function detect Unicode UTF-8 string PHP

by in 0

Based upon that snippet below using preg_match() I needed something faster and less specific.  That function works and is brilliant but it scans the entire strings and checks that it conforms to UTF-8




function detectUTF8($string)
{
        return preg_match('%(?:
        [\xC2-\xDF][\x80-\xBF]        # non-overlong 2-byte
        |\xE0[\xA0-\xBF][\x80-\xBF]               # excluding overlongs
        |[\xE1-\xEC\xEE\xEF][\x80-\xBF]{2}      # straight 3-byte
        |\xED[\x80-\x9F][\x80-\xBF]               # excluding surrogates
        |\xF0[\x90-\xBF][\x80-\xBF]{2}    # planes 1-3
        |[\xF1-\xF3][\x80-\xBF]{3}                  # planes 4-15
        |\xF4[\x80-\x8F][\x80-\xBF]{2}    # plane 16
        )+%xs', $string);

Tooltips In only CSS3 And HTML5, Without JavaScript

Tooltips in HTML pages general do not need any effort from a developer’s side, as long as they put proper title attributes to their elements. The title is then used for showing the tooltip, but also for other things, such as providing a screen reader with proper content. Speaking of the use case of tooltips, the visual presentation depends on the browser your site gets visited with. Developers with the need for more control turned to JavaScript bases solutions years ago. Kashagra Gour created Hint.css, which proves as a decent alternative, based completely on CSS and HTML.
