There is a python package called unidecode that I’ve adopted for the askbot Q&A forum, it works well for the latin-based alphabets and even looks reasonable for greek: >>> import unidecode >>> from unidecode import unidecode >>> unidecode(u’διακριτικός’) ‘diakritikos’ It does something weird with asian languages: >>> unidecode(u’影師嗎’) ‘Ying Shi Ma ‘ >>> Does this … Read more
I like the php-slugs code at google code solution. But if you want a simpler one that works with UTF-8: function format_uri( $string, $separator=”-” ) { $accents_regex = ‘~&([a-z]{1,2})(?:acute|cedil|circ|grave|lig|orn|ring|slash|th|tilde|uml);~i’; $special_cases = array( ‘&’ => ‘and’, “‘” => ”); $string = mb_strtolower( trim( $string ), ‘UTF-8’ ); $string = str_replace( array_keys($special_cases), array_values( $special_cases), $string ); $string … Read more

The term ‘slug’ comes from the world of newspaper production. It’s an informal name given to a story during the production process. As the story winds its path from the beat reporter (assuming these even exist any more?) through to editor through to the “printing presses”, this is the name it is referenced by, e.g., … Read more
function Slug($string) { return strtolower(trim(preg_replace(‘~[^0-9a-z]+~i’, ‘-‘, html_entity_decode(preg_replace(‘~&([a-z]{1,2})(?:acute|cedil|circ|grave|lig|orn|ring|slash|th|tilde|uml);~i’, ‘$1’, htmlentities($string, ENT_QUOTES, ‘UTF-8’)), ENT_QUOTES, ‘UTF-8’)), ‘-‘)); } $user=”Alix Axel”; echo Slug($user); // alix-axel $user=”Álix Ãxel”; echo Slug($user); // alix-axel $user=”Álix—-_Ãxel!?!?”; echo Slug($user); // alix-axel
You can look at the Django framework for how they create a “slug” from arbitrary text. A slug is URL- and filename- friendly. The Django text utils define a function, slugify(), that’s probably the gold standard for this kind of thing. Essentially, their code is the following. import unicodedata import re def slugify(value, allow_unicode=False): “”” … Read more
Instead of a lengthy replace, try this one: public static function slugify($text, string $divider=”-“) { // replace non letter or digits by divider $text = preg_replace(‘~[^\pL\d]+~u’, $divider, $text); // transliterate $text = iconv(‘utf-8’, ‘us-ascii//TRANSLIT’, $text); // remove unwanted characters $text = preg_replace(‘~[^-\w]+~’, ”, $text); // trim $text = trim($text, $divider); // remove duplicate divider $text … Read more
This should do what you’re looking for: function clean($string) { $string = str_replace(‘ ‘, ‘-‘, $string); // Replaces all spaces with hyphens. return preg_replace(‘/[^A-Za-z0-9\-]/’, ”, $string); // Removes special chars. } Usage: echo clean(‘a|”bc!@£de^&$f g’); Will output: abcdef-g Edit: Hey, just a quick question, how can I prevent multiple hyphens from being next to each … Read more
A “slug” is a way of generating a valid URL, generally using data already obtained. For instance, a slug uses the title of an article to generate a URL. I advise to generate the slug by means of a function, given the title (or another piece of data), rather than setting it manually. An example: … Read more
