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

$xmlString = <<<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>

XML;



$xml = simplexml_load_string($xmlString);

        

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);

This outputs:

Array

(

    [0] => Array

        (

            [rate] => 0.90947603

            [curr_code] => 

        )

)

[curr_code] should output 'EUR'.

How can I fix it?

My Answer:
You are trying to access the targetCurrency element from the $rate variable, which is already set to the exchangeRate element. Instead, you should access the targetCurrency element directly from the $xml object. Here is the corrected code:

php
$xmlString = <<

en

USD
EUR
Euro
0.90900497


XML;

$xml = simplexml_load_string($xmlString);

$money = array();

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);


This should now output:


Array
(
[0] => Array
(
[rate] => 0.90900497
[curr_code] => EUR
)
)


Now the curr_code should output 'EUR' as expected.
