Printing object properties with foreach

Question

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/>";
}
