Replacing accented php characters

Question

I am trying to replace accented characters with a regular replacement. The following is what I am doing now.

$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; 

This gives me:

  After Lower: éric cantona Final: ric cantona 

The above gives me ric cantona I want the result to be eric cantona .

Can someone help me with where I'm wrong?

Answer 1

I tried all kinds based on the options listed in the answers, but the following worked:

 $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 ); 

Answer 2

To remove diacritics, use the icon:

 $val = iconv('ISO-8859-1','ASCII//TRANSLIT',$val); 

or

 $val = iconv('UTF-8','ASCII//TRANSLIT',$val); 

Note that php has some kind of strange error in that it (sometimes?) Must have a locale set to do these conversions using setlocale ().

edit just tested, it gets most of your diacritics out of the box:

 $val = "á|â|à|å|ä ð|é|ê|è|ë í|î|ì|ï ó|ô|ò|ø|õ|ö ú|û|ù|ü æ ç ß abc ABC 123"; echo iconv('UTF-8','ASCII//TRANSLIT',$val); 

exit:

 a|a|a|a|a ?|e|e|e|ei|i|i|io|o|o|?|o|ou|u|u|u ae c ss abc ABC 123 

So, you can manually fix these two odd ones before calling iconv, or delve into the inner workings of php and actually fix it.

Answer 3

I just got a response from Lizard, which is very useful - especially when you do some sorting. Isn't it beautiful how many characters we need to say basically the same;)

If anyone else is looking for a universal solution (as far as indicated above), here is copy & paste:

