#14285 [Com]: Forcing variable declaration

ID: 14285 Comment by: gvdefence-ncr at yahoo dot it Reported By: pnh102 at psu dot edu Status: Open Bug Type: Feature/Change Request Operating System: Redhat Linux 7.2 PHP Version: 4.0.6 New Comment: This feature is necessary in PHP. Try this simple example: error_reporting(E_ALL | E_NOTICE | E_STRICT); //E_STRICT for PHP5 class Test { var $mispelled_var; function Test($test) { $this->$mispeled_var = $test; /* ERROR: we think to instantiate $this->mispelled_var, but we forgot an 'l' and we are instantiating a new var. PHP does not raise any error or warning or notice. */ } }; All other languages would raise an error or at least a warning. I love PHP and I want it to grow, this is a neccesary feature. It is necessary to add a sort of gobal option that when activated makes PHP sensible to these type of errors.

It would be extremely convenient to have warnings on assignment as well - instead of just upon reading a non-existent variable - and instead of creating a variable when a value is first assigned to it, require a separate declaration using a "var" keyword or such. Obviously not as standard, but as an option... ------------------------------------------------------------------------ [2003-08-13 14:35:52] lsemel at yahoo dot com This is an important issue. E_ALL doesn't catch everything. It makes PHP harder to program compared to other languages where you can declare variables (Perl, Java, etc.) ------------------------------------------------------------------------ [2003-07-16 15:36:44] andrew_nefsky at hotmail dot com This is definitely an important issue. Not being able to declare variables creates a debugging nightmare! ------------------------------------------------------------------------ [2002-11-19 08:06:07] z95kahe at mtek dot chalmers dot se I realy think this is good idea. I've been looking for some tool to do this kind of checks and found none. For small scripts there is no need to have variable declaring but there are for longer multi file, multi developer projects. By making the checks an option we can have both modes available. ------------------------------------------------------------------------ [2001-11-29 11:39:07] hholzgra@php.net this would only catch read usage of undefined variables, but not assigning values to them see: <?php $typofree = "hallo"; ... $xtypofree = "ooops"; ?> nothing in PHP will warn you that you have a typo in the second assignment, so creating a new variable unintended ... moved to feature requests ... ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
