How to loop through SimpleXML Element Key Attributes using PHP

Question

Can't figure out how to loop through SimpleXMLElement Attributes. Try different methods, still without success..

here is xml:

<items>
<main>
<user_id>3370</user_id>
<msg_count>19</msg_count>
</main>
<msg category="/real-estate/residences/riga/" internal_id="51092" sid="Pārdod">

here is my php:

<?php
$curl = curl_init();

curl_setopt_array($curl, [
CURLOPT_URL => "https://www.------.com/xml/ss?id=178&user_id=3370",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
CURLOPT_HTTPHEADER => [
"Content-Type: text/xml"
],
]);

$response = curl_exec($curl);
$xml = simplexml_load_string($response, "SimpleXMLElement", LIBXML_NOCDATA);
$err = curl_error($curl);
curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {

foreach($xml->msg as $row){

  echo $row->phones. "<br />";
  echo $row->email. "<br />";
  echo $row->text. "<br />";

  foreach ($row->attributes() as $key => $value) {

    echo $key ." : ". $value ."<br />";
  }

  foreach($row->images->imgs as $key => $value){

      echo "<img src=".$value." alt='' width='150px' height='auto'> ";
      //echo $key . $value;
  }
  echo "<br />";
  
  foreach ($row->options->opt->attributes() as $value) {
    
      echo  $value ." : ";

      foreach($row->options->opt as $key => $value){

        echo  $value. "<br />";

    }
  }
}

}
?>

Here is the part where Im stuck:

Need some help, .. This is the part I need to loop through () and get something like this (attributes name: value / title1 : € : 299000.00 ) -->

Maybe is some better way to success, ... ::)) Thanks!

If that is really the XML you're using as input, there is an excess closing MSG tag. That might cause some troubles with parsing.

<items>
  <main>
    <user_id>3370</user_id>
    <msg_count>19</msg_count>
  </main>
</msg> <!-- THIS ONE -->

And regarding the options, if I understood correctly, you might want to loop through the options just once and inside that to loop through the attributes of the option you're currently in.

  foreach ($row->options->opt as $opt) {
    
      foreach($opt->attributes() as $key => $value){
        echo  $value. ": ";
      }

    echo  $opt->__toString() ."<br>";

  }
