Try Array2XML (<a href="http://www.lalit.org/lab/convert-php-array-to-xml-with-attributes" rel="nofollow">http://www.lalit.org/lab/convert-php-array-to-xml-with-attributes</a>) this has worked for me.

<pre><code>$data = array(
 "Details" =&gt; array(
 "PID" =&gt; 1234,
 "OPID" =&gt; 1345
 ),
 "Parameters" =&gt; array(
 "HR" =&gt; 112,
 "SPO2" =&gt; 0
));


$xml = Array2XML::createXML('VitalParameters', $data)-&gt;saveXML();

echo $xml;
</code></pre>

Output 

<pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;VitalParameters&gt;
 &lt;Details&gt;
 &lt;PID&gt;1234&lt;/PID&gt;
 &lt;OPID&gt;1345&lt;/OPID&gt;
 &lt;/Details&gt;
 &lt;Parameters&gt;
 &lt;HR&gt;112&lt;/HR&gt;
 &lt;SPO2&gt;0&lt;/SPO2&gt;
 &lt;/Parameters&gt;
&lt;/VitalParameters&gt;
</code></pre>

This should get you on the right track, probably needs some tuning though (especially in regards to keys aswell as checking if $arr is an array/object in the first place... this was just to show you how to recursively iterate them and print the data).

Also, this snippet does not support XML attributes in any way.

<pre><code>&lt;?php
$data = array("VitalParameters"=&gt;array(
 "Details"=&gt;array(
 "PID"=&gt;1234,
 "OPID"=&gt;1345
 ),
 "Parameters"=&gt;array(
 "HR"=&gt;112,
 "SPO2"=&gt;0
 )));

function ArrayToXML($arr, $depth = 0, $maxDepth = 2)
{
 $retVal = "";
 foreach($arr as $key =&gt; $value)
 {
 $retVal .= "&lt;" . $key . "&gt;";

 $type = gettype($value);
 switch($type)
 {
 case "array":
 case "object":
 if ($depth &lt; $maxDepth)
 $retVal .= ArrayToXml($value, $depth+1, $maxDepth);
 else
 $retVal .= $type; // Depth &gt;= MaxDepth, not iterating here
 break;
 case "boolean":
 $retVal .= $value ? "true" : "false";
 break;
 case "resource":
 $retVal .= "Resource";
 case "NULL":
 $retVal .= "NULL";
 default:
 $retVal .= $value;
 }
 $retVal .= "&lt;/" . $key . "&gt;\n";
 }
 return $retVal;
}

echo ArrayToXML($data);
?&gt;
</code></pre>

Output:

<pre><code>&lt;VitalParameters&gt;&lt;Details&gt;&lt;PID&gt;1234&lt;/PID&gt;
&lt;OPID&gt;1345&lt;/OPID&gt;
&lt;/Details&gt;
&lt;Parameters&gt;&lt;HR&gt;112&lt;/HR&gt;
&lt;SPO2&gt;0&lt;/SPO2&gt;
&lt;/Parameters&gt;
&lt;/VitalParameters&gt;

I got solution like following code

<pre><code>&lt;?php
header("Content-type: text/xml; charset=utf-8");
$data = array(
 "Details" =&gt; array(
 "PID" =&gt; "1234","OPID" =&gt; "1345"
 ),"Parameters" =&gt; array(
 "HR" =&gt; "112","SPO2" =&gt; "0"
 )
);

$domtree = new DOMDocument('1.0', 'UTF-8');
/* create the root element of the xml tree */
$xmlRoot = $domtree-&gt;createElement("VitalParameters");
/* append it to the document created */
$xmlRoot = $domtree-&gt;appendChild($xmlRoot);

foreach ($data as $key=&gt;$value)
{
 $currentElement= $domtree-&gt;createElement($key);
 $currentElement= $xmlRoot-&gt;appendChild($currentElement);
 if(is_array($value))
 {
 foreach ($value as $k=&gt;$v)
 {
 $currentElement-&gt;appendChild($domtree-&gt;createElement($k,$v));
 }
 }
}

/* get the xml printed */
echo $domtree-&gt;saveXML();
</code></pre>

Output

<pre><code>&lt;VitalParameters&gt;
 &lt;Details&gt;
 &lt;PID&gt;1234&lt;/PID&gt;
 &lt;OPID&gt;1345&lt;/OPID&gt;
 &lt;/Details&gt;
 &lt;Parameters&gt;
 &lt;HR&gt;112&lt;/HR&gt;
 &lt;SPO2&gt;0&lt;/SPO2&gt;
 &lt;/Parameters&gt;
&lt;/VitalParameters&gt;
</code></pre>

blocks|key|4850859|text|我想-这肯定更简单：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4850860|function+arrayToXML($arr){

++$s+=+"";

++foreach($arr+as+$k+=>+$v){
++++if(is_array($v)){$v+=+arrayToXML($v);}
++++$s+.=+"<{$k}>{$v}</{$k}>";
++}

++return+$s;}|code-block|syntax|javascript|4850861|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

I think - this is must be more simple:

<pre><code>function arrayToXML($arr){

 $s = "";

 foreach($arr as $k =&gt; $v){
 if(is_array($v)){$v = arrayToXML($v);}
 $s .= "&lt;{$k}&gt;{$v}&lt;/{$k}&gt;";
 }

 return $s;}
</code></pre>

I have following array in PHP and I want to convert it equivalent XML.

<pre><code>$data = array("VitalParameters"=&gt;array(
 "Details"=&gt;array(
 "PID"=&gt;1234,
 "OPID"=&gt;1345
 ),
 "Parameters"=&gt;array(
 "HR"=&gt;112,
 "SPO2"=&gt;0
 )));
</code></pre>

Following XML tree structure which I expected

<pre><code>&lt;VitalParameters&gt;
 &lt;Details&gt;
 &lt;PID&gt;1234&lt;/PID&gt;
 &lt;OPID&gt;1345&lt;/OPID&gt;
 &lt;/Details&gt;
 &lt;Parameters&gt;
 &lt;HR&gt;112&lt;/HR&gt;
 &lt;SPO2&gt;0&lt;/SPO2&gt;
 &lt;/Parameters&gt;
&lt;/VitalParameters&gt;
</code></pre>

I tried many things but no luck. If any more information required just comment I will give additional information.
