Kemarin lagi cari-cari Regex di PHP, sudah lama tidak punya masalah di Regex, karena butuh Panduan Regex di PHP terpaksa search lagi di Om google deh, ni artikel-a.
The following code, the way I understand it, is supposed to strip all punctuation characters from the string. From what I’ve found on the web, a space is not one of those characters. But the code below outputs “abstractmodern.” Would someone please explain how I can strip all special characters except the spaces?
PHP Code:
$pattern = "([[:punct:]])";
$str = "abstract modern";
$str = ereg_replace($pattern, '', $str));
echo $str;