 /** * Replace language-specific characters by ASCII-equivalents. * @param string $s * @return string */ public static function normalizeChars($s) { $replace = array( ''=>'-', ''=>'-', ''=>'-', ''=>'-', 'Ă'=>'A', 'Ą'=>'A', 'À'=>'A', 'Ã'=>'A', 'Á'=>'A', 'Æ'=>'A', 'Â'=>'A', 'Å'=>'A', 'Ä'=>'Ae', 'Þ'=>'B', 'Ć'=>'C', 'ץ'=>'C', 'Ç'=>'C', 'È'=>'E', 'Ę'=>'E', 'É'=>'E', 'Ë'=>'E', 'Ê'=>'E', 'Ğ'=>'G', 'İ'=>'I', 'Ï'=>'I', 'Î'=>'I', 'Í'=>'I', 'Ì'=>'I', 'Ł'=>'L', 'Ñ'=>'N', 'Ń'=>'N', 'Ø'=>'O', 'Ó'=>'O', 'Ò'=>'O', 'Ô'=>'O', 'Õ'=>'O', 'Ö'=>'Oe', 'Ş'=>'S', 'Ś'=>'S', 'Ș'=>'S', 'Š'=>'S', 'Ț'=>'T', 'Ù'=>'U', 'Û'=>'U', 'Ú'=>'U', 'Ü'=>'Ue', 'Ý'=>'Y', 'Ź'=>'Z', 'Ž'=>'Z', 'Ż'=>'Z', 'â'=>'a', 'ǎ'=>'a', 'ą'=>'a', 'á'=>'a', 'ă'=>'a', 'ã'=>'a', 'Ǎ'=>'a', ''=>'a', ''=>'a', 'å'=>'a', 'à'=>'a', 'א'=>'a', 'Ǻ'=>'a', 'Ā'=>'a', 'ǻ'=>'a', 'ā'=>'a', 'ä'=>'ae', 'æ'=>'ae', 'Ǽ'=>'ae', 'ǽ'=>'ae', ''=>'b', 'ב'=>'b', ''=>'b', 'þ'=>'b', 'ĉ'=>'c', 'Ĉ'=>'c', 'Ċ'=>'c', 'ć'=>'c', 'ç'=>'c', ''=>'c', 'צ'=>'c', 'ċ'=>'c', ''=>'c', 'Č'=>'c', 'č'=>'c', ''=>'ch', ''=>'ch', 'ד'=>'d', 'ď'=>'d', 'Đ'=>'d', 'Ď'=>'d', 'đ'=>'d', ''=>'d', ''=>'D', 'ð'=>'d', 'є'=>'e', 'ע'=>'e', ''=>'e', ''=>'e', 'Ə'=>'e', 'ę'=>'e', 'ĕ'=>'e', 'ē'=>'e', 'Ē'=>'e', 'Ė'=>'e', 'ė'=>'e', 'ě'=>'e', 'Ě'=>'e', 'Є'=>'e', 'Ĕ'=>'e', 'ê'=>'e', 'ə'=>'e', 'è'=>'e', 'ë'=>'e', 'é'=>'e', ''=>'f', 'ƒ'=>'f', ''=>'f', 'ġ'=>'g', 'Ģ'=>'g', 'Ġ'=>'g', 'Ĝ'=>'g', ''=>'g', ''=>'g', 'ĝ'=>'g', 'ğ'=>'g', 'ג'=>'g', 'Ґ'=>'g', 'ґ'=>'g', 'ģ'=>'g', 'ח'=>'h', 'ħ'=>'h', ''=>'h', 'Ħ'=>'h', 'Ĥ'=>'h', 'ĥ'=>'h', ''=>'h', 'ה'=>'h', 'î'=>'i', 'ï'=>'i', 'í'=>'i', 'ì'=>'i', 'į'=>'i', 'ĭ'=>'i', 'ı'=>'i', 'Ĭ'=>'i', ''=>'i', 'ĩ'=>'i', 'ǐ'=>'i', 'Ĩ'=>'i', 'Ǐ'=>'i', ''=>'i', 'Į'=>'i', 'י'=>'i', 'Ї'=>'i', 'Ī'=>'i', 'І'=>'i', 'ї'=>'i', 'і'=>'i', 'ī'=>'i', 'ij'=>'ij', 'IJ'=>'ij', ''=>'j', ''=>'j', 'Ĵ'=>'j', 'ĵ'=>'j', ''=>'ja', ''=>'ja', ''=>'je', ''=>'je', ''=>'jo', ''=>'jo', ''=>'ju', ''=>'ju', 'ĸ'=>'k', 'כ'=>'k', 'Ķ'=>'k', ''=>'k', ''=>'k', 'ķ'=>'k', 'ך'=>'k', 'Ŀ'=>'l', 'ŀ'=>'l', ''=>'l', 'ł'=>'l', 'ļ'=>'l', 'ĺ'=>'l', 'Ĺ'=>'l', 'Ļ'=>'l', ''=>'l', 'Ľ'=>'l', 'ľ'=>'l', 'ל'=>'l', 'מ'=>'m', ''=>'m', 'ם'=>'m', ''=>'m', 'ñ'=>'n', ''=>'n', 'Ņ'=>'n', 'ן'=>'n', 'ŋ'=>'n', 'נ'=>'n', ''=>'n', 'ń'=>'n', 'Ŋ'=>'n', 'ņ'=>'n', 'ʼn'=>'n', 'Ň'=>'n', 'ň'=>'n', ''=>'o', ''=>'o', 'ő'=>'o', 'õ'=>'o', 'ô'=>'o', 'Ő'=>'o', 'ŏ'=>'o', 'Ŏ'=>'o', 'Ō'=>'o', 'ō'=>'o', 'ø'=>'o', 'ǿ'=>'o', 'ǒ'=>'o', 'ò'=>'o', 'Ǿ'=>'o', 'Ǒ'=>'o', 'ơ'=>'o', 'ó'=>'o', 'Ơ'=>'o', 'œ'=>'oe', 'Œ'=>'oe', 'ö'=>'oe', 'פ'=>'p', 'ף'=>'p', ''=>'p', ''=>'p', 'ק'=>'q', 'ŕ'=>'r', 'ř'=>'r', 'Ř'=>'r', 'ŗ'=>'r', 'Ŗ'=>'r', 'ר'=>'r', 'Ŕ'=>'r', ''=>'r', ''=>'r', 'ș'=>'s', ''=>'s', 'Ŝ'=>'s', 'š'=>'s', 'ś'=>'s', 'ס'=>'s', 'ş'=>'s', ''=>'s', 'ŝ'=>'s', ''=>'sch', ''=>'sch', ''=>'sh', ''=>'sh', 'ß'=>'ss', ''=>'t', 'ט'=>'t', 'ŧ'=>'t', 'ת'=>'t', 'ť'=>'t', 'ţ'=>'t', 'Ţ'=>'t', ''=>'t', 'ț'=>'t', 'Ŧ'=>'t', 'Ť'=>'t', '™'=>'tm', 'ū'=>'u', ''=>'u', 'Ũ'=>'u', 'ũ'=>'u', 'Ư'=>'u', 'ư'=>'u', 'Ū'=>'u', 'Ǔ'=>'u', 'ų'=>'u', 'Ų'=>'u', 'ŭ'=>'u', 'Ŭ'=>'u', 'Ů'=>'u', 'ů'=>'u', 'ű'=>'u', 'Ű'=>'u', 'Ǖ'=>'u', 'ǔ'=>'u', 'Ǜ'=>'u', 'ù'=>'u', 'ú'=>'u', 'û'=>'u', ''=>'u', 'ǚ'=>'u', 'ǜ'=>'u', 'Ǚ'=>'u', 'Ǘ'=>'u', 'ǖ'=>'u', 'ǘ'=>'u', 'ü'=>'ue', ''=>'v', 'ו'=>'v', ''=>'v', 'ש'=>'w', 'ŵ'=>'w', 'Ŵ'=>'w', ''=>'y', 'ŷ'=>'y', 'ý'=>'y', 'ÿ'=>'y', 'Ÿ'=>'y', 'Ŷ'=>'y', ''=>'y', 'ž'=>'z', ''=>'z', ''=>'z', 'ź'=>'z', 'ז'=>'z', 'ż'=>'z', 'ſ'=>'z', ''=>'zh', ''=>'zh' ); return strtr($s, $replace); } 

