Printing object properties with foreach

I have an anonymous object with 10 properties and I need to print them in the following format: {name}->{value)

This is my code: 

$obj = new stdClass();

$obj->name = "Penka";
$obj->age = "25";
$obj->city = "Sofia";
$obj->street = "Hadji Dimitar street";
$obj->occupation = "PHP developer";
$obj->children = 1;
$obj->married = false;
$obj->divorced = true;
$obj->salary = 1300;
$obj->car = "Nissan Micra";

foreach($obj as $data)
{
    echo key($obj).' -> '.$data.'<br/>';
}

I don't know how to output the key but I found this function key() and it somewhat working but the output is distorted. 

age -> Penka
city -> 25
street -> Sofia
occupation -> Hadji Dimitar street
children -> PHP developer
married -> 1
divorced -> 
salary -> 1
car -> 1300
-> Nissan Micra

The property name is missing and everything is 1 key behind. Why is this happening?

foreach has already advanced the pointer by the time you use the key() function, so it is ahead by one. Just expose the key in the foreach:

foreach($obj as $key => $data)
{
    echo "$key -> $data <br/>";
}
