The current() function is an inbuilt function in PHP.
- It is used to return the value of the element in an array which the internal pointer is currently pointing to.
- The current() function does not increment or decrement the internal pointer after returning the value.
- In PHP, all arrays have an internal pointer. This internal pointer points to some element in that array which is called as the current element of the array.
- Usually, the current element is the first inserted element in the array.
Parameters: The current() function accepts a single parameter $array. It is the array of which we want to find the current element.
Return Values: It returns the value of the element in the array which the internal pointer is currently pointing to. If the array is empty then the current() function returns FALSE.
Input : current(array("John", "b", "c", "d")) Output : John Explanation : Here as we see that input array contains many elements and the ouput is "John" because first element is John and current() function returns the element to which internal pointer is currently pointing. Input: current(array("abc", "123", "7")) Output: abc
