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.
