PHP count question

Solution:

Rude comment aside, I believe this is what you are trying to do:

// gets rid of empty tags, 
// trims them and sets them to lowercase
for ($i=0; $i<count($tags); $i++) {
    if (trim($tags[$i]) != '') { // using trim to get rid of spaces
        $tags[$i] = strtolower(strip_tags($tags[$i]));
    } else {  
        unset($tags[$i]); // gets rid of empty tags
    }
}

// print out tags
switch (count($tags)) {
    case 0:
        echo 'no tags entered.';
        break;
    case 1:
        echo $tags[0] . ' tag entered.';
        break;
    default:
        echo implode(', ', $tags) . ' tags entered';
        break;
}
Copy code

Next time, learn to:

• Be more respectful
• Word your question properly, and give examples of expected input and output when necessary

In that order.
