Form Data Array in PHP functtion

I try to use the Form Data array in a PHP function.
The idea is to make a large form with Bootstrap radio buttons in modal windows
.
The code for the radio buttons in one window are in a custom code field.
I try to put some of the code in function, but the Form Data array is not accessible in that function.
Is there a way to solve this, other than put these 2 lines ( $val and $model) in every buttongroup.

<?php
$datamodel="klachten";                   // Model of the survey table
$name="lengte";                          // Name of the field in survey table
$model="lengte";                         // Model of the table used for the radio buttons
$label="Wat is uw lengte?";             // Label for the radio group
radio($datamodel, $name, $model, $label); 


Function radio($datamodel,$name, $model, $label)
{
$name= $datamodel."[".$name."]";        // Field in the Form Data Array (used in external function)
$val= $form->data[$datamodel][$model];  // Value of the field stored in survey table
$model= $form->data[$model] ;            // array with the fields for the radio buttons
echo \GCore\Helpers\bootradio::modelselect($name, $label, $model, $val); 
                                     // Function the create the radio buttons
}	
?>

Hi Rob,

It should work if you pass the $form->data array to the function

<?php
radio('klatchen', 'lengte', 'lengte', 'Wat is uw lengte?', $form->data ); 

function radio($datamodel,$name, $model, $label, $data)
{
  echo \GCore\Helpers\bootradio::modelselect( $datamodel."[{$name}]", $label, $data[$model], $data[$datamodel][$model]); 
   // Function the create the radio buttons
} 
?>

Hi Bob,

I thought about that to.
But my form is interactive, with a lot of fields that are displayed depending on the value of other fields.
Passing the complete $form-> array for every item is not very efficient.

For the moment I keep the extra lines.

Hi Rob,

In the current versions of PHP it's passed by reference anyhow so makes only a tiny difference.

Hi Bob,

Thanks , the references make it easier.
I skipped the radio function and just use the second function call now.
It will be a large interactive form with a lot of show/hide containers and tabs.
Reducing the code makes it easier to copy and paste the fields from my spreadsheet.
