I understand there are two problems, but when thinking in a programmable way to solve a problem I only think of solving what I can see.. mesh hanagem masalan trying to figure out any other problem that might have existed.

Nevertheless, this implementation could easily be hacked to make sure more than 2 arguments get through to your nameAndAge method. If one can’t see that straight away, one shouldn’t be attempting the first place.

It’s always a good idea to have the original problem in mind when working on a solution, it helps not getting carried away with your imagination.

If you were going to use nameAndAge() with empty arguments you didn’t need to use those new functions. I don’t really think this implementation solves the previously encountered problem(s), you still have to give the arguments in the order they are expected.

This would have worked just as good:

< ?php
	function nameAndAge($name, $age){
		if(!$name) $name = 'bingorabbit';
		if(!$age) $age = 15;
		echo 'Welcome ' . $name . ', you are ' . $age . ' years old.';
	}
	nameAndAge('',20); // prints Welcome bingorabbit, you are 20 years old.
	nameAndAge('ahmed',''); // prints Welcome ahmed, you are 15 years old.
?>

A much better usage of those functions would be as follows:

< ?php
	function nameAndAge(){
		$name = 'bingorabbit';
		$age = 15;
		$argsLength = func_num_args();
		$args = func_get_args();
		if( $argsLength == 1 ) {
			if( $args[0] ) {
				if( (int)$args[0] > 0 ) {
					$age = (int)$args[0];
				} else {
					$name = $args[0];
				}
			}
		} else if( $argsLength == 2 ) {
			if( $args[0] ) {
				if( (int)$args[0] > 0 ) {
					$age = (int)$args[0];
				} else {
					$name = $args[0];
				}
			}
			if( $args[1] ) {
				if( (int)$args[1] > 0 ) {
					$age = (int)$args[1];
				} else {
					$name = $args[1];
				}
			}
		}
		echo 'Welcome ' . $name . ', you are ' . $age . ' years old.';
	}
	nameAndAge(20); // prints Welcome bingorabbit, you are 20 years old.
	nameAndAge('ahmed'); // prints Welcome ahmed, you are 15 years old.
?>

I have two thoughts on mind right now. One, this totally rocks! PHP has become extremely flexible that I don’t even need to bother considering how many parameters I need to deal with.. and the second thought, this TOTALLY SUCKS! PHP has become extremely flexible just reading about it gives you the sense of flawlessness!

We all know what people do with JavaScript and how easily it could be hacked into. Who wants a more dangerous programming language that could potentially damage the users.

GAH!

Thanks though for sharing =) It’s the first new thing I’ve learnt in quite some time..
