//default result would be:
// Full name: joe hick bob<br>
}
Using this it is possible to use the function in any of the following ways
somefunc('jack','city','brown');
or
somefunc(array('fname'=>'jack','mname'=>'city','lname'=>'brown'));
or
somefunc(array('lname'=>'brown','fname'=>'jack','mname'=>'city'));
For the last one, when using named params in an array you dont have to follow any order
All three would result in - Full name: jack city brown<br>
When you use this method of handling params you can secure your functions as well offer
flexibility needed for both normal use and web services use.
If you have params that are required just set the default as ##REQUIRED##
Users of your functions can also use ##DEFAULT## to use your default value for a param
when using the standard format like this:
somefunc('jack','##DEFAULT##','brown');
This would result in - Full name: jack hick brown<br>
Its using the default value for the second param.
Of course if you have the second param as a required field it will fail to work.
