all nine of these to yield true, however in practice, the two marked "false" come out as false because the RHS object is converted to an integer (1), contrary to the docs. Doc bug? Or code bug? I'm inclined to call it a code bug, but wanted others' thoughts. -Sara -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
