[PATCH] Allow null to string conversion for PHP 6

Playing around with PHP 6 I noticed that some functions start to complain about conversion of null values to strings: php -d error_reporting=65535 -r 'var_dump(urldecode(null));' Warning: urldecode() expects parameter 1 to be strictly a binary string, null given in Command line code on line 1 I think this is wrong and attached a patch against HEAD to fix this. Note: While the patch seems a bit hacky at first it is IMHO the simplest solution without having to resort to copy/paste or goto. But if you want another solution I'm happy with that too :-) - Chris
