Getting/Parsing XML data from an API that is done in PHP
I am installing a UPS shipping calculator API on my webstore, and it is getting prices correctly, which is great! I can't find any way to get those prices to a useful format though. I want to use them as a php variable.
For this example, we will call my cart cart.php.
The api is being executed by a file called ups.php.
When a customer puts items in their cart and fills in their zip code, they click a submit button, and they are directed to a new cart page that runs the ups.php script and displays the data on the page (which I will remove later so it can run in the background). If any of these files were .xml files I could probably learn how to parse xml data or use simpleXML commands in php... but they always seem to want a location of an xml file, which I don't have. Does anyone know how to get the XML data contained in one of my PHP files to be usable as a PHP variable?
Here is some of the code from ups.php:
<?php
$ch = curl_init("https://www.ups.com/ups.app/xml/Rate");
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch,CURLOPT_POST,1);
curl_setopt($ch,CURLOPT_TIMEOUT, 60);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch,CURLOPT_POSTFIELDS,$data);
$result=curl_exec ($ch);
echo ''. $result. '';
$data = strstr($result, '<?');
$xml_parser = xml_parser_create();
xml_parse_into_struct($xml_parser, $data, $vals, $index);
xml_parser_free($xml_parser);
$params = array();
$level = array();
foreach ($vals as $xml_elem) {
if ($xml_elem['type'] == 'open') {
if (array_key_exists('attributes',$xml_elem)) {
list($level[$xml_elem['level']],$extra) = array_values($xml_elem['attributes']);
} else {
$level[$xml_elem['level']] = $xml_elem['tag'];
}
}
if ($xml_elem['type'] == 'complete') {
$start_level = 1;
$php_stmt = '$params';
while($start_level < $xml_elem['level']) {
$php_stmt .= '[$level['.$start_level.']]';
$start_level++;
}
$php_stmt .= '[$xml_elem['tag']] = $xml_elem['value'];';
eval($php_stmt);
}
}
curl_close($ch);
return $params['RATINGSERVICESELECTIONRESPONSE']['RATEDSHIPMENT']['TOTALCHARGES']['MONETARYVALUE'];
}
?>
And here is what the text output looks like on my page when I run this .php file:
HTTP/1.1 100 Continue HTTP/1.1 200 OK Date: Wed, 25 Jul 2012 20:27:46 GMT

Well I got it figured out. here is the new code... Way shorter. way more simple.
I used php commands for explode(); and just normal array syntax, $newvariable = $existing_array [key#];
Thanks for the comments guys!
<?php
$ch = curl_init("https://www.ups.com/ups.app/xml/Rate");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch,CURLOPT_POST,1);
curl_setopt($ch,CURLOPT_TIMEOUT, 60);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch,CURLOPT_POSTFIELDS,$data);
$result=curl_exec ($ch);
$upsout = (explode('USD', $result, 15));
$handling = $upsout[3];
echo "Shipping cost is $";
echo $handling;
curl_close($ch);
}
?>
