array_unique help

[tuna]

if i have an array like this

[code]array(6) {
  [5]=>
  array(1) {
    [0]=>
    string(8) "20060411"
  }
  [4]=>
  array(1) {
    [0]=>
    string(8) "20060407"
  }
  [3]=>
  array(1) {
    [0]=>
    string(8) "20060411"
  }
  [2]=>
  array(1) {
    [0]=>
    string(8) "20060411"
  }
  [1]=>
  array(1) {
    [0]=>
    string(8) "20060407"
  }
  [0]=>
  array(1) {
    [0]=>
    string(8) "20060407"
  }
}[/code]

How would i remove the duplicates using the array_unique function ?

i've tried many ways, and still cant seem to get it
thanks

array(1)=array_unique(array(1)); doesn't work?

[tuna]

the array(x) is the count (how many items in that array)

Try
[code]<?php
$curr_array = array (
  5=>
  array (
    0=>"20060411"
  ),
  4=>
  array (
    0=>"20060407"
  ),
  3=>
  array(
    0=>"20060411"
  ),
  2=>
  array(
    0=>"20060411"
  ),
  1=>
  array(
    0=>"20060407"
  ),
  0=>
  array(
    0=>"20060407"
  )
);
echo '<pre>' . var_export($curr_array,true) . '</pre>';
$new_array = array();
foreach($curr_array as $k => $v)
    $new_array[$k] = serialize($curr_array[$k]);
$curr_array = array();
foreach(array_unique($new_array) as $k => $v)
    $curr_array[$k] = unserialize($new_array[$k]);
echo '<pre>' . var_export($curr_array,true) . '</pre>';
?>[/code]

This has been tested and works.
