str_replace - substring php

cómo reemplazar caracteres especiales con los que están basados ​​en PHP?

Question

¿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.

Answer 1

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 ;-)

Answer 2

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''));
}

Answer 3

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
function normalizeUtf8String( $s)
{
// Normalizer-class missing!
if (! class_exists("Normalizer", $autoload = false))
return $original_string;
// maps German (umlauts) and other European characters onto two characters before just removing diacritics
$s = preg_replace( ''@/x{00c4}@u'' , "AE", $s ); // umlaut Ä => AE
$s = preg_replace( ''@/x{00d6}@u'' , "OE", $s ); // umlaut Ö => OE
$s = preg_replace( ''@/x{00dc}@u'' , "UE", $s ); // umlaut Ü => UE
$s = preg_replace( ''@/x{00e4}@u'' , "ae", $s ); // umlaut ä => ae
$s = preg_replace( ''@/x{00f6}@u'' , "oe", $s ); // umlaut ö => oe
$s = preg_replace( ''@/x{00fc}@u'' , "ue", $s ); // umlaut ü => ue
$s = preg_replace( ''@/x{00f1}@u'' , "ny", $s ); // ñ => ny
$s = preg_replace( ''@/x{00ff}@u'' , "yu", $s ); // ÿ => yu
// maps special characters (characters with diacritics) on their base-character followed by the diacritical mark
// exmaple: Ú => U´, á => a`
$s = Normalizer::normalize( $s, Normalizer::FORM_D );
$s = preg_replace( ''@/pM@u'' , "", $s ); // removes diacritics
$s = preg_replace( ''@/x{00df}@u'' , "ss", $s ); // maps German ß onto ss
$s = preg_replace( ''@/x{00c6}@u'' , "AE", $s ); // Æ => AE
$s = preg_replace( ''@/x{00e6}@u'' , "ae", $s ); // æ => ae
$s = preg_replace( ''@/x{0132}@u'' , "IJ", $s ); // ? => IJ
$s = preg_replace( ''@/x{0133}@u'' , "ij", $s ); // ? => ij
$s = preg_replace( ''@/x{0152}@u'' , "OE", $s ); // Π=> OE
$s = preg_replace( ''@/x{0153}@u'' , "oe", $s ); // œ => oe
$s = preg_replace( ''@/x{00d0}@u'' , "D", $s ); // Ð => D
$s = preg_replace( ''@/x{0110}@u'' , "D", $s ); // Ð => D
$s = preg_replace( ''@/x{00f0}@u'' , "d", $s ); // ð => d
$s = preg_replace( ''@/x{0111}@u'' , "d", $s ); // d => d
$s = preg_replace( ''@/x{0126}@u'' , "H", $s ); // H => H
$s = preg_replace( ''@/x{0127}@u'' , "h", $s ); // h => h
$s = preg_replace( ''@/x{0131}@u'' , "i", $s ); // i => i
$s = preg_replace( ''@/x{0138}@u'' , "k", $s ); // ? => k
$s = preg_replace( ''@/x{013f}@u'' , "L", $s ); // ? => L
$s = preg_replace( ''@/x{0141}@u'' , "L", $s ); // L => L
$s = preg_replace( ''@/x{0140}@u'' , "l", $s ); // ? => l
$s = preg_replace( ''@/x{0142}@u'' , "l", $s ); // l => l
$s = preg_replace( ''@/x{014a}@u'' , "N", $s ); // ? => N
$s = preg_replace( ''@/x{0149}@u'' , "n", $s ); // ? => n
$s = preg_replace( ''@/x{014b}@u'' , "n", $s ); // ? => n
$s = preg_replace( ''@/x{00d8}@u'' , "O", $s ); // Ø => O
$s = preg_replace( ''@/x{00f8}@u'' , "o", $s ); // ø => o
$s = preg_replace( ''@/x{017f}@u'' , "s", $s ); // ? => s
$s = preg_replace( ''@/x{00de}@u'' , "T", $s ); // Þ => T
$s = preg_replace( ''@/x{0166}@u'' , "T", $s ); // T => T
$s = preg_replace( ''@/x{00fe}@u'' , "t", $s ); // þ => t
$s = preg_replace( ''@/x{0167}@u'' , "t", $s ); // t => t
// remove all non-ASCii characters
$s = preg_replace( ''@[^/0-/x80]@u'' , "", $s );
// possible errors in UTF8-regular-expressions
if (empty($s))
return $original_string;
else
return $s;
}
?>

La función anterior se basa principalmente en el siguiente artículo: http://ahinea.com/en/tech/accented-translate.html

Answer 4

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

Answer 5

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.
$characters = array(
"[/xF3]" => "&ocacute;", //ó
"[/xFC]" => "&uuml;", //ü
"[/xF1]" => "&ntilde;", //ñ
"[/xEB]" => "&euml;", //ë
"[/xE9]" => "&eacute;", //é
"[/xBD]" => "&frac12;", //½
);
// note that you must use a two-digit hex code for whatever reason.
// So, for example, although the hex code for an em dash is 2014, you have to use 97 instead. ("[/x97]" => "&mdash;")
// separate the key->value array into two separate arrays. Or just make two arrays from the beginning, but it''s easier to read this way.
foreach ($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.

Answer 6

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.

/**
* Unaccent the input string string. An example string like `ÀØėÿᾜὨζὅБю`
* will be translated to `AOeyIOzoBY`. More complete than :
* strtr( (string)$str,

* "aaaaaaaaaaaaooooooooooooeeeeeeeecciiiiiiiiuuuuuuuuynn" );
*
* @param $str input string
* @param $utf8 if null, function will detect input string encoding
* @author http://www.evaisse.net/2008/php-translit-remove-accent-unaccent-21001
* @return string input string without accent

Answer 7

Uso de str_replace corto con caracteres personalizados:

<?php
$original_string = "¿Dónde está el niño que vive aquí? En el témpano o en el iglú. ÁFRICA, MÉXICO, ÍNDICE, CANCIÓN y NÚMERO.";
$some_special_chars = array("á", "é", "í", "ó", "ú", "Á", "É", "Í", "Ó", "Ú", "ñ", "Ñ");
$replacement_chars = array("a", "e", "i", "o", "u", "A", "E", "I", "O", "U", "n", "N");
$replaced_string = str_replace($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.''
?>

Answer 8

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.
