Definition and Usage
The current() function returns the value of the current element in an array.
Every array has an internal pointer to its "current" element, which is initialized to the first element inserted into the array.
Tip: This function does not move the arrays internal pointer.
Related methods:
- end() - moves the internal pointer to, and outputs, the last element in the array
- next() - moves the internal pointer to, and outputs, the next element in the array
- prev() - moves the internal pointer to, and outputs, the previous element in the array
- reset() - moves the internal pointer to the first element of the array
- each() - returns the current element key and value, and moves the internal pointer forward
