what's wrong with array_unique?

if you want to reindex the array, use array_values

[FD_F]

its for practice

Quick and dirty, use an associative array.

 

<?php
$str = "the brown fox jumped over the white fox";

$NewStr = split(" ", $str);

$uniq = array();
foreach($NewStr as $me)
{
  $uniq[$me] = 1;
}

var_dump(array_keys($uniq));
?>
