#40886 [Bgs]: static methods assigned to instances

ID: 40886 User updated by: andrea at 3site dot it Reported By: andrea at 3site dot it Status: Bogus Bug Type: Class/Object related Operating System: Windows XP SP2 PHP Version: 5.2.1 New Comment: Finally a developer show me what PHP 5 developers did with static behaviour ... it's totally the same of Java language but you probably forget a tiny thing: PHP is not Java and Java supports methods overload too! At this point you implemented a keyword that get us less features than Java but its behaviour is the same of Java. I remember you that PHP isn't "pseudo" compiled, isn't fast as Java should be and, as I've just said, it doesn't support "pure" method overload so with Java You can change a method behaviour even if one overload is static but you can't do the same thing with PHP. This is an OO logic "problem" (if you don't want to call them *bug*) and to copy some Java concept inside a scripting language is not the way to have a better PHP, IMHO. Regards, Andrea Giammarchi Previous Comments: ------------------------------------------------------------------------ [2007-03-22 16:38:20] andrea at 3site dot it That's what I think about this feature. http://webreflection.blogspot.com/2007/03/php-5-developers-teach-us-what-does.html If a method is static, it should be static ... with PHP 5 a static method become an instance method (not static) ... what a feature! The solution is to remove static keyword from my static methods, well done! I hope PHP 6 will not have this ambiguity, regards. ------------------------------------------------------------------------ [2007-03-22 14:51:05] cellog@php.net this bug really shows how one person's bug is another person's feature. :) the syntax $a->method() allows you to call a static method of the class that $a is an instantiated object of, something I find useful for objects that contain static methods in a parent/child inheritance hierarchy. Using $a->method(), I don't need to do hackery to figure out which class "$a" is in order to call one of its static methods. Consider the alternative: <?php call_user_func_array(get_class($a), 'method', $args); ?> The above is the only alternative (save using reflection, which is even more verbose and inefficient) to: <?php $a->method($arg1, $arg1); ?> Which syntax do you prefer? The big difference between php 4 and php 5 is that a method declared as "static" does not have $this set. You'll get a fatal error, in fact, if you try to use $this in a static method. Why do you care so much about whether it's called with class::method() or $this->method()? You can't have two methods with the same name, one static and one non-static, so there is no possibility of accidentally calling the wrong one. If you are wanting absolutely "perfect" OO, there are plenty of other languages that will provide exactly the straightjacket and punishment you desire. If you want to code efficient, easy to maintain, working programs, use PHP. ------------------------------------------------------------------------ [2007-03-22 12:28:44] andrea at 3site dot it Derick, this is a bug (any Object Oriented logic). There's something wrong in your static keyword implementation, at least for methods that uses static keyword. This my last call and this is my last example: <?php class ExampleClass { public $StaticExample; public final function __construct(){ // bye bye public *parameter* $this->StaticExample = create_function('$never', 'return "welcome PHP5 ambiguity";'); } public final static function StaticExample(){ echo "StaticExample", "<br />"; } } $test = new ExampleClass(); ExampleClass::StaticExample(); exit($test->StaticExample()); ?> What does static keyword mean for PHP 5 developers? If this is an expected behaviour you should explain them in documentation page.
