将参数传递给函数的最佳方法？

Question

It's about code readability:

I've been dealing with this for a long time and I always wonder what would be the best approach to deal with passing parameters.

Lots of times, reading code from other programmers I find lines as such:

$Instance->functionCall('Abc123', 5, 1.24, 'XYZ', 642);

This makes me have to go to the Class file and take a look at what those parameters mean.

I do my best to write readable code by doing this:

$user_name = 'Abc123';
$age = 5;
$height = 1.24;
$hobbies = 'XYZ';
$num_brothers = 642;

$Instance->functionCall($user_name, $age, $height, $hobbies, $num_brothers);

Or this:

$Instance->functionCall($user_name = 'Abc123', $age = 5, $height = 1.24, $hobbies = 'XYZ', $num_brothers = 642);

But this variables occupies memory, not being used anywhere else. I like to think that this 'lost' memory space is worth it by being more readable, but I'd like to know if there is a better way.

Any ideas?

Thanks all!

Answer 1

What about something like this:

$Instance->functionCall([         // or $Instance->functionCall( array(
    'user_name'    => 'Abc123',
    'age'          => 5,
    'height'       => 1.24,
    'hobbies'      => 'XYZ',
    'num_brothers' => 642
]);

pass an array into the function. That way you have the readability of individual variables and can easily add more/less to the function as needed.