Pay attention to some minor changes regarding German umlauts (ä => ae)

Answer 4

In PHP 5.4, the intl extension provides a new class called Transliterator.

I believe the best way to remove diacritics is for two reasons:

• The transliterator is based on the ICU, so you use the ICU library tables. OIT is an excellent project developed over the course of the year to provide comprehensive tables and functionality. No matter which table you want to write yourself, it will never be as complete as one of the ICUs.

• In UTF-8, characters can be represented in different ways. For example, the character - can be saved as a single (multibyte) character or as a combination of characters ˜ (multibyte) and n . In addition to this, some Unicode characters are a homograph: they look the same with different code points. For this reason, it is also important to normalize the string.

Here is an example of code taken from my old answer :

 <?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"; } ?> 

Result:

 abcd --> abcd èe --> ee € --> € àòùìéëü --> aouieeu àòùìéëü --> aouieeu tiësto --> tiesto 

The first argument for the Transliterator class does the removal of diacritics, as well as the normalization of the string.

Answer 5

So, I found this on the php.net page for the preg_replace function

 // 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); 

If you have problems with the encoding, you may come across such a “ZacarÃÂas FerreÃÂra”, just decrypt the string and use the code above

 $string = utf8_decode("ZacarÃÂas FerreÃÂra"); 

Answer 6

This worked for me:

 <?php setlocale(LC_ALL, "en_US.utf8"); $val = iconv('UTF-8','ASCII//TRANSLIT',$val); ?>

Ħí ŧħə®ë, ßť å test! => Hi there, jusst a test!

This does not mix upper and lower case characters , except for long characters (e.g. ss, ch, sch) added by @ ® ©

Also, if you want to match regular expressions regardless of special characters:
