Accessing WP cron multidimensional array efficiently in PHP - php

Question

I need to access multiple arrays, the problem lies when I get to the arrays I need like below, I can't access it traditionally because the key will be different every time.
I'm dealing with the following array:
Array
(
[oe_schedule_charge] => Array
(
[617cdb2797153d6fbb03536d429a525b] => Array
(
[schedule] =>
[args] => Array
(
[0] => Array
(
[id] => cus_2OPctP95LW8smv
[amount] => 12
)
)
)
)
)
There are going to be hundreds of these arrays and I need a way to efficiently access the data within them. I'm using the following code with expected output:
function printValuesByKey($array, $key) {
if (!is_array($array)) return;
if (isset($array[$key]))
echo $key .': '. $array[$key] .'<br>';
else
foreach ($array as $v)
printValuesByKey($v, $key);
}
$cron = _get_cron_array();
foreach( $cron as $time => $hook ) {
if (array_key_exists('oe_schedule_charge', $hook)) {
echo '<div>';
echo date('D F d Y', $time);
echo printValuesByKey($hook, 'amount');
echo printValuesByKey($hook, 'id');
echo '</div>';
}
}
But I've never had to deal with this much data, so I would like to take the proper precautions. Any light that can be shed on accessing a multidimensional array like this in an efficient way would be greatly appreciated.

I would consider loading it into an object, then writing member functions to get what you want.
class myclass {
private $_uniqueKey;
private $_schedule;
private $_args = array();
private $_amount = array();
private $_id = array();
public function __construct($arrayThing)
{
foreach($arrayThing['oe_schedule_charge'] as $uniqueKey => $dataArray)
{
$this->_uniqueKey = $uniqueKey;
$this->_schedule = $dataArray['schedule'];
$this->_args = $dataArray['args'];
}
$this->_afterConstruct();
}
private function _afterConstruct()
{
foreach($this->_args as $argItem)
{
if(isset($argItem['amount']) && isset($argItem['id']))
{
$this->_amount[] = $argItem['amount'];
$this->_id[] = $argItem['id'];
}
}
}
public function getUniqueKey()
{
return $this->_uniqueKey;
}
public function getSchedule()
{
return $this->_schedule;
}
public function getArgs()
{
return $this->_args;
}
public function printShitOut($time)
{
//You define this. But if you do a print_r( on the object, it will tell you all the items you need. )
}
//code would be like this:
$cron = _get_cron_array();
foreach( $cron as $time => $hook )
{
$obj = new myclass($hook);
$obj->printShitOut($time);
}
