Message:

I have an array:

array( 4 => 'apple', 7 => 'orange', 13 => 'plum' )

I would like to get the first element of this array. Expected result: string apple

One requirement: it cannot be done with passing by reference, so array_shift is not a good solution.

How can I do this?

My Answer:
array(4, 8, 15, 16, 23, 42);

To get the first element of the array, you can use the following code:

$firstElement = reset($array);

This code uses the reset() function to move the internal pointer of the array to the first element and returns that element.
