note 77445 added to functions.returning-values

It took my some 30 minutes to figure out this strange thing that I happened to have, wasn't aware of this before. Posting here so that it might help for some of you as well.. Let say you have a function that returns a 0 or 1: function isValid(){ if(true) return 1; else return 0; } In your code you should call this as: if (someFunction == '0') { //mind quotes! // do something } it is very strange, but it didn't work for me when I tried ==0, and even when I tried if (!someFunction) .... I even tried to have my function return booleans as in 'return false' and return 'true'. I have PHP 4.4.6, 1.3.37 (Unix) PS: don't know whether it is a bug, or normal behavior :/ Peace. @mm ---- Server IP: 69.147.83.197 Probable Submitter: 76.16.212.113 ---- Manual Page -- http://www.php.net/manual/en/functions.returning-values.php Edit -- https://master.php.net/note/edit/77445 Del: integrated -- https://master.php.net/note/delete/77445/integrated Del: useless -- https://master.php.net/note/delete/77445/useless Del: bad code -- https://master.php.net/note/delete/77445/bad+code Del: spam -- https://master.php.net/note/delete/77445/spam Del: non-english -- https://master.php.net/note/delete/77445/non-english Del: in docs -- https://master.php.net/note/delete/77445/in+docs Del: other reasons-- https://master.php.net/note/delete/77445 Reject -- https://master.php.net/note/reject/77445 Search -- https://master.php.net/manage/user-notes.php
