 */
function array_rand_value(array $array, $numReq = 1)

array_rand_weighted

/**
 * Get a random value from an array, with the ability to skew the results.
 * Example: array_rand_weighted(['foo' => 1, 'bar' => 2]) has a 66% chance of returning bar.
 * 
 * @param array $key
 * 
 * @return mixed
 */
function array_rand_weighted(array $array)

values_in_array

/**
 * Determine if all given needles are present in the haystack.
 *
 * @param array, string $needles
 * @param array $haystack
 *
 * @return bool
 */
function values_in_array($needles, array $haystack)

array_keys_exist

/**
 * Determine if all given needles are present in the haystack as array keys.
 * 
 * @param array, string $needles
 * @param array $haystack
 *
 * @return bool
 */
function array_keys_exist($needles, array $haystack)

array_split_filter

/**
 * Returns an array with two elements.
 * 
 * Iterates over each value in the array passing them to the callback function.
 * If the callback function returns true, the current value from array is returned in the first
 * element of result array. If not, it is return in the second element of result array.
 *
 * Array keys are preserved.
 *
 * @param array $array
 * @param callable $callback
 * @return array
 *
 */
function array_split_filter(array $array, callable $callback)

array_split

/**
 * Split an array in the given amount of pieces.
 *
 * @param array $array
 * @param int $numberOfPieces
 * @param bool $preserveKeys
 * @throws \InvalidArgumentException
 * @return array
 */
function array_split(array $array, $numberOfPieces = 2, $preserveKeys = false)

array_merge_values

/**
 * Returns an array with the unique values from all the given arrays
 *
 * @param \array[] $arrays
 * @return array
 */
function array_merge_values(array ... $arrays)

array_flatten

/**
 * Flatten an array of arrays. The `$levels` parameter specifies how deep you want to
 * recurse in the array. If `$levels` is -1, the function will recurse infinitely.
 *
 * @param array $array
 * @param int $levels
 *
 * @return array
 */
function array_flatten(array $array, $levels = -1)
