Supplement common functions of arrays

Current ($ array_name )?? Returns the first element;

Next ($ array_name )?? Move the pointer forward, and then return the new current element;

Each ($ array_name )?? Returns the current element before the pointer moves forward;

Reset ($ array_name )?? Returns the pointer to the first element of the array;

End ($ array_name )?? Move the pointer to the end of the array;

Prev ($ array_name )?? Move the current pointer back and return the new current element, which is opposite to next;

Array_walk ()?? Apply any function to each element of the array;

Count (), sizeof (), array_count_values ()?? Count the number of array elements;

Extract ()?? Create a series of scalar variables using an array;
