PHP: Separate array with commas [duplicate]

Question

I have this code that should display a list of values from an array followed by a comma and space! However I don't want the last one to have a comma and space after it.

So for example I want tag1, tag2, tag3 instead of tag1, tag2, tag3,

This is my code:

<?php $terms = get_the_terms( $the_post->ID, 'posts_tags' );
                                foreach ( $terms as $term ) {

                                    echo $term->name;echo ", ";
                                } ?>

$output = array();
foreach($terms as $term){
  $output[] = $term->name;
}
echo implode(', ', $output);

Makes me wonder why a language as php and a framework like wordpress do not have any decent library to do even the most basic operations. Rails -> array.join(", ")

@Marek: It does. implode(', ', $array).
