After a longtime search i found a program that will create a query and returns the response from AWS..It works fine..
Program
<?php $key='Your aws key'; $pwd='Your AWS secret key'; // See docs ://docs.amazonwebservices.com/AWSEC2/latest/APIReference/------->Actions---->Describe Regions //for making a request to the aws $params = array( 'Action' => 'DescribeAvailabilityZones', 'AWSAccessKeyId' => $key, 'Timestamp' => gmdate('Y-m-d\TH:i:s\Z'), 'Version' => '2008-05-05', 'ZoneName.0' => 'us-east-1a', 'ZoneName.1' => 'us-east-1b', 'ZoneName.2' => 'us-east-1c', 'SignatureVersion' => 2, 'SignatureMethod' => 'HmacSHA256' ); uksort($params, 'strnatcmp'); $qstr = ''; foreach ($params as $key => $val) { $qstr .= "&{$key}=".rawurlencode($val); } $qstr = substr($qstr, 1); // Signature Version 2 $str = "GET " . "ec2.amazonaws.com " . "/ " . $qstr; $params['Signature'] = base64_encode( hash_hmac('sha256', $str, $pwd, true) ); // Generating a base64-encoded RFC //2104-compliant HMAC-SHA256 $req = 'https://ec2.amazonaws.com/?' . http_build_query( $params ); // encoded query string echo '<a href="'.$req.'">XML</a><p>';//For Navigating or creating a request. ?>
