I’ve been trying to get this to work and while I have tried many methods posted on this site on other pages, I can’t get any of them to work.
I need to identify the last key so that my results don’t have a , at the end. This sounds like such and easy task but I just cant seem to get it to work! At this point I’m guessing I’ve just had a typo or something that I overlooked. Any help would be greatly appreciated.
This is what I have:
<?php $searchString = $_GET["s"]; $prefix = 'http://link_to_my_xml_file.xml?q='; $suffix = '&resultsPerPage=100'; $file = $prefix . $searchString . $suffix; if(!$xml = simplexml_load_file($file)) exit('False'.$file); foreach($xml->results->result as $item) { echo $item->sku . ","; } ?>
Now this works just fine, it just has a , at the end:
12345,23456,34567,45678,
For reference my xml file is laid out like: results->result->sku, but with a lot more mixed in. I’m just singling out the fields.

Consider identifying the first instead?
$first = true; foreach($xml->results->result as $item) { if ($first) { $first = false; } else { echo ','; } echo $item->sku; }
