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?
