PHP实现数组array转换成xml的方法

<?php
$elementLevel = 0 ;
function array_Xml($array, $keys = '')
{
global $elementLevel;
if(!is_array($array))
{
if($keys == ''){
return $array;
}else{
return "\n<$keys>" . $array . "</$keys>\n";
}
}else{
foreach ($array as $key => $value)
{
$haveTag = true;
if (is_numeric($key))
{
$key = $keys;
$haveTag = false;
}
if($elementLevel == 0 )
{
$startElement = "<$key>";
$endElement = "</$key>";
}
$text .= $startElement;
if(!$haveTag)
{
$elementLevel++;
$text .= "<$key>" . array_Xml($value, $key). "</$key>\n";
}else{
$elementLevel++;
$text .= array_Xml($value, $key);
}
$text .= $endElement;
}
}
return $text;
}
$array = array(
"employees" => array(
"employee" => array(
array(
"name" => "name one",
"position" => "position one"
),
array(
"name" => "name two",
"position" => "position two"
),
array(
"name" => "name three",
"position" => "position three"
)
)
)
);
echo array_Xml($array);
?>
