@function safe_args
|
|
@abstract Allows for array and direct function params as well as sanatization.
|
|
@author seek3r
|
|
@discussion This function is used to validate param data as well as offer flexible function usage.
|
|
@syntax safe_args($expected_args, $recieved_args,__LINE__,__FILE__);
|
|
@example
|
|
function somefunc()
|
|
{
|
|
$expected_args[0] = Array('name'=>'fname','default'=>'joe', 'type'=>'string');
|
|
$expected_args[1] = Array('name'=>'mname','default'=>'hick', 'type'=>'string');
|
|
$expected_args[2] = Array('name'=>'lname','default'=>'bob', 'type'=>'string');
|
|
$recieved_args = func_get_args();
|
|
$args = safe_args($expected_args, $recieved_args,__LINE__,__FILE__);
|
|
echo 'Full name: '.$args['fname'].' '.$args['fname'].' '.$args['lname'].'<br>';
|
|
//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.
