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

Another solution:

$html = trim(preg_replace('/([^,]+)/', ' \1', $string));

Or if you have to html encode the tags (always smart, since you're creating html from text):

$html = trim(preg_replace_callback('/([^,]+)/', function($match) {
    $tag = $match[1];
    return ' ' . htmlspecialchars($tag) . '';
}, $string));

So this $string would work too: "tag with space,html,css,php,mysql,javascript"

More regex is always good!
