Remplacement des caractères accentués php
J'essaie de remplacer les caractères accentués par les remplacements normaux. Voici ce que je suis en train de faire.
$string = "Éric Cantona";
$strict = strtolower($string);
echo "After Lower: ".$strict;
$patterns[0] = '/[á|â|à|å|ä]/';
$patterns[1] = '/[ð|é|ê|è|ë]/';
$patterns[2] = '/[í|î|ì|ï]/';
$patterns[3] = '/[ó|ô|ò|ø|õ|ö]/';
$patterns[4] = '/[ú|û|ù|ü]/';
$patterns[5] = '/æ/';
$patterns[6] = '/ç/';
$patterns[7] = '/ß/';
$replacements[0] = 'a';
$replacements[1] = 'e';
$replacements[2] = 'i';
$replacements[3] = 'o';
$replacements[4] = 'u';
$replacements[5] = 'ae';
$replacements[6] = 'c';
$replacements[7] = 'ss';
$strict = preg_replace($patterns, $replacements, $strict);
echo "Final: ".$strict;
Cela me donne:
After Lower: éric cantona
Final: ric cantona
Ce qui précède me donne ric cantona Je veux que la sortie soit eric cantona.
quelqu'un peut-il m'aider avec où je vais mal?
J'ai essayé toutes les sortes en fonction des variantes énumérées dans les réponses, mais les suivantes ont fonctionné:
$unwanted_array = array( 'Š'=>'S', 'š'=>'s', 'Ž'=>'Z', 'ž'=>'z', 'À'=>'A', 'Á'=>'A', 'Â'=>'A', 'Ã'=>'A', 'Ä'=>'A', 'Å'=>'A', 'Æ'=>'A', 'Ç'=>'C', 'È'=>'E', 'É'=>'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', 'Ø'=>'O', 'Ù'=>'U',
'Ú'=>'U', 'Û'=>'U', 'Ü'=>'U', 'Ý'=>'Y', 'Þ'=>'B', 'ß'=>'Ss', 'à'=>'a', 'á'=>'a', 'â'=>'a', 'ã'=>'a', 'ä'=>'a', 'å'=>'a', 'æ'=>'a', 'ç'=>'c',
'è'=>'e', 'é'=>'e', 'ê'=>'e', 'ë'=>'e', 'ì'=>'i', 'í'=>'i', 'î'=>'i', 'ï'=>'i', 'ð'=>'o', 'ñ'=>'n', 'ò'=>'o', 'ó'=>'o', 'ô'=>'o', 'õ'=>'o',
'ö'=>'o', 'ø'=>'o', 'ù'=>'u', 'ú'=>'u', 'û'=>'u', 'ý'=>'y', 'þ'=>'b', 'ÿ'=>'y' );
$str = strtr( $str, $unwanted_array );
Pour supprimer les signes diacritiques, utilisez iconv:
$val = iconv('ISO-8859-1','ASCII//TRANSLIT',$val);
ou
$val = iconv('UTF-8','ASCII//TRANSLIT',$val);
notez que php a un bogue étrange dans le sens où il doit (parfois?) avoir un environnement local défini pour que ces conversions fonctionnent, en utilisant setlocale ().
edit juste testé, il récupère la plupart de vos signes diacritiques:
$val = "á|â|à|å|ä ð|é|ê|è|ë í|î|ì|ï ó|ô|ò|ø|õ|ö ú|û|ù|ü æ ç ß abc ABC 123";
echo iconv('UTF-8','ASCII//TRANSLIT',$val);
sortie:
a|a|a|a|a ?|e|e|e|e i|i|i|i o|o|o|?|o|o u|u|u|u ae c ss abc ABC 123
Donc, vous voudrez peut-être corriger ces deux problèmes étranges avant d'appeler iconv, ou vous plonger dans les rouages de PHP et les réparer.
Je viens de trouver la réponse de Lizard qui est extrêmement utile - en particulier lorsque vous effectuez un tri. N'est-ce pas beau combien de caractères nous devons dire la même chose;)

Dans PHP 5.4 l'extension intl fournit une nouvelle classe appelée Transliterator.
Je crois que c'est la meilleure façon de supprimer les signes diacritiques pour deux raisons:
Transliterator est basé sur ICU, vous utilisez donc les tableaux de la bibliothèque ICU. ICU est un excellent projet développé au cours de l'année pour fournir des tableaux complets Quelles que soient les tables que vous souhaitiez écrire vous-même, elles ne seront jamais aussi complètes que celles de ICU.
En UTF-8, les caractères peuvent être représentés différemment. Par exemple, le caractère ñ peut être enregistré en tant que caractère unique (multi-octets) ou en tant que combinaison de caractères
˜(multi-octets) etn. En outre, certains caractères Unicode sont homographes: ils se ressemblent tout en ayant des points de code différents. Pour cette raison, il est également important de normaliser la chaîne.
Voici un exemple de code, tiré de ne de mes anciennes réponses :
<?php
$transliterator = Transliterator::createFromRules(':: NFD; :: [:Nonspacing Mark:] Remove; :: NFC;', Transliterator::FORWARD);
$test = ['abcd', 'èe', '€', 'àòùìéëü', 'àòùìéëü', 'tiësto'];
foreach($test as $e) {
$normalized = $transliterator->transliterate($e);
echo $e. ' --> '.$normalized."\n";
}
?>
Résultat:
abcd --> abcd
èe --> ee
€ --> €
àòùìéëü --> aouieeu
àòùìéëü --> aouieeu
tiësto --> tiesto
Le premier argument de la classe Transliterator supprime les signes diacritiques ainsi que la normalisation de la chaîne.
Cela a fonctionné pour moi:
<?php
setlocale(LC_ALL, "en_US.utf8");
$val = iconv('UTF-8','ASCII//TRANSLIT',$val);
?>
J'ai donc trouvé ceci sur la page php.net pour la fonction preg_replace
// replace accented chars
$string = "Zacarías Ferreíra"; // my definition for string variable
$accents = '/&([A-Za-z]{1,2})(Grave|acute|circ|cedil|uml|lig);/';
$string_encoded = htmlentities($string,ENT_NOQUOTES,'UTF-8');
$string = preg_replace($accents,'$1',$string_encoded);
Si vous avez des problèmes d’encodage, vous risquez d’obtenir quelque chose comme "Zacarès Ferreira", il suffit de décoder la chaîne et d’utiliser le code ci-dessus.
$string = utf8_decode("ZacarÃÂas FerreÃÂra");

