modyfikować (uprościć) tytuł tematu do wyświetlania w Url

Question

Tworzę małą tablicę wiadomości w PHP i muszę "uprościć" tytuł tematu, aby wyświetlić go w adresie URL tematu.

Przykłady:

Ceci est un sujet d'exemple staje ceci-est-un-sujet-d-exemple

J'ai été à la plage staje j-ai-ete-a-la-plage

I dislike sp&cial character$ staje i-dislike-spcial-character (jeśli istnieje lepsze tłumaczenie, biorę go)

EDIT 1: Wszystkie ciągi musi być kodowany w UTF-8

EDIT 2: Niedawno dowiedziałem się, że wynik tego typu operacji jest nazywany „ślimak” albo „przyjazne url”

Answer 1

Oto co zrobiłem. Myślę, że omówiłem większość "pospolitych" postaci. Oczywiście, niektórych będzie brakowało.

Answer 2

$title = "what&v3r y0^7 t1#le is"; // Input string 
$title = preg_replace("/[^a-zA-Z0-9\s]/", "", $title); // Removes all non alpha-numeric characters and spaces 
$title = strtolower($title); // Makes the string lowercase 
$title = preg_replace("/\s/", "-", $title); // Replaces the space character with a dash. 
echo $title; // outputs: whatv3r-y07-t1le-is 

Answer 3

Można spróbować iconv() z ASCII//TRANSLIT jako wyjście CharacterSet.

Answer 4

Ostateczne rozwiązanie, stworzone z twoich odpowiedzi:

function simplifierTitre($str) { 

    $table = array(
     'à' => 'a', 'á' => 'a', 'â' => 'a', 'ã' => 'a', 'ä' => 'a', 'å' => 'a', 
     'ă' => 'a', 'ā' => 'a', 'ą' => 'a', 'æ' => 'a', 'ǽ' => 'a', 'þ' => 'b', 
     'ç' => 'c', 'č' => 'c', 'ć' => 'c', 'ĉ' => 'c', 'ċ' => 'c', 'ż' => 'z', 
     'đ' => 'd', 'ď' => 'd', 'è' => 'e', 'é' => 'e', 'ê' => 'e', 'ë' => 'e', 
     'ĕ' => 'e', 'ē' => 'e', 'ę' => 'e', 'ė' => 'e', 'ĝ' => 'g', 'ğ' => 'g', 
     'ġ' => 'g', 'ģ' => 'g', 'ĥ' => 'h', 'ħ' => 'h', 'ì' => 'i', 'í' => 'i', 
     'î' => 'i', 'ï' => 'i', 'į' => 'i', 'ĩ' => 'i', 'ī' => 'i', 'ĭ' => 'i', 
     'ı' => 'i', 'ĵ' => 'j', 'ķ' => 'k', 'ĸ' => 'k', 'ĺ' => 'l', 'ļ' => 'l', 
     'ľ' => 'l', 'ŀ' => 'l', 'ł' => 'l', 'ñ' => 'n', 'ń' => 'n', 'ň' => 'n', 
     'ņ' => 'n', 'ŋ' => 'n', 'ʼn' => 'n', 'ò' => 'o', 'ó' => 'o', 'ô' => 'o', 
     'õ' => 'o', 'ö' => 'o', 'ø' => 'o', 'ō' => 'o', 'ŏ' => 'o', 'ő' => 'o', 
     'œ' => 'o', 'ð' => 'o', 'ŕ' => 'r', 'ř' => 'r', 'ŗ' => 'r', 'š' => 's', 
     'ŝ' => 's', 'ś' => 's', 'ş' => 's', 'ŧ' => 't', 'ţ' => 't', 'ť' => 't', 
     'ù' => 'u', 'ú' => 'u', 'û' => 'u', 'ü' => 'u', 'ũ' => 'u', 'ū' => 'u', 
     'ŭ' => 'u', 'ů' => 'u', 'ű' => 'u', 'ų' => 'u', 'ŵ' => 'w', 'ẁ' => 'w',

     'ź' => 'z', 
    ); 

    // We don't deal with uppercase characters 
    $str = mb_strtolower($str); 
    // Strip accents 
    $str = strtr($str, $table); 
    // Non-alphanumericals characters become spaces 
    $str = preg_replace('/[^a-z0-9]/', ' ', $str); 
    // Remove trailing and ending spaces 
    $str = trim($str); 
    // Spaces become - 
    $str = preg_replace('#\s+#', '-', $str); 

    return $str; 
} 

Można użyć mniejszej tablicy:

$table = array(
    'à' => 'a', 'á' => 'a', 'â' => 'a', 'ã' => 'a', 'ä' => 'a', 
    'ç' => 'c', 'è' => 'e', 'ê' => 'e', 'ë' => 'e', 'ì' => 'i', 
    'í' => 'i', 'î' => 'i', 'ï' => 'i', 'ñ' => 'n', 'ò' => 'o', 
    'ó' => 'o', 'ô' => 'o', 'õ' => 'o', 'ö' => 'o', 'ù' => 'u', 
    'ú' => 'u', 'û' => 'u', 'ü' => 'u', 'ý' => 'y', 'ÿ' => 'y' 
);
