array(
name => text,
surname => text,
country => text,
date => text
)
1) How can I save this array to file as xml file?
2) How to read this file then as array?

1Have you considered using JSON to serialize it instead? I am biased against XML. Too much fat =/NullUserException– NullUserException2010-09-20 22:24:34 +00:00Commented Sep 20, 2010 at 22:24

// save
$doc = new DOMDocument('1.0');
$doc->formatOutput = true;
$root = $doc->createElement('root');
$root = $doc->appendChild($root);
foreach($arr as $key=>$value)
{
$em = $doc->createElement($key);
$text = $doc->createTextNode($value);
$em->appendChild($text);
$root->appendChild($em);
}
$doc->save('file.xml');
// load
$arr = array();
$doc = new DOMDocument();
$doc->load('file.xml');
$root = $doc->getElementsByTagName('root')->items[0];
foreach($root->childNodes as $item)
{
$arr[$item->nodeName] = $item->nodeValue;

Using SimpleXML
for #1 (as in How to convert array to SimpleXML)
<?php
$xml = new SimpleXMLElement('<root/>');
array_walk_recursive($test_array, array ($xml, 'addChild'));
print $xml->asXML("file.xml");
for #2
$xml_data_as_object = simplexml_load_file("file.xml")
returns an object representation of the xml data.
convert the object to an array with:
$xml_data_as_array = array();
foreach ($xml_data->root as $children) {
$xml_data_as_array[] = array(
"name" => $children->name,
"surname" => $children->surname,
"country" => $children->country,
"date" => $children->date
);
}

Take a look at the Pear module XML::Serializer -- which also includes XML::Unserializer.
