Convert comma separated string into array

Question

I have a comma separated string, which consists of a list of tags and want to convert it to array to get a link for every tag.

Example:

$string = \'h         


        

Answer 1

Easiest way is to the html into an array (each tag link is an array element) and then implode on ,...

if ( $arg == '' ) {

    return '';

} else {

    $tags_arr = explode( ',' , $arg );
    $tags  = array();
    $tagtpl = '%s';

    foreach ( $tags_arr as $tag ) {
        $url = $u . 'tag/' . $tag . '/';
        $tags[] = sprintf($tagtpl, $url, $tag, $tag);

    }

    return implode(', ', $tags);

}
