Question

The $wrap array is a wrapped data and options array. How can I echo the array values of $options or $data calling the $wrap array variable?

$wrap = array($data, $options);

$data = array(1,2,3,4,5,6,7,8);
$options = array('a', 'b', "key" => "c", 'd', 'e');

Answer 1

$wrap = array($data, $options); is equivalent to $wrap = array(0=>$data, 1=>$options);.
I.e. via $wrap[1] you get the same array as $option thus $option[‘key’] => $wrap[1][‘key’]

E.g.

<?php
$data = array(1,2,3,4,5,6,7,8);
$options = array('a', 'b', "key" => "c", 'd', 'e');
$wrap = array($data, $options);
echo $wrap[1]['key'];

But you might want to use an associative index for $wrap to increase readability

<?php
$data = array(1,2,3,4,5,6,7,8);
$options = array('a', 'b', "key" => "c", 'd', 'e');
$wrap = array('data'=>$data, 'opts'=>$options);
echo $wrap['opts']['key'];
