Re: How do I get the first element's key of an array of objects?

I have an array of objects in PHP5. Each element's key is the database row ID. I don't see a graceful way of finding the first element's key ID. So I have this... Array (

    [3] => fooObject Object
        (
            [id:protected] => 3
            [model:protected] => ABC
            [read:protected] => public
            [write:protected] => private
        )
    [5] => fooObject Object
        (
            [id:protected] => 5
            [model:protected] => DEF
            [read:protected] => public
            [write:protected] => private
        )

) Etc. I want to get [3] somehow. http://www.php.net/manual/en/function.array-pop.php array_pop() pops and returns the last value of the array, shortening the array by one element. Which is opposite of what I want. http://www.php.net/manual/en/function.array-shift.php Shift an element off the beginning of array But this reduces the array :( My hack is to do this: foreach($fooObject as $key => $object) { $id = $key; break; } There has to be a better way. Something more elegant?

How about reversing the array... http://us4.php.net/manual/en/function.array-reverse.php And then you can use array_pop() OR foreach ( $myArray as $key => $value ) { $theOneIWant = $value; break; } -- John C. Nichel ÜberGeek KegWorks.com 716.856.9675 john@kegworks.com
