I want to get street view pano_id using latitude and longitude. I met to get that from this link. http://cbk0.google.com/cbk?output=xml&ll=40.714103,-74.006206

It returns xml output and I want to get that pano_id from it. If can get A,B and C all pano_ids really appreciate that.

You want to use PHP's SimpleXML.

<?php

$xml = new SimpleXMLElement(file_get_contents('http://cbk0.google.com/cbk?output=xml&ll=40.714103,-74.006206'));

foreach ($xml->data_properties as $element) {
    echo $element->attributes()->pano_id . "<br/>";
}

foreach ($xml->annotation_properties->link as $element) {
    echo $element->attributes()->pano_id . "<br/>";
}
