PHP object to array then return key

[razorsese]

I need to return a specific key from the object converted to array but it seems that it dosent work

 

$toarray = (array)$tmp;
$name = array_keys($toarray,'name');
print_r($toarray);

print:Array ( [id] => 9 [name] => dfd [text] => fdsf [rating] => 0 [totalv] => 0 )

 

and when i try to return the key

 

print_r($name);

 

Array ( [0] => rating [1] => totalv )

 

But I only need the key whit the 'name' value
