Create array out of XML data - php

Question

I have a simple xml object like this as a result of Zend_Rest_Client_Result Object.
<userdetails>
<name value="jake"/>
<type value="user"/>
<attribute name="fname">
<value>Jake</value>
</attribute>
<attribute name="lname">
<value>Gordon</value>
</attribute>
<attribute name="phone">
<value>123-555-1234</value>
<value>999-888-7777</value>
</attribute>
</userdetails>
How can I create an array like this from the above XML object using PHP?
$userDetails = array();
$userDetails["name"] = "jake";
$userDetails["type"] = "user";
$userDetails["fname"] = "Jake";
$userDetails["lname"] = "Gordon";
$userDetails["phone"][0] = "123-555-1234";
$userDetails["phone"][1] = "123-555-1234";
Thanks,

Answer 1

$xml = '<userdetails><name value="jake"/><type value="user"/><attribute name="fname"><value>Jake</value></attribute><attribute name="lname"><value>Gordon</value></attribute><attribute name="phone"><value>123-555-1234</value><value>999-888-7777</value></attribute></userdetails>';
$simple = new SimpleXMLElement($xml);
$array = array();
if(isset($simple->name))
$array['name'] = (string) $simple->name->attributes()->value;
if(isset($simple->type))
$array['type'] = (string) $simple->type->attributes()->value;
if($foreach = $simple->xpath('//attribute[#name="fname"]/value'))
{
foreach($foreach as $node)
{
$array['fname'] = (string) $node;
}
}
if($foreach = $simple->xpath('//attribute[#name="lname"]/value'))
{
foreach($foreach as $node)
{
$array['lname'] = (string) $node;
}
}
if($foreach = $simple->xpath('//attribute[#name="phone"]/value'))
{
$array['phone'] = array();
foreach($simple->xpath('//attribute[#name="phone"]/value') as $node)
{
$array['phone'][] = (string) $node;
}
}
print_r($array);

function xmlstr_to_array($xmlstr) {
$doc = new DOMDocument();
$doc->loadXML($xmlstr);
return domnode_to_array($doc->documentElement);
}
function domnode_to_array($node) {
$output = array();
switch ($node->nodeType) {
case XML_CDATA_SECTION_NODE:
case XML_TEXT_NODE:
$output = trim($node->textContent);
break;
case XML_ELEMENT_NODE:
for ($i=0, $m=$node->childNodes->length; $i<$m; $i++) {
$child = $node->childNodes->item($i);
$v = domnode_to_array($child);
if(isset($child->tagName)) {
$t = $child->tagName;
if(!isset($output[$t])) {
$output[$t] = array();
}
$output[$t][] = $v;
}
elseif($v) {
$output = (string) $v;
}
}
if(is_array($output)) {
if($node->attributes->length) {
$a = array();
foreach($node->attributes as $attrName => $attrNode) {
$a[$attrName] = (string) $attrNode->value;
}
$output['#attributes'] = $a;
}
foreach ($output as $t => $v) {
if(is_array($v) && count($v)==1 && $t!='#attributes') {
$output[$t] = $v[0];
}
}
}
break;
}
return $output;
}
?>
Another quick and dirty method is:
<?php
$a = json_decode(json_encode((array) simplexml_load_string($s)),1);
?>
This is less robust and will create problem you code where to contain CDATA nodes as well.
