Variable $d comes from file_get_contents function to a URL.
$answer = @new SimpleXMLElement($d);
Below is output of the print_r($answer):
SimpleXMLElement Object
(
[Amount] => 2698
[Status] => OK
[State] => FL
[Country] => USA
)
How can I retrieve value of each element and add to an array? I can't figure it out.
In this simple case type casting will also work:
$my_array = (array)$answer
This should work:
$xml = simplexml_load_string($xmlstring);
$json = json_encode($xml);
$array = json_decode($json,TRUE);
json_encode and json_decode methods tend to choke when they come across a non-UTF-8 character. Wrapping in a try...catch would be wise, though I don't know if there would be a way to handle it properly (i.e. encode to UTF-8) without writing a custom parser.
json_encode and http_build_query seem to have issues interpreting <![CDATA[ ]]> tags. It seems both functions determine them to be empty objects, in which case http_build_query ignores it completely.The $answer can already work as an array. You can do this if you want put it in a real array,
$array = array();
foreach($answer as $k => $v) {
$array[$k] = $v;
}
I have a problem with this function because typecasting every XML child to an array can be problematic when the text is between CDATA tags.
I fixed this by checking if the result of the typecasting to an array is empty. If so typecast it to a string and you will get a proper result.
Here is my modified version with CDATA support:
function SimpleXML2ArrayWithCDATASupport($xml)
{
$array = (array)$xml;
if (count($array) === 0) {
return (string)$xml;
}
foreach ($array as $key => $value) {
if (!is_object($value) || strpos(get_class($value), 'SimpleXML') === false) {
continue;
}
$array[$key] = SimpleXML2ArrayWithCDATASupport($value);
}
return $array;
}
json_encode and http_build_query suffer from the exact same symptoms, so this approach is the most reliable.
$xml = simplexml_load_file('file.xml',SimpleXMLElement::class,LIBXML_NOCDATA); but then your function wasn't needed anymore, I could just do json_decode(json_encode((array) $xml),true);
this function parse a xml simpleXML recursive to array recursive
function SimpleXML2Array($xml){
$array = (array)$xml;
//recursive Parser
foreach ($array as $key => $value){
if(strpos(get_class($value),"SimpleXML")!==false){
$array[$key] = SimpleXML2Array($value);
}
}
return $array;
}
