Hallo!
I'm working on a project, where we distinguish between
"functions" and
"actions" in design, although in PHP both are implemented as
functions.
Is there a chance that PHP can use the word "action" as "function"?
E.g.:
public function doSomething() { .... }
public action doSomethingElse() { ... }
... is actually the same but would help to see the design also in
the code.
You could define a generic action function
function action($funcName, $funcArgs)
{
return $funcName($funcArgs);
}
and use it on any function you want to use as an action function
function printColor($color) {
echo 'color: '.$color.'<br>';
}
function printArea($width, $height) {
echo 'area: '.($width * $height).'<br>';
}
action('printColor', 'blue');
action('printArea', 3, 5);
You could then pass in any function that is visible to the action
function. You lose some efficiency but get your action function
Then again, you could also just prepend action functions with 'action_'
TIA, Ralph
