If I want to limit the maximum number of characters of a keyword, how to? for example, each input keywords only have a maximum of 20 characters
Thanks for points. To limit the length of accepted keywords you can use this:
if (isset($_POST['submit'])){
$kw = $_POST['keywords'];
$kw = preg_replace("/\s+/", " ", $kw);
$kwArr = explode(' ', $kw);
$output = array_slice($kwArr, 5, count($kwArr));
$output = array_diff($kwArr, $output);
for($i = 0; $i<count($output); $i++){
if (strlen($output[$i]) <= 20){
$result[] = $output[$i];
}
}
$keywords = implode(', ', $result);
echo $keywords;
}
