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

Just like you exploded you can implode again:

$tags = explode(',', $arg);
foreach ($tags as &$tag) {
    $tag = '' . $tag . '';
}

return implode(', ', $tags);
