Metóda - array_shift

(PHP 4, PHP 5, PHP 7)

Removes the first element from an array and moves others forward. The function allows using the array as a queue, so it should only be used in the code if we work with the array as a queue. Otherwise, we remove the last element with an unset() function.

Numerical indexes will be renumbered from zero. The function resets an internal pointer to the current element in the array.
