How do i do this?

Hello,

I have this:-

PHP Code:

$var = "Community for India"; 


I want it to be like this:-

PHP Code:

$var2= "community, india"; 


So, all I want is to strip the keywords out of the phrase and have them separated with a comma. How do I do this? And can it be done without vbseo.

Thank you

I don't know how to deal with Regular Expressions, so can't use the preg_replace() function.
Going the long way... (though not foolproof)

PHP Code:

<?php

$string = "A Community in Orkut for India";
$stopwords = array('a','an','the','for','is','am','in');
$count = 0;

$word_array = explode(" ", $string);
$word_array = array_map("strtolower", $word_array);

// echo "<pre>" . $string . "\n\n";
// print_r($word_array);

foreach($word_array as $word)
{
    foreach($stopwords as $stop)
    {
        if($word == $stop)
        {
            unset($word_array[$count]);
        }
    }
    $count++;
}

$keywords = implode(", ", $word_array);

// print_r($word_array);
// echo "\n" . $keywords . "</pre>";

?>

$string has A Community in Orkut for India
$keywords has community, orkut, india

Thanks.. it works great.

But I would still like a shorter version of the code using regexp.

thanks
