variable echoing out the last of 3 numbers - php

Question

Hi so I've currently got a output echoing 176 8 58 from a web scraping script. I want to pack this script up into a variable and echo it out in other places on the website.
I've packed this up by doing this
ob_start();
echo $node->nodeValue. "\n";
$thenumbers = ob_get_contents();
ob_end_clean();
but when I echo it out like this
Now on the website the numbers are in spans and are split up by "/" do I need to do anything fancy? I'm kind of new to PHP so let me know if its something stupid!
<?php echo $thenumbers ?>
my output is then 176 8 58
Would really appreciate a bit of help
(web scraping script i'm using had to hide the website i'm scraping as its in development)
<?php
$teamlink = rwmb_meta( 'WEBSITE_HIDDEN' );
$arr = array( $teamlink );
foreach ($arr as &$value) {
$file = $DOCUMENT_ROOT. $value;
$doc = new DOMDocument();
$doc->loadHTMLFile($file);
$xpath = new DOMXpath($doc);
$elements = $xpath->query("//*[contains(#class, 'table')]/tr[3]/td[3]/span");
if (!is_null($elements)) {
foreach ($elements as $element) {
$nodes = $element->childNodes;
foreach ($nodes as $node) {
ob_start();
echo $node->nodeValue. "\n";
$win_loss = ob_get_contents();
ob_end_clean();
}
}
}
}
?>
p.s I know the script works as its currently outputting standard text fine.

My apoligies if I have completely misunderstood your question.
If you want to add a "/" between the numbers, where the spaces are you could:
echo str_replace(' ','/',$thenumbers);
If you just want to show the last 3 digits (cleaning out the spaces from the string) you could;
echo substr(str_replace(' ','',$thenumbers),-3);
