Description
mixed
current ( array &array )
Every array has an internal pointer to its "current" element,
which is initialized to the first element inserted into the
array.
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,
current() returns FALSE.
| Warning |
This function may
return Boolean FALSE, but may also return a non-Boolean value which
evaluates to FALSE, such as 0 or
"". Please read the section on Booleans for more
information. Use the ===
operator for testing the return value of this
function. |
Note:
You won't be able to distinguish the end of an array from a
boolean FALSE element. To properly traverse an array
which may contain FALSE elements, see the each()
function.
Example 1. Example use of current() and friends
<?php
$transport = array('foot', 'bike', 'car', 'plane');
$mode = current($transport); // $mode = 'foot';
$mode = next($transport); // $mode = 'bike';
$mode = current($transport); // $mode = 'bike';
$mode = prev($transport); // $mode = 'foot';
$mode = end($transport); // $mode = 'plane';
$mode = current($transport); // $mode = 'plane';
?>
