Question

I am looking for a way to output a multidimensional array as a simple table.

I got it by processing xml available here http://google.com/complete/search?output=toolbar&q=adam with the simple function

function convertXmlObjToArr($obj) { 
$json = json_encode($obj);
$array = json_decode($json,TRUE);

return $array;

}

and got an array

   array(1){ ["CompleteSuggestion"]=>
  array(10) {
    [0]=>
    array(1) {
      ["suggestion"]=>
      array(1) {
        ["@attributes"]=>
        array(1) {
          ["data"]=>
          string(12) "adam sandler"
        }
      }
    }
    [1]=>
    array(2) {
      ["suggestion"]=>
      array(1) {
        ["@attributes"]=>

          string(9) "137000000"
        }
      }
    }
  }
}

Now I would like to output it and face 2 problems:

1. How do I “dig into” the relevant information (“data” and “int”) in an array structured like this? So far I was dealing with much simpler arrays (not so “deep”).
   I am trying to for it via foreach loop

foreach($googleKeywords->CompleteSuggestion as $suggestion){


            echo"{$this->suggestion->data}";
         }

but keep getting “Trying to get property of non-object” error.

1. As you notice some of the data is not complete – there is a name in “data” but not corresponding “int”… would be there a way to echo “no data” whether “int” is not set?

All the best,

Adam

Thanks,

The final code that worked involved nested loops and is as follows:

<pre>foreach($keywords as $suggestion){
 foreach ($suggestion as $finalSuggestion){
   echo "<p>".$finalSuggestion['suggestion']['@attributes']['data']."</p>";
   echo $finalSuggestion['num_queries']['@attributes']['data']."<br/>";
    if (array_key_exists('num_queries', $finalSuggestion)) {
    echo "<p> ".$finalSuggestion['num_queries']['@attributes']['int']." </p>";
    }
    else
        {
        echo "<p>no data</p> ";
    }
     }

}
</pre>  

PS. Sorry for the awful formatting of the code , still not sure how to do it properly here…. I usually just put < pre> but it goes wild now….
