How to set default argument of type array?

[eluser]jbibbings[/eluser]
I have this code in my controller:

Code:

function edit_address($data = array()){

// Do boring stuff

$data['result'] = 'My Result';
$this->load->view('includes/address', $data);


}

I am trying to set an empty array as my default for the argument in edit_address. This is because edit_address may or may not be receiving arguments depending on where it gets called.

PHP keeps spitting out errors in my view though when I assign a default value to an array:

Code:

Message: Undefined variable: result

Any idea why this could be? As soon as I remove the default assignment everything works fine.

Try moving the array declaration out of the function parameter list:
Instead, pass the value of $result as the default value. You may override the default (an empty string) when you call the function: edit_address('some other result');

Code:

function edit_address($result = ''){

// Do boring stuff

$data = array(); // declare the array
$data['result'] = $result; // this will contain either the default value or the value passed

$this->load->view('includes/address', $data);

}
