note 85274 added to function.empty

@john_jian, et al PHP does have explicit type casting. Also consider that, due to the implicit casting that Anonymous pointed out, "-" == (int)"-" and "+" == (int)"-" both evaluate as bool(true). var_dump("-" == (int)"-"); var_dump("+" == (int)"-"); This is small hiccup that I ran into a few weeks back when validating some user input. I thought it was a bug at first, but it's not, it's just one of those gotchas that crop up sometimes when dealing with a typeless language. It would be preferable, however, if PHP could raise an E_NOTICE when it encounters a cast that results in a default value such as in the above case. ---- Server IP: 208.69.120.35 Probable Submitter: 66.215.165.244 ---- Manual Page -- http://www.php.net/manual/en/function.empty.php Edit -- https://master.php.net/note/edit/85274 Del: integrated -- https://master.php.net/note/delete/85274/integrated Del: useless -- https://master.php.net/note/delete/85274/useless Del: bad code -- https://master.php.net/note/delete/85274/bad+code Del: spam -- https://master.php.net/note/delete/85274/spam Del: non-english -- https://master.php.net/note/delete/85274/non-english Del: in docs -- https://master.php.net/note/delete/85274/in+docs Del: other reasons-- https://master.php.net/note/delete/85274 Reject -- https://master.php.net/note/reject/85274 Search -- https://master.php.net/manage/user-notes.php
