Answer 1

PHP code:
$hdr_array = http_parse_headers($header);
$str = $hdr_array['Location'];
//$str = 'https://domainName.com.au:8181/retailapi_test/Persons//15668?countryCode=AU';
echo getStringBetween($str , 'Persons//', '?countryCode');
function getStringBetween($str,$from,$to)
{
$sub = substr($str, strpos($str,$from)+strlen($from),strlen($str));
return substr($sub,0,strpos($sub,$to));
}

You can use parse_url function to explode URL.
Try
$hdr_array = http_parse_headers($header);
$string = $hdr_array['Location'];
//$string = "https://domainName.com.au:8181/retailapi_test/Persons//15668?countryCode=AU";
$personID = parse_url($string, PHP_URL_PATH);
$personID = str_ireplace('/retailapi_test/Persons//', '', $personID);
echo $personID;

Another take on the problem, using preg_split and preg_match etc
$headerlist="

$location=false;
$pieces=array_filter( preg_split( '#\n#', $headerlist ) );
foreach( $pieces as $pair ) {
list( $param, $value )=preg_split( '#:\s#',$pair );
if( strtolower( trim($param) )=='location' ){
$location=$value;
break;
}
}
$path=parse_url( $location, PHP_URL_PATH );
preg_match('#\d+#',$path,$matches);
$userid=$matches[0];
echo 'userid:'.$userid;
