str_replace - substring php
cómo reemplazar caracteres especiales con los que están basados en PHP? (8)
¿Cómo reemplazo?
- "ã" con "a"
- "é" con "e"
en PHP? es posible? He leído en algún lugar que podría hacer algunas matemáticas con el valor ascii del personaje base y el valor ascii del acento, pero no puedo encontrar ninguna referencia ahora.
La gente a menudo usa str_replace o strtr y una gran lista de caracteres para convertir "de" y "a", incluso si eso no parece muy bonito ...
Otra solución, supongo, podría ser usar algo como iconv con la opción //TRANSLIT - pero no siempre funciona, por lo que recuerdo ...
Además, si está utilizando PHP 5.3, la nueva clase de Normalizer podría ser interesante ;-)
Si no tiene acceso a la clase Normalizer o simplemente no desea usarla, puede usar la siguiente función para reemplazar la mayoría (¿todas?) De las acentuaciones comunes.
function Unaccent($string)
{
return 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''));
}
Especialmente cuando los textos coinciden uno contra el otro o contra palabras clave, es útil normalizar los textos antes. La siguiente función elimina todos los signos diacríticos (marcas como acentos) de un texto codificado en UTF8 dado y devuelve ASCii-text.
Asegúrese de tener instalada la extensión PHP-Normalizer (intl e icu).
Sugerencia: también puede querer asignar el texto a minúsculas antes de ejecutar procedimientos de coincidencia ...
<?php

La función anterior se basa principalmente en el siguiente artículo: http://ahinea.com/en/tech/accented-translate.html
usa PEAR I18N_UnicodeNormalizer-1.0.0
include(''…'');
echo preg_replace(
''/(/P{L})/ui'', // replace all except members of Unicode class "letters", case insensitive
'''', // with nothing
I18N_UnicodeNormalizer::toNFKD(''ÅÉÏÔÙåéïôù'') // ù → u + `
);
→ AEIOUaeiou
Si ninguna de las otras soluciones funciona bien para usted, esto es lo que funcionó para mí:
<?php
$string = "áéíóúÁ—whatever";
// create an array of the hex codes of the characters you want to replace (formatted as shown) and whatever you want to replace them with.
$characters = array(
"[/xF3]" => "&ocacute;", //ó
"[/xFC]" => "ü", //ü
"[/xF1]" => "ñ", //ñ
"[/xEB]" => "ë", //ë
"[/xE9]" => "é", //é
"[/xBD]" => "½", //½
);
// note that you must use a two-digit hex code for whatever reason.
// So, for example, although the hex code for an em dash is 2014, you have to use 97 instead. ("[/x97]" => "—")
// separate the key->value array into two separate arrays. Or just make two arrays from the beginning, but it''s easier to read this way.
foreach ($characters as $hex => $html) {
$replaceThis[] = $hex;
$replaceWith[] = $html;
}
$string = preg_replace($replaceThis, $replaceWith, $string);
?>
Puede que no sea la solución más elegante, pero funciona y no requiere conocimiento de expresiones regulares.
Para aquellos que no tienen php 5.3, encontré otra solución que funciona bien y parece muy completa. Aquí hay un enlace al sitio web del autor http://www.evaisse.net/2008/php-translit-remove-accent-unaccent-21001 . Aquí está la función.
/**

$replaced_string = str_replace($some_special_chars, $replacement_chars, $original_string);
echo $replaced_string; // outputs ''¿Donde esta el nino que vive aqui? En el tempano o en el iglu. AFRICA, MEXICO, INDICE, CANCION y NUMERO.''
?>
Esta respuesta es incorrecta. No entendí la Normalización Unicode cuando lo escribí. Mira el comentario y el enlace de francadaval
Mira la clase de Normalizador para hacer esto. La documentación es buena, así que solo la vincularé en lugar de repetir cosas aquí:
http://www.php.net/manual/en/class.normalizer.php
Específicamente, el miembro normalizado de esa clase:
http://www.php.net/manual/en/normalizer.normalize.php
Tenga en cuenta que la normalización de Unicode tiene varias formas, y parece que desea la Descomposición de Compatibilidad del Formulario de Normalización KD (NFKD), aunque debe leer la documentación para asegurarse.
No debe intentar ejecutar su propia función para esto: hay demasiadas cosas que pueden salir mal, y usar la función provista es una idea mucho mejor.
