[, bool preserve_keys])
array_reverse() takes input array and returns a new array
with the order of the elements reversed, preserving the keys
if preserve_keys is TRUE.
範例 1. array_reverse()
example
$input = array ("php", 4.0, array ("green", "red"));
$result = array_reverse ($input);
$result_keyed = array_reverse ($input, TRUE);
|
This makes both $result
and $result_keyed have the
same elements, but note the difference between the
keys. The printout of
$result and
$result_keyed will be:
Array
(
[0] = Array
(
[0] = green
[1] = red
)
[1] = 4
[2] = php
)
Array
(
[2] = Array
(
[0] = green
[1] = red
)
[1] = 4
[0] = php
)

注: The second parameter was added in PHP
