#46322 [Opn]: count(FALSE) returns 1

ID: 46322 User updated by: dmitryshw at hotmail dot com Reported By: dmitryshw at hotmail dot com Status: Open Bug Type: Variables related Operating System: Montavista PHP Version: 5.2.6 New Comment: Should have mentioned that I saw that this is mentioned as an "example" but I don't see this being any less of a bug... unless you can please explain how count(FALSE) makes sense to return 1. Previous Comments: ------------------------------------------------------------------------ [2008-10-16 22:27:17] dmitryshw at hotmail dot com Description: ------------ As title states, count for FALSE return 1. I came across the problem when creating an array through unserialize and depending on count to tell me how many elements the array has to know if I should use it. This caused a bug when the string was empty, and unserialize faithfully returned FALSE. However the result was used by the subsequent code as an array because count returned 1. According to the docs, the parameter var must have a Countable interface... so FALSE has a Countable interface?? Reproduce code: --------------- $test = unserialize(NULL); print count($test); Expected result: ---------------- 0 Actual result: -------------- 1 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=46322&edit=1
