Edit report at https://bugs.php.net/bug.php?id=62169&edit=1 ID: 62169 Comment by: valentiny510 at yahoo dot es Reported by: valentiny510 at yahoo dot es Summary: Use 'global' like a language structure Status: Wont fix Type: Feature/Change Request Package: *Programming Data Structures Operating System: Windows XP PHP Version: 5.4.3 Block user comment: N Private report: N New Comment: Joost if you can explain the 'evil' difference between this 2 examples and also tell me whitch is more 'hard to read' and why... I will give you the Nobel prize por programming... function test( ) { return global $variable; } function test( ) { global $variable; return $variable; } and... nobody asked you about your 'solution' with scope identifier global:: can be more evil yes.. but I do not care about your opinion, sorry Previous Comments: ------------------------------------------------------------------------ [2013-07-28 16:50:16] valentiny510 at yahoo dot es Nikic you are really a php developer ? Rasmus should choose better his team.. ------------------------------------------------------------------------ [2012-10-21 22:07:25] nikic@php.net As already noted in this thread, using globals is highly discouraged and as such it does not make sense to add any further functionality improving their use. Also (you say this yourself) you can use $GLOBALS. I don't understand why you don't want to use it. Language features aren't added simply because someone says "Hey, I want to access globals in one expression, but I don't want to use $GLOBALs, please add a feature that is fully equivalent but uses a different syntax". But even with the constraint of not using $GLOBALS you can easily build a function that would do something equivalent: function getGlobal($name) { global $$name; return $$name; } $foo = getGlobal('foo'); Marking this as Wontfix. ------------------------------------------------------------------------ [2012-10-21 21:06:48] joost dot koehoorn at gmail dot com My solution would be to introduce global as a scope identifier, so you could use it as: global::$object = new stdClass; global::$object->test = 'This is just a test'; function test() { return global::$object->test; } Although I do believe globals are evil and static class variables should be used at all times, this is a neat addition to avoid the very ugly and unclear global keyword. As it is now, you have to define a variable as global for it to resolve and act on the global variable. This makes code hard to read as it is not directly visible that this is the case. The above syntax would solve this problem. ------------------------------------------------------------------------ [2012-06-02 01:01:48] valentiny510 at yahoo dot es Imagine I have unset the, ( $GLOBALS ).. To access a 'global' object into the function, first must be called trowght global.. function test() { global $object; return $object->some_method( ); } I wonder if is posible to use (in the future :P) the 'global' like other language structures.. Ex: function test() { return( global $object->some_method( ) ); } I know ... you will ask me why not use the namespaces, reflections, references, traits, or whatever.. but .. its not the point ... ------------------------------------------------------------------------ [2012-06-02 00:59:13] valentiny510 at yahoo dot es In the first line I just wrote: "Imagine I have unset the ($GLOBALS)" for some reason.. (is ugly, security, memory consumption, the host provider doesn't allow) or who knows why ... I know how it works for now but the question is not about how to use "$GLOBALS". anyway, thanks for the time spent to answer ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
