The current() function is used to fetch the value of the current element in an array.

Syntax:

current(array_name) 

Parameter:

Type
array_name The input array. Required Array

Return value

The current element of array_name. If the internal array pointer is beyond the end of the elements list or the array is empty, the function returns FALSE.

<?php
$subject= array('Language','English','Math','Science');
