Can I loop through a SimpleXML object in PHP?

Hi I have an xml file like that

<param typ="bool" nazwa="balkon">true</param>

<param typ="bool" nazwa="lazienka_wc">true</param>

<param typ="int" nazwa="liczbapieter">5</param>

<param typ="int" nazwa="liczbapokoi">3</param>

<param typ="int" nazwa="liczbalazienek">1</param>

I am looping through this like that:

            foreach($oferta->param as $p){
                print_r($p->attributes()->nazwa);
            }

I print out nazwa attr for every param but how can i get values: true, true, 5, 3, 1?

    Try this:

    $xml = <<<XML
   <root>
       <param typ="bool" nazwa="balkon">true</param>
       <param typ="bool" nazwa="lazienka_wc">true</param>
       <param typ="int" nazwa="liczbapieter">5</param>
       <param typ="int" nazwa="liczbapokoi">3</param>
       <param typ="int" nazwa="liczbalazienek">1</param>
    </root>
XML;
$oferta = new SimpleXMLElement($xml);
$values = [];
foreach($oferta->param as $p){
    $values[] = $p;
}
error_log('values: '.implode(', ',$values));

    Which outputs in my error log file:

    values: true, true, 5, 3, 1

    To get the string content of a SimpleXMLElement, you cast it to a string:

    $example = simplexml_load_string('<foo>Hello</foo>');
$content = (string)$example;
var_dump($content); // string(5) "Hello"

    So in your case, you want to cast $p to string in the loop:

    foreach($oferta->param as $p){
    $value = (string)$p;
}

    Also, there is a short-hand for $p->attributes()->nazwa, which is $p['nazwa']. With either syntax, that also returns an object, so you probably want to cast that to a string as well:

    foreach($oferta->param as $p){
    $value = (string)$p;
    $nazwa = (string)$p['nazwa'];
}
