Access local variable from other function PHP

Question

I have a private function which has lots of variables, let's say these: $foo, $bar, $baz.

Inside the function, I call parent::_setViewVars(array('foo','bar','baz'));

This _setViewVars looks so:

protected function _setViewVars($a){
    foreach($a as $v){
        global $$v;
        $this->set($v, $$v);
    }
}

I just want to get rid off cakephp's shit like 80 lines of $this->set('selected_areas',$selected_areas);, that's what this function is for.

_setViewVars cannot access $$v, because it's not a global variable. Given that this function is being called from the context that has these variables, can I reach them somehow?

(by the way if there is a cakephp way of bulk setting view variables with the same names, tell me how -- I haven't found one)

PS: packing everything into an array is NOT a solution, we're talking about thousands of unneccessary square brackets here.

Take a look at compact, which creates array useful for your scenario. — rr-

I've tried it: compact also does not reach these variables. — Rápli András

Can you redefine parent::_setViewVars? Or skip calling it altogether in favor of your own loop in which you call ->set(), dealing with output of compact? — rr-

global? Seriously? Just use compact() in your controller actions (not in a redundant separate method): $this->set(compact('foo', 'bar', 'baz')); That's btw exactly what CakePHP does when baking controllers... — ndm

What you're looking for is actually pretty standard PHP:

compact() - Create array containing variables and their values

Example showing it's use in a CakePHP Action:

$var1 = "I";
$var2 = "love";
$var3 = "pizza!";
$this->set(compact('var1', 'var2', 'var3'));

(might want to try to tone down the hatred a bit - you're more likely to get help that way)
