Access value of a multidimensional associative array Element inside the same array

$stats = array(
	"total" => array(
		"main" => array( 
		     "selector" => "template=50, parent=$formSuperSelector", 
		     "count" => $this->pages->find($stats['total']['main']['selector'])->count
		 ),
		 "yes" => array( 
		     "selector" => $stats['total']['main']['selector'].", teilnahme=yes", 
		     "count" => $this->pages->find($stats['total']['yes']['selector'])->count

	         "no" => array( 
		     "selector" => $stats['total']['main']['selector'].", teilnahme=no", 
		     "count" => $this->pages->find($stats['total']['no']['selector'])->count
		 )
	 ),

	 "intern" => array(
		  "main" => array( 
		       "selector" => "template=50, formtype=intern, parent=$formSuperSelector", 
		       "count" => $this->pages->find($stats['intern']['main']['selector'])->count
		   ),
		   "yes" => array( 
		       "selector" => $stats['intern']['main']['selector'].", teilnahme=yes", 
		       "count" => $this->pages->find($stats['intern']['yes']['selector'])->count
		   ),
		   "no" => array( 
		       "selector" => $stats['intern']['main']['selector'].", teilnahme=no", 
		       "count" => $this->pages->find($stats['intern']['no']['selector'])->count
		   )
	  ),

	  "extern" => array(
		   "main" => array( 
			"selector" => "template=50, formtype=extern, parent=$formSuperSelector", 
			"count" => $this->pages->find($stats['extern']['main']['selector'])->count
		    ),
		    "yes"  => array( 
			"selector" => $stats['extern']['main']['selector'].", teilnahme=yes", 
			"count" => $this->pages->find($stats['extern']['yes']['selector'])->count
		    ),
		    "no"   => array( 
			"selector" => $stats['extern']['main']['selector'].", teilnahme=no", 
			"count" => $this->pages->find($stats['extern']['no']['selector'])->count
		    )
	    ),

 );
			

 var_dump($stats['total']['main']['count']);

How can I bring this to work? I always get a "Notice: Undefined variable: stats in..." when trying to access:

 "count" => $this->pages->find($stats['intern']['yes']['selector'])->count

or

"selector" => $stats['intern']['main']['selector'].", teilnahme=yes",

I know I could do it like this(will probably do it like this ^^):

$totalselector = "template=50, parent=$formSuperSelector";
$internselector = "template=50, formtype=intern, parent=$formSuperSelector";
$externselector = "template=50, formtype=extern, parent=$formSuperSelector";

$stats = array(
...
...
"selector" => $totalselector, 
"count" => $this->pages->find($totalselector)->count
...
...
)

But now I am interested why the other method above doesnt works

EDIT: Just realised that this method is limited:

"yes"  => array( 
     "selector" => "$totalselector, teilnahme=yes", //need a new var with this selector 
     "count" => $this->pages->find($totalselector)->count //because of this
),

while this only works for "main" index:

"main"  => array( 
     "selector" => $totalselector, 
     "count" => $this->pages->find($totalselector)->count

All the $pages->find() calls are evaluated while creating $stats, which in turn means $stats is not defined at that moment. If you want the count to run "on-demand" you'd need to look into using anonymous functions. 

Also using $pages->find()->count is most of the time an anti-pattern. If you're not using those pages, but only the count rather user $pages->count($selector). The latter does only count the pages in the db, whereas your version does load all those pages and does count them in memory (php). 

Edit:

Just to make things more clear about the array creation. You're building up an array and after the whole array is computed – with all dynamic calls being evaluated to static values – you're saving the data into the variable $stats. You could go another way like this:

$stats = array(); // Create array; $stats !== undefined
$stats["total"] = array(
  ["main"] => array(),
  ["yes"] => array()
);

// Update each value one at a time
$stats["total"]["main"]["selector"] = "template=50, parent=$formSuperSelector";
$stats["total"]["main"]["count"] = $this->pages->count($stats['total']['main']['selector']);

at the moment i have total pages of 317. But when I do $this->pages->count($selector), i get somehow 415?

Can you post the selector for that? Also in which context do you have that issue (module, template or bootstraped)? Irrespective of that issue, you wouldn't want to load 300 pages (fully with all their field values) just to count how many you have.

Nevermind, it works now with your method.

The $pages->count() does work? If not than it would be nice to investigate this further, because it should return the same as counting locally.

$stats = array();
$mainIndexes = array("total", "intern", "extern");

foreach ($mainIndexes as $mainIndex) {
	$stats[$mainIndex] = array(
		'main' => array(),
		'yes' => array(),
		'no' => array(),
	);
}

$stats['total']['main']['selector'] = "template=50, parent=$formSuperSelector";
$stats['total']['main']['count'] = $this->pages->count($stats['total']['main']['selector']);

$stats['total']['yes']['selector'] = $stats['total']['main']['selector'].", teilnahme=yes";
$stats['total']['yes']['count'] = $this->pages->count($stats['total']['yes']['selector']);

$stats['total']['no']['selector'] = $stats['total']['main']['selector'].", teilnahme=no";
$stats['total']['no']['count'] = $this->pages->count($stats['total']['no']['selector']);

$stats['intern']['main']['selector'] = "template=50, formtype=intern, parent=$formSuperSelector";
$stats['intern']['main']['count'] = $this->pages->count($stats['intern']['main']['selector']);

$stats['intern']['yes']['selector'] = $stats['intern']['main']['selector'].", teilnahme=yes";
$stats['intern']['yes']['count'] = $this->pages->count($stats['intern']['yes']['selector']);

$stats['intern']['no']['selector'] = $stats['intern']['main']['selector'].", teilnahme=no";
$stats['intern']['no']['count'] = $this->pages->count($stats['intern']['no']['selector']);
		
$stats['extern']['main']['selector'] = "template=50, formtype=extern, parent=$formSuperSelector";
$stats['extern']['main']['count'] = $this->pages->count($stats['extern']['main']['selector']);

$stats['extern']['yes']['selector'] = $stats['extern']['main']['selector'].", teilnahme=yes";
$stats['extern']['yes']['count'] = $this->pages->count($stats['extern']['yes']['selector']);

$stats['extern']['no']['selector'] = $stats['extern']['main']['selector'].", teilnahme=no";
$stats['extern']['no']['count'] = $this->pages->count($stats['extern']['no']['selector']);

print_r($stats);

It works like a charm.
