I have to read an XML file from an URL
$map_url = \"http://maps.google.com/maps/api/directions/xml?origin=\".$merchant_address_url.\"&destination=\".$cus
you can get the data from the XML by using "simplexml_load_file" Function. Please refer this link
http://php.net/manual/en/function.simplexml-load-file.php
$url = "http://maps.google.com/maps/api/directions/xml?origin=Quentin+Road+Brooklyn%2C+New+York%2C+11234+United+States&destination=550+Madison+Avenue+New+York%2C+New+York%2C+10001+United+States&sensor=false";
$xml = simplexml_load_file($url);
print_r($xml);
