get rid off the repeat word from an array

[kamkam]

Hi;

How could i get rid off the repeat words from an array? Thanks

eg;

$a[]="the , think , this , that , the , their , that , the , the , those";

i just want the array reduce to "the, think, that,those".

use array_unique() function

Use above. But if you were to do this the hard way you could do something like this:

PHP Code:

<?php
$words = array('the', 'think', 'this', 'that', 'the', 'their', 'that', 'the', 'the', 'those');
$uniqueWords = array();
foreach ($words as $word) {
   if (!in_array($word, $uniqueWords)) {
      $uniqueWords[] = $word;
   }
}  
var_dump($uniqueWords);
?>
