Closed 7 years ago.
So I am trying to get a XML response after calling a URL with params (GET request). I found this code below, which is working.
$url = "http://...";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true );
curl_setopt($ch, CURLOPT_ENCODING, "gzip,deflate");
$response = curl_exec($ch);
curl_close($ch);
echo $response;
But as response I am getting a huge string with no commas (so I cannot explode it). And this string has only values, no keys.
Is there a way to get an associative array instead?
The XML is like:
<?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?>
<transaction>
<date>2011-02-10T16:13:41.000-03:00</date>
<code>9E884542-81B3-4419-9A75-BCC6FB495EF1</code>
<reference>REF1234</reference>
<type>1</type>
<status>3</status>
<paymentMethod>
<type>1</type>
<code>101</code>
</paymentMethod>
<grossAmount>49900.00</grossAmount>
<discountAmount>0.00<discountAmount>
(...)
SO I would like to have an array like:
date => ...
code => ...
reference => ...
(and so on)
Is that possible? If so, how?
EDIT: I don´t agree with the "this questions is already answered" tag. No code found on the indicated topic solved my issue. But, anyhow, I found a way, with the code below.
$url = http://...;
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$transaction= curl_exec($curl);
curl_close($curl);
$transaction = simplexml_load_string($transaction);
var_dump($transaction); //retrieve a object(SimpleXMLElement)

Answer 1

I have had good luck using code like this:
$url = "http://feeds.bbci.co.uk/news/rss.xml";
$xml = file_get_contents($url);
if ($rss = new SimpleXmlElement($xml)) {
echo $rss->channel->title;
}

I use something like this (very universal solution):
http://www.akchauhan.com/convert-xml-to-array-using-dom-extension-in-php5/
Only thing is I exclude the attributes part as I don't need them for my cases
<?php
class xml2array {
function xml2array($xml) {
if (is_string($xml)) {
$this->dom = new DOMDocument;
$this->dom->loadXml($xml);
}
return FALSE;
}
function _process($node) {
$occurance = array();
foreach ($node->childNodes as $child) {
$occurance[$child->nodeName]++;
}
if ($node->nodeType == XML_TEXT_NODE) {
$result = html_entity_decode(htmlentities($node->nodeValue, ENT_COMPAT, 'UTF-8'),
ENT_COMPAT,'ISO-8859-15');
} else {
if($node->hasChildNodes()){
$children = $node->childNodes;
for ($i=0; $i < $children->length; $i++) {
$child = $children->item($i);
if ($child->nodeName != '#text') {
if($occurance[$child->nodeName] > 1) {
$result[$child->nodeName][] = $this->_process($child);
} else {
$result[$child->nodeName] = $this->_process($child);
}
} else if ($child->nodeName == '#text') {
$text = $this->_process($child);
if (trim($text) != '') {
$result[$child->nodeName] = $this->_process($child);
}
}
}
}
}
return $result;
}
function getResult() {
return $this->_process($this->dom);
}
}
?>
And call it from your script like this:
$obj = new xml2array($response);
$array = $obj->getResult();
The code is very self explanatory, Objective approach and it can easily be modified to exclude or include parts at desire.
simply load XML into DOM Object, then recursively check for children and fetch respective values.
Hope it helps
