this function will return an array with unique value and proper key increment start from 0.
<?php
/*******************************/
function my_array_unique($somearray){
$tmparr = array_unique($somearray);
$i=0;
foreach ($tmparr as $v) {
$newarr[$i] = $v;
$i++;
}
return $newarr;
}
/********************************/
?>
eg:
<?php
$foo_arr[0] ='aa'
$foo_arr[1] ='bb'
$foo_arr[2] ='cc'
$foo_arr[3] ='bb'
$foo_arr[4] ='aa'
$foo_arr[5] ='dd'
?>
normal array_unique will return:
<?php
$foo_arr[0] ='aa';
$foo_arr[1] ='bb';
$foo_arr[2] ='cc';
$foo_arr[3] ='';
$foo_arr[4] ='';
$foo_arr[5] ='dd'
?>
my_array_unique will return:
<?php

$foo_arr[1] ='bb';
$foo_arr[2] ='cc';
$foo_arr[3] ='dd'
?>
