PHP - 从对象获取所有值而不知道属性

I'm having an issue with displaying object properties.

normally you would call them using :

$obj["name"]

but what if you did not know the properties e.g "name"

for an array , you can simply call $arr[0] , $arr[1] etc...

But if i have this object (print_r):

stdClass Object ( [id] => 1 [Name] => george  [Number] => 437439742 [Email] => hds@gmail.com) 

stdClass Object ( [id] => 2 [Name] => tom  [Number] => 4343554643 [Email] => fdhk@gmail.com) 

how can i use a foreach to display all the values e.g : 1 , george , 437...

-Without knowing the name of the properties -> NOT $o["id"];

foreach($object as $o)
{
  echo $o[i];    // doesn't work on objects
}

I tried converting it to arrays , but it will be an array of the objects so i can;t get the inside info.

//$array = array ($object);

You have a couple of options. One is the get_object_vars() function, and another is to cast the object to an array.

foreach (get_object_vars($object) as $var => $val) {
    // ...
}

or

foreach ((array) $object as $var => $val) {
    // ...
}

You can use:

$array = get_object_vars($obj);
