The format is in JSON , you need to decode it first by using json_decode()

Something like this...

$yourJSON = '{"name":"bedroom","rent":"sale","props":"","leases":""}';
$yourarray = json_decode($yourJSON,1);

You can then loop the $yourarray using the foreach construct like this.

foreach($yourarray as $key=>$val)
{
echo $key." ".$val."<br/>";
}

For retrieving a specific key from it..

   echo $yourarray['rent']; //"prints" sale
