The `current()` function returns the value of the current element in the array.
Each array has an internal pointer that points to its 'current' element, initially pointing to the first element inserted into the array.
Tip:This function does not move the internal pointer of the array. To do this, please use next() And prev() Function.
Related methods:
- end() - Points the internal pointer to the last element in the array and outputs
- next() - Points the internal pointer to the next element in the array and outputs
- prev() - Points the internal pointer to the previous element in the array and outputs
- reset() - Points the internal pointer to the first element in the array and outputs
- each() - Returns the key name and value of the current element and moves the internal pointer forward