Ceci ne mélange pas les caractères majuscules et minuscules sauf pour les caractères plus longs (par exemple: ss, ch, sch), ajouté @ ® ©
De plus, si vous souhaitez créer une correspondance regex indépendamment des caractères spéciaux:
rss => '[rŕřŘŗŖרŔРр](?:[sșсŜšśסşСŝ][sșсŜšśסşСŝ]|[ß])'
Une implémentation vala de ceci: https://code.launchpad.net/~jeremy-munsch/synapse-project/ascii-smart/+merge/277477
Voici la liste de base avec laquelle vous pourriez travailler. Avec le remplacement de regex (dans un texte sublime) ou un petit script, vous pouvez construire n'importe quoi à partir de ce tableau pour répondre à vos besoins.

J'ai cherché et votre idée de bande de l'accent est assez géniale et rentable, mais votre regex est mal faite et manque 2 paramètres supplémentaires. Longue histoire courte la regex doit être:
$patterns[0] = '/[áâàåä]/ui';
$patterns[1] = '/[ðéêèë]/ui';
$patterns[2] = '/[íîìï]/ui';
$patterns[3] = '/[óôòøõö]/ui';
$patterns[4] = '/[úûùü]/ui';
$patterns[5] = '/æ/ui';
$patterns[6] = '/ç/ui';
$patterns[7] = '/ß/ui';
$replacements[0] = 'a';
$replacements[1] = 'e';
$replacements[2] = 'i';
$replacements[3] = 'o';
$replacements[4] = 'u';
$replacements[5] = 'ae';
$replacements[6] = 'c';
$replacements[7] = 'ss';
Comme vous pouvez le constater, la situation est assez similaire, mais le plus important est les paramas après la deuxième barre oblique de l’expression régulière. Quand une expression regualr est comme ceci /[someCoolRegex]/ui le u indique qu’il doit utiliser unicode et le i indique que la casse est respectée, j’ai testé le mien et avec l’ansewer dans ce forum I doit dire est plus économique que d'utiliser strtr.
J'espère que quelqu'un lit cette réponse.
strtolower ne fonctionne que sur les chaînes codées iso-8859-1. Vous pouvez essayer avec mb_strtolower.
Ou, si vous devez utiliser des extensions multi-octets, vous pouvez également utiliser le support de translittération d'iconv:
iconv("UTF-8", "ISO-8859-1//TRANSLIT", $text);
Modifier:
Il semble que j'ai été un peu rapide. Vous semblez utiliser iso-8859-1, votre stratégie actuelle fonctionnera donc. Vous avez juste besoin d'écrire l'expression rationnelle correctement. Par exemple.:
'/(ð|é|ê|è|ë)/'
ne pas:
'/[ð|é|ê|è|ë]/'
Je sais, cette question a été posée il y a très longtemps ...
Je recherchais une solution courte et élégante, mais je ne trouvais pas satisfaction pour deux raisons:
Premièrement, la plupart des solutions existantes remplacent une liste de caractères par une liste d’autres caractères. Malheureusement, il faut utiliser un codage spécifique pour le fichier de script php lui-même, qui pourrait être indésirable.
Deuxièmement, utiliser iconv semble être un bon moyen, mais cela ne suffit pas, le résultat d'un personnage converti pouvant être un ou deux caractères, ou une exception fatale.
Alors j'ai écrit cette petite fonction qui fait le travail:
function replaceAccent($string, $replacement = '_')
{
$alnumPattern = '/^[a-zA-Z0-9 ]+$/';
if (preg_match($alnumPattern, $string)) {
return $string;
}
$ret = array_map(
function ($chr) use ($alnumPattern, $replacement) {
if (preg_match($alnumPattern, $chr)) {
return $chr;
} else {
$chr = @iconv('ISO-8859-1', 'ASCII//TRANSLIT', $chr);
if (strlen($chr) == 1) {
return $chr;
} elseif (strlen($chr) > 1) {
$ret = '';
foreach (str_split($chr) as $char2) {
if (preg_match($alnumPattern, $char2)) {
$ret .= $char2;
}
}
return $ret;
} else {
// replace whatever iconv fail to convert by something else
return $replacement;
}
}
},
str_split($string)
);
return implode($ret);
}
Ajoutant un peu à ce que Lizard disait, cela fonctionnait pour s'afficher correctement sur la page Web, mais ajoutait d'autres codes pour compléter ce que je cherchais pour remplacer mes balises afin de rechercher correctement dans ma base de données avec des caractères spéciaux. Merci d'avance.

En guise d'alternative (un peu plus complexe par nature), regardez comment wordpress supprime les accent. Faites quelques modifications ci-dessous pour le faire fonctionner indépendamment sans faire référence à wordpress fonctions.
