current — Return the current element in an array

### Description

current(array|object `$array`): mixed

Every array has an internal pointer to its "current" element, which is initialized to the first element inserted into the array.

### Parameters

`array`

  The array.

### Return Values

The current() function simply returns the value of the array element that's currently being pointed to by the internal pointer. It does not move the pointer in any way. If the internal pointer points beyond the end of the elements list or the array is empty, current() returns `false`.

Warning

This function may return Boolean `false`, but may also return a non-Boolean value which evaluates to `false`. Please read the section on Booleans for more information. Use the === operator for testing the return value of this function.

### Changelog

Version | Description
--- | ---
8.1.0 | Calling this function on objects is deprecated. Either convert the object to an array using get_mangled_object_vars() first, or use the methods provided by a class that implements Iterator, such as ArrayIterator, instead.
7.4.0 | Instances of SPL classes are now treated like empty objects that have no properties instead of calling the Iterator method with the same name as this function.

### Examples

Example #1 Example use of current() and friends

`<?php
$transport = array('foot', 'bike', 'car', 'plane');
echo $mode = current($transport), PHP_EOL; // $mode = 'foot';
echo $mode = next($transport), PHP_EOL; // $mode = 'bike';
echo $mode = current($transport), PHP_EOL; // $mode = 'bike';
echo $mode = prev($transport), PHP_EOL; // $mode = 'foot';
echo $mode = end($transport), PHP_EOL; // $mode = 'plane';
echo $mode = current($transport), PHP_EOL; // $mode = 'plane';
$arr = array();
var_dump(current($arr)); // bool(false)
$arr = array(array());
var_dump(current($arr)); // array(0) { }
?>`

### Notes

> Note: The results of calling current() on an empty array and on an array, whose internal pointer points beyond the end of the elements, are indistinguishable from a bool `false` element. To properly traverse an array which may contain `false` elements, see the `foreach` control structure. To still use current() and properly check if the value is really an element of the array, the key() of the current() element should be checked to be strictly different from `null`.
