PHP从多维数组中随机选择一个数组[重复]

So I have this array of objects. From which I want to take at random one of the objects from the array, and use it for its intended purpose. I have tried array_rand() but that only returned a random value from one of the arrays within. Is there a method similar to array_rand() that will let me use the whole array as the variable rather than a value pluked from within it?

Example Array:

Array
(
    [0] => stdClass Object
        (
            [id] => 10003
            [state] => CA
        )

    [1] => stdClass Object
        (
            [id] => 10003
            [state] => CA
        )

    [2] => stdClass Object
        (
            [id] => 10006
            [state] => CA
        )
)

What I want to do when doing something similar to array_rand() is end up with a variable that is

[0] => stdClass Object
            (
                [id] => 10006
                [state] => CA
            )

or similar

</div>

From array_rand documentation:

[array_rand] picks one or more random entries out of an array, and returns the key (or keys) of the random entries.

To summarize: if you want to retrieve a random value from an array, you need to use the random key provided by array_rand to access it.

Solution, assuming your array is stored in $obj:

$random_obj = $obj[array_rand($obj));
