I have a form wih an "submit" button, when clicked it calls a display() function.
display() is a function that includes another .php file in where I have the funtcions to do different conversions to the ids.
My problem now is, I want to "echo" the converted ids to my html, which I can't since the variables of the conversions are inside function(s).
Currently I am doing the following, I have the function of the conversion (with the variables I want to echo to my HTML) in one part "php tags" and then I include "php tags, echo" in my HTML.
But sadly, I tried so many things, setting the variables to global, trying to define them elsewhere but the variables will stay undefined.
Basically I am asking, wheter I am doing something wrong, or if there are better/more logical ways of doing this, so I'll be able to call those variables. (remember I need them everytime, since a URL is being submitted when form is submitted.)
Here is my code (index.php)

The proper way to do this, is to return the object from your function and use it as needed. Please note that I am using PHP shorthand echo (<?=). An even better way to do this would be to have another function to format your variables with the expected strings so you don't need to do it in the HTML.
function urlCheck() {
$input = $_POST["profile_url"];
if(substr_count($input, ' ') === strlen($input)) {
echo "Enter URL";
return false;
} else {
return $input;
}
}
function display() {
$input = urlCheck();
if($input) {
require_once 'steamid.class.php';
$api_key = "XXXXXXXXXXXX";
$id = new SteamID($input,$api_key);
if ($id->resolveVanity()) {
return $id;
} else {
echo "Profile wasn't found!";
return false;
}
}
}
if(isset($_POST['submit']))
{
$id = display();
}
...
<h1><?= (isset($id)) ? "[U:1:".$id->toUserID()."], " : "" ?></h1>
...
<img onerror="this.style.display='none'" src="<?= (isset($id)) ? {$id->toAvatar()} : "" ?>">
