Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Due to the volume of reports we can not explain in detail here why your report is not a bug. The support channels will be able to provide an explanation for you. Thank you for your interest in PHP. >From the documentation on count. If var is not an array or an object with implemented Countable interface, 1 will be returned. There is one exception, if var is NULL, 0 will be returned. You probably want to look at empty() to see if it has any elements rather than use count().

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
