try this.......
foreach($data as $dat)
{
foreach($dat['ReferralDestinations'] as $key => $d)
{
echo $d['SiteName'];
echo $d['Url'];
echo $d['Title'];
}
}

It depends on how you are storing the data in the array. If you have an array that already has the last array data, it's very simple.
foreach ($myArray as $var) {
echo $var;
}
or access individual elements as $myArray['SiteName'], $myArray['Url'] etc..
Assuming you have the above data in an array of arrays called $arrayOfArrays
foreach ($arrayOfArrays as $myArray) {
// $myArray now holds first array, second array etc as the loop is executed
// First time it holds 'ApplicableProductOfferings', second time 'ReferralDesinations'..
// If the array is 'ReferralDesitnations' you can loop through that array
// to get the elements you are looking for SiteName etc as below
foreach ($myArray as $URLElement) {
echo $URLElement;
}
}

Answer 3

$array1 = [];
$array2 = [];
foreach ($array1 as $key=> $val) {
extract($array2, EXTR_IF_EXISTS, $val);
}
// extract() flags => EXTR_IF_EXISTS ...
