Estoy tratando de reemplazar los caracteres acentuados con los reemplazos normales. A continuación se muestra lo que estoy haciendo actualmente.
$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;
Esto me da:
After Lower: éric cantona
Final: ric cantona
Lo anterior me da ric cantona
que quiero que la salida sea eric cantona
.
¿Alguien puede ayudarme con lo que estoy haciendo mal?

He intentado todo tipo según las variaciones enumeradas en las respuestas, pero lo siguiente funcionó:
$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 );

Para eliminar los signos diacríticos, use iconv:
$val = iconv('ISO-8859-1','ASCII//TRANSLIT',$val);
o
$val = iconv('UTF-8','ASCII//TRANSLIT',$val);
tenga en cuenta que php tiene un error extraño en el sentido de que (¿a veces?) Necesita tener una configuración regional para que estas conversiones funcionen, usando setlocale ().
edición probada, saca todos los signos diacríticos de la caja:
$val = "á|â|à|å|ä ð|é|ê|è|ë í|î|ì|ï ó|ô|ò|ø|õ|ö ú|û|ù|ü æ ç ß abc ABC 123"; echo iconv('UTF-8','ASCII//TRANSLIT',$val);

Acabo de encontrar la respuesta de Lizard que es extremadamente útil, especialmente cuando haces una clasificación. No es hermoso cuántos caracteres necesitamos para decir casi lo mismo;)

En PHP 5.4, la
intl
extensión proporciona una nueva clase llamada Transliterator.Creo que esa es la mejor manera de eliminar los signos diacríticos por dos razones:
Transliterator se basa en ICU, por lo que está utilizando las tablas de la biblioteca de ICU. ICU es un gran proyecto, desarrollado durante el año para proporcionar tablas y funcionalidades integrales. Cualquiera que sea la tabla que desee escribir usted mismo, nunca será tan completa como la de ICU.
En UTF-8, los personajes se pueden representar de manera diferente. Por ejemplo, el carácter ñ podría guardarse como un carácter único (de varios bytes) o como una combinación de caracteres.
˜
(multibyte) (multibyte) yn
. Además de esto, algunos caracteres en Unicode son homógrafos: se ven iguales pero tienen diferentes puntos de código. Por esta razón también es importante normalizar la cadena.Aquí hay un código de muestra, tomado de una vieja respuesta mía :
<?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"; } ?>
Resultado:
El primer argumento de la clase Transliterator realiza la eliminación de signos diacríticos, así como la normalización de la cadena.
fuente
\Transliterator::createFromRules(':: Any-Latin; :: Latin-ASCII; :: NFD; :: [:Nonspacing Mark:] Remove; :: NFC;', \Transliterator::FORWARD)
, hará el trabajohttps://www.php.net/manual/en/transliterator.createfromrules.php
no habla de las "reglas". ¿Dónde podemos encontrar una descripción completa de lo que aceptacreateFromRules()
?Así que encontré esto en la página php.net para la función 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 tiene problemas de codificación, puede obtener algo como este "ZacarÃÂas FerreÃÂra", simplemente decodifique la cadena y use dicho código de arriba.
$string = utf8_decode("ZacarÃÂas FerreÃÂra");
fuente
Esto funcionó para mí:
<?php setlocale(LC_ALL, "en_US.utf8"); $val = iconv('UTF-8','ASCII//TRANSLIT',$val); ?>

$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';
Como puede ver es bastante similar pero lo más importante son los paramas después de la segunda barra de la expresión regular. Cuando una expresión regualr es así
/[someCoolRegex]/ui
lasu
especifica que se debe utilizar Unicode y losi
especifica que es sensible a mayúsculas, He probado mi propia y con la ansewer en este foro hay que decir es más Efectiva costo de utilizar strtr.Espero que alguien lea esta respuesta.

strtolower
solo funciona en cadenas codificadas con iso-8859-1. Podrías probar conmb_strtolower
.O, si tiene que modificar con extensiones multibyte, también puede usar el soporte de transliteración de iconv:
iconv("UTF-8", "ISO-8859-1//TRANSLIT", $text);
Editar:
Parece que fui un poco rápido. Parece que usa iso-8859-1, por lo que su estrategia actual funcionará. Solo necesita escribir las expresiones regulares correctamente. P.ej.:
'/(ð|é|ê|è|ë)/'
no:
'/[ð|é|ê|è|ë]/'

Puede usar la función PHP strtr () para deshacerse de los caracteres acentuados:
$string = "Éric Cantona"; $accented_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' ); $required_str = strtr( $string, $accented_array );

Lo sé, esa pregunta se ha hecho hace mucho tiempo ...
Estaba buscando una solución corta y elegante, pero no pude encontrar satisfacción por dos razones:
Primero, la mayoría de las soluciones existentes reemplazan una lista de personajes por una lista de otros personajes. Desafortunadamente, requiere usar una codificación específica para el archivo de script php en sí, lo que podría no ser deseado.
En segundo lugar, usar iconv parece ser una buena forma, pero no es suficiente, ya que el resultado de un personaje convertido podría ser uno o dos caracteres, o una Excepción fatal.
Entonces escribí esa pequeña función que hace el trabajo:
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); }

Como alternativa (un poco más compleja por naturaleza), eche un vistazo a cómo wordpress elimina el acento. Hice algunos cambios a continuación para que se ejecute de forma independiente sin hacer referencia a las funciones de WordPress.
function mbstring_binary_safe_encoding($reset = false) { static $encodings = array(); static $overloaded = null; if (is_null($overloaded)) { $overloaded = function_exists('mb_internal_encoding') && (ini_get('mbstring.func_overload') & 2); } if (false === $overloaded) { return; } if (!$reset) { $encoding = mb_internal_encoding(); array_push($encodings, $encoding); mb_internal_encoding('ISO-8859-1'); } if ($reset && $encodings) { $encoding = array_pop($encodings); mb_internal_encoding($encoding); } } function seems_utf8($str) { mbstring_binary_safe_encoding(); $length = strlen($str); mbstring_binary_safe_encoding(true); for ($i = 0; $i < $length; $i++) { $c = ord($str[$i]); if ($c < 0x80) { $n = 0; } // 0bbbbbbb elseif (($c & 0xE0) == 0xC0) { $n = 1; } // 110bbbbb elseif (($c & 0xF0) == 0xE0) { $n = 2; } // 1110bbbb elseif (($c & 0xF8) == 0xF0) { $n = 3; } // 11110bbb elseif (($c & 0xFC) == 0xF8) { $n = 4; } // 111110bb elseif (($c & 0xFE) == 0xFC) { $n = 5; } // 1111110b else { return false; } // Does not match any model for ($j = 0; $j < $n; $j++) { // n bytes matching 10bbbbbb follow ?

Encontré que esta manera es buena, sin tener que preocuparme demasiado por conjuntos de caracteres y matrices:
function replace_accents($str) { $str = htmlentities($str, ENT_COMPAT, "UTF-8"); $str = preg_replace('/&([a-zA-Z])(uml|acute|grave|circ|tilde);/','$1',$str); return html_entity_decode($str); }

Puedes probar este
class Diacritic { public function replaceDiacritic($input) { $input = iconv('UTF-8','ASCII//TRANSLIT',$input); $input = preg_replace("/['|^|`|~|]/","",$input); $input = preg_replace('/["]/','',$input); return preg_replace('/[" "]/','_',$input); } }
