You can read the variables if this was sent to your server as a Get request like...
$_Get['phoneNumber'], $_GET['hardwareSerialNumber'] and so forth
If you are just asking for help to decode the string...
$urlstring = 'phoneNumber=7018805137&deviceImeiId=lQAHMiAwBx%2B%2FchlgHKjWfA%3D%3D%0A&hardwareSerialNumber=bcZ%2Bb5VrI84UN%2FWXJj8hyQ%3D%3D%0A&macAddress=pDQheRx1nNFqOz%2Fw9Y9bI3I96uVKXjhkDXNhNgV%2FyGw%3D%0A&androidID=PQ9kdlHyznGdGKcl0QYh3hp4XeRUz0bBVMnABcxRsZ8%3D%0A&referralCode=7JMYUZ&lastEnabledTime=1481449847956&updateTime=1481449669855&installationTime=1481449669855';
foreach (explode('&', $urlstring) as $chunk) {
$param = explode("=", $chunk);
if ($param) {
printf("Value for parameter \"%s\" is \"%s\"<br/>\n", urldecode($param[0]), urldecode($param[1]));
}
}
It will print the following
Value for parameter "phoneNumber" is "7018805137"

Value for parameter "hardwareSerialNumber" is
