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

Why not put all tags in an array when you are creating them, and later explode the array and add the commas and spaces between the tags.

foreach ( $tags_arr as $tag ) {
    $tags = '<a href="' . $u . 'tag/' . $tag . '/" title="' . $tag . '">' . $tag . '</a>';
    $tagss[] = $tags;
}
$tagss = explode(', ', $tagss);

Answer 2

function info_get_tags($arg)
{
    global $u;
    if (empty($arg)) return '';
    return ltrim(preg_replace('/([^\,]+)/', ' <a href="' . $u . '/${1}/" title="${1}">${1}</a>', $arg));
}

Answer 3

$string = 'html,css,php,mysql,javascript';

puts $string.split(/,/).map { |tag| "<a href=\"tag/#{tag}\">#{tag}</a>"}.join(", ")

result:

<a href="tag/html">html</a>, <a href="tag/css">css</a>, <a href="tag/php">php</a>, <a href="tag/mysql">mysql</a>, <a href="tag/javascript">javascript</a>

Answer 4

Try this short code

$string = 'html,css,php,mysql,javascript';

$string = explode(',', $string);
   foreach( $string as $link){
   echo '<a href="tag/'.$link.'">'.$link.'</a>';
}

Answer 5

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 = '<a href="%s" title="%s">%s</a>';

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

    }

    return implode(', ', $tags);

}

Answer 6

Here's an alternative that uses array_map instead of the foreach loop:

global $u; 
function add_html($tag){
    return('<a href="' . $u . 'tag/' . $tag . '/" title="' . $tag . '">' . $tag .  '</a>');
}
function get_tags($taglist){
    $tags_arr = array_map("add_html", explode( ',' , $taglist));
    return implode(", " , $tags_arr);
}
