Get values from SimpleXMLElement Object for php array-CodePudding

I need help with this issue, it seems I can't get targetCurrency out of the SimpleXMLElement Object

XML

<channel>
    <title>XML ~~ Exchange Rates ~~</title>
    <language>en</language>
    <item>
        <baseCurrency>USD</baseCurrency>
        <targetCurrency>EUR</targetCurrency>
        <targetName>Euro</targetName>
        <exchangeRate>0.90900497</exchangeRate>
    </item>
</channel>


  $url = "http://www.floatrates.com/daily/usd.xml";
  $xml = simplexml_load_file($url);
    
foreach($xml->item as $rate){

$rate       = (string) $rate->exchangeRate;
$curr_code  = (string) $rate->targetCurrency;
 
$money[] = array('rate' => $rate, 'curr_code' =>  $curr_code);
 }
    
    print_r($money);

$money outputs:

Array
(
    [0] => Array
        (
            [rate] => 0.90947603
            [curr_code] => 
        )

    [1] => Array
        ( 
// ...and so on...

[curr_code] should output the ISO code, EUR, USD,AUD etc.

How can I fix it?

CodePudding user response：

Try it using xpath instead:

$items  = $xml->xpath("//item");
foreach($items as $item){
    $rate = $item->xpath('.//exchangeRate')[0];
    $curr_code  = $item->xpath('.//targetCurrency')[0]; 
    $money[] = array('rate' => $rate, 'curr_code' =>  $curr_code);
 }
    
print_r($money);

The output should be as exptected.
