Building Array From Possible Variables

[quasiman]

Hi,

 

I'm building an array from two other arrays, and I want to loop through them for specific key/value pairs. The problem is that some of the pairs do not exist in every sub array, and so referencing them causes an unidentified offset error.

 

So....here's what I'm doing so far. How can I (easily and with minimum if/else statements) check whether they exist prior to generating my array?

 

<?php
$category = 'linux_hosting_plan';
$name = 'Starter';

print_r(returnHostPlan($category, $name));

function returnHostPlan($category, $name) {
$planDetails = getData('products/plan-details');
$customerPrice = getData('products/customer-price');
$plan = combineArray($planDetails['hosting'], $customerPrice['hosting']);
foreach ($plan as $key => $value) {
 if ($value[0]['category'] == $category && $value[0]['plan_name'] == $name) {		
	 $array = array(
		 'key' => $key,
		 'plan_name' => $value[0]['plan_name'],
		 'dbspace' => $value[0]['dbspace'],
		 'status' => $value[0]['status'],
		 'webspace' => $value[0]['webspace'],
		 'no_of_mail_accounts' => $value[0]['no_of_mail_accounts'],
		 'bandwidth' => $value[0]['bandwidth'],
		 'hosting_location' => $value[0]['hosting_location'],
		 'noofdbs' => $value[0]['noofdbs'],
		 '12' => $value[1]['add'][12],
		 '36' => $value[1]['add'][36],
		 '48' => $value[1]['add'][48]
	 );
 }
}
return $array;
}
?>

 

This creates:

Notice: Undefined offset: 48 in /../../planDetails.php on line 35
