PHP foreach循环破坏子对象

Question

I'm trying to access third party api which gives me object and sub object, for example:

stdClass Object
(
    [truncated] => 
    [text] => "some text"
    [user] => stdClass Object
        (
            [count] => 9370
            [comments_enabled] => yes

When I try and loop through the object with the following code I get an error at the start of sub-object 'user'. Can anyone help me either 1) iterate through the sub-object, or 2) block the sub-object from the loop.

The code:

$test = $s[0];
$obj = new ArrayObject($test);
foreach ($obj as $data => $name) {
print $data . ' - ' . $name . '<br />';
}

thanks

It's because the 'user' field is an object, so you need to separately run through each field within that object

function iterateObject($obj, $name='') {

  //for each element        
  foreach ($obj as $key=>$val) {
    $myName = ($name !='') ? "$name.$key" : $key;

    //if type of the element is an object or array 
    if ( is_object($val) || is_array($val) ) {
      //if so, iterate through its properties
      iterateObject($val, $myName);
    }
    //otherwise output name/ value combination
    else {
      print "$myName - $val <br/>";
    }

  }

}

$test = $s[0];
$obj = new ArrayObject( $test );
iterateObject( $obj );

Will output

truncated - 
text - some text
user.count - 9370
user.comments_enabled - yes
