not very pretty, took about 1min to knock up xD so theres most likely to be mistakes or easier ways:

PHP Code:


			
$words = 'I took my dog for a walk';
$wordArr = explode(' ', $words);
$cnt = count($wordArr);
$randNumStor = array();
//generate an array of random numbers
//make sure that no duplicates exist
for($i = 0; $i <= $cnt; $i++)
{
    $randNum = rand(0, $cnt);

    while(in_array($randNum, $randNumStor))
    {
        $randNum = rand(0, $cnt);
    }
    $randNumStor[] = $randNum;
}
//display the words based the random numbers in random array
for($j = 0; $j <= $cnt; $j++)
{
    echo $wordArr[$randNumStor[$j]], ' ';
}

hope i havnt got the wrong end of the proverbial stick.

Edit: i think i may have gotten the wrong idea of you probelm, i just quickly scan read it and saw random text, sorry if i have got the wrong idea but still there are some things in that script that you could use
to delete duplicates from an array use array_unique()

for example:

PHP Code:


			
$words2 = 'I I took took my my dog dog for for a a walk walk';

$wordArray2 = array_unique(explode(' ', $words2));

foreach($wordArray2 as $word)
{
    echo $word , ' ';
}

EDIT: no no it appears i have confused myself twice haha reality and fiction have now become a mad twist in my brain hahahahahahaha.... more coffee needed!
