Update Check with PHP - php

Question

I'm working on an update system that checks a remote file string
$local = simplexml_load_file(root_p.'/version.xml');
$remote = simplexml_load_file("mygithuburltoblob/version.xml");
if($local->build == $remote->build) {
} else {
echo "Version ".$remote->version." Available now";
}
But even if the build numbers match it still returns that the update is available. Does anyone know why that would be?
(Yes root_p is already defined, the problem isn't loading and retrieving the values)
Remote Var Dump
object(SimpleXMLElement)#12 (6) { ["title"]=> string(11) "Loopy Cubix" ["author"]=> string(12) "Morgan Green" ["version"]=> string(3) "1.0" ["build"]=> string(4) "1111" ["type"]=> string(5) "Alpha" ["feed"]=> object(SimpleXMLElement)#15 (0) { } }
Local Var Dump
object(SimpleXMLElement)#11 (6) { ["title"]=> string(24) "Looped Cubix Pre Release" ["author"]=> string(12) "Morgan Green" ["version"]=> string(3) "1.0" ["build"]=> string(4) "1111" ["type"]=> string(6) "Closed" ["feed"]=> object(SimpleXMLElement)#15 (0) { } }
On the top of the page is my output from
<?php
$local = simplexml_load_file(root_p.'/version.xml');
$remote = simplexml_load_file("https://raw.githubusercontent.com/Doxramos/Invontrol/master/version.xml");
echo "Local: ". gettype($local->build);
foreach($local->build as $build) {
echo $build. "<br />";
}
echo "Remote: ". gettype($remote->build);
foreach($remote->build as $build) {
echo $build. "<br />";
}
Shows both as an object with the same value.

As I see that oject is no equal, example of some compared elements:
["title"]=> string(11) "Loopy Cubix"
["title"]=> string(24) "Looped Cubix Pre Release"

The issue had to do with whitespace while parsing the XML data. I ended up fixing it by replacing
if($remote->build == $local->build) {
}
else {
//Output Update Information
}
with
$trimmed_local = trim($local->build);
$trimmed_remote = trim($remote->build);
And using the new variables as my comparison operators
if($trimmed_local == $trimmed_remote) {
}
else {
//Output Update Information
}
