Returning a String in PHP

[majik92]

I'm creating an updater for my app. What I did was get the file version and then encrypt it with a MD5 hash using Crypto.MD5DigestFromString(). Then I submitted the encrypted file version to my site using HTTP.Submit(). I used the POST method. The PHP file will return a string that tells the app that it is up-to-date or if it needs to update.

My question is how do I return a string to the app with PHP? Is this how you do it?

<?php

$app_file_version=$_POST["file_version"];
$latest_file_version=md5("1.0.7.6");

if ($app_file_version!==$latest_file_version) {
     echo("updatenow");
} else {
     echo("okay");
}

?>

The result of HTTP.Submit() will contain what ever the PHP script return.

result = HTTP.Submit(..your submit info..)

if result == "okay" then
    Dialog.Message("Info", "You have the latest version.")
elseif result == "updatenow" then
    Dialog.Message("Info", "There is a newer version avaialable.")
else
    -- handle anything else return or an error
end

Dermot hit the nail on the head. The HTTP.Submit action returns the raw text sent backby the Web page.

There is an example here to see another example. The mail PHP code returns success if all the variables are present. Otherwise it will return an error saying that one of the values was not present.
