note 84303 added to language.types.string

That's my point, nullhility. Using the null character, the behaviour is clear: a null character is a string and $a[1] will be a string. Period. Now see it my way: I set $a[1] (string) to a different type (NULL) and PHP has to "invent" a corresponding value related to string type. He uses a null char. But the page "converting to string" of this manual (this_page#language.types.string.casting) clearly says "NULL is always converted to an empty string.". This is the strange behaviour I wanted to underline. ---- Server IP: 213.92.11.19 Probable Submitter: 84.220.143.55 ---- Manual Page -- http://www.php.net/manual/en/language.types.string.php Edit -- https://master.php.net/note/edit/84303 Del: integrated -- https://master.php.net/note/delete/84303/integrated Del: useless -- https://master.php.net/note/delete/84303/useless Del: bad code -- https://master.php.net/note/delete/84303/bad+code Del: spam -- https://master.php.net/note/delete/84303/spam Del: non-english -- https://master.php.net/note/delete/84303/non-english Del: in docs -- https://master.php.net/note/delete/84303/in+docs Del: other reasons-- https://master.php.net/note/delete/84303 Reject -- https://master.php.net/note/reject/84303 Search -- https://master.php.net/manage/user-notes.php
