I have an object array which has key values

Array ( [0] =>stdClass Object ( [privacy] => {"name": "on", "email": null, "mobile": null, "address": "on", "alt_contact": "on"} ) )

I need to print a string which will contain the comma separated keys which has values as 'on'. The resultant string should be 

$result = "name,address,alt_contact";

Please help

This would do the trick for you ..

$json = '{"name": "on", "email": null, "mobile": null, "address": "on", "alt_contact": "on"}';
$array = json_decode($json,true);

$str = "";
foreach($array as $key=>$value)
{
    if($value == "on")
        $str .= $key.",";
}
return rtrim($str,",");

result:- name,address,alt_contact

This is how your request translates to PHP:

I need to

This is the code, straight from the list above:

$json = '{"name": "on", "email": null, "mobile": null, "address": "on", "alt_contact": "on"}';
// Pass TRUE as second argument to get arrays back; stdObject is useless
$data = json_decode($json, TRUE);

// print comma separated keys of 'on'
echo(implode(',', array_keys($data, 'on')));

Thanks Jaimin, It helped

Had to get the $privacy object parsed in an array as

$userPrivacies = $userPrivacies[0]->privacy;

and used your code later.

so the solution becomes

$userPrivacies = $userPrivacies[0]->privacy;

$array = json_decode($userPrivacies,true);

$str = "";
foreach($array as $key=>$value)
{
   if($value == "on")
      $str .= $key.",";
}
echo rtrim($str,",");
