การแทนที่อักขระเน้นเสียง php

ฉันกำลังพยายามแทนที่อักขระเน้นเสียงด้วยการแทนที่ปกติ ด้านล่างนี้คือสิ่งที่ฉันกำลังทำอยู่

    $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;

สิ่งนี้ทำให้ฉัน:

    After Lower: éric cantona
    Final: ric cantona

ดังกล่าวข้างต้นให้ฉันฉันต้องการที่จะออกric cantonaeric cantona

ใครช่วยบอกทีว่าฉันผิดพลาดตรงไหน

ฉันได้ลองทุกประเภทตามรูปแบบที่ระบุในคำตอบ แต่วิธีต่อไปนี้ใช้ได้ผล:

$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 );

ในการลบตัวกำกับเสียงให้ใช้ iconv:

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

หรือ

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

โปรดทราบว่า php มีข้อผิดพลาดแปลก ๆ ซึ่ง (บางครั้ง?) จำเป็นต้องมีการตั้งค่าภาษาเพื่อให้การแปลงเหล่านี้ทำงานได้โดยใช้ setlocale ()

แก้ไขทดสอบแล้วจะทำให้การกำกับเสียงทั้งหมดของคุณอยู่นอกกรอบ:

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

สังเกตว่าðมีการทับศัพท์อย่างถูกต้องdแทนที่จะoเป็นในคำตอบที่ยอมรับ

ฉันเพิ่งเจอคำตอบจาก Lizard ซึ่งมีประโยชน์มาก - โดยเฉพาะอย่างยิ่งเมื่อคุณทำการจัดเรียงบางอย่าง ไม่สวยเท่าไหร่ที่เราต้องพูดเหมือนกันส่วนใหญ่;)

แก้ไข:รวมอักขระเพิ่มเติมตามการโพสต์จาก user3682119 (ยกเว้นสัญลักษณ์ลิขสิทธิ์) และความคิดเห็นจาก daker

ใน PHP 5.4 intlส่วนขยายจะมีคลาสใหม่ชื่อ Transliterator

ฉันเชื่อว่านั่นเป็นวิธีที่ดีที่สุดในการลบเครื่องหมายกำกับด้วยเหตุผลสองประการ:

1. ตัวทับศัพท์ขึ้นอยู่กับ ICU ดังนั้นคุณจึงใช้ตารางของห้องสมุด ICU ICU เป็นโครงการที่ยอดเยี่ยมซึ่งพัฒนาขึ้นตลอดทั้งปีเพื่อให้มีตารางและฟังก์ชันที่ครอบคลุม ไม่ว่าคุณจะเขียนตารางอะไรด้วยตัวเองมันก็ไม่มีทางสมบูรณ์เท่ากับตารางจาก ICU

2. ใน UTF-8 อักขระอาจแสดงต่างกัน ยกตัวอย่างเช่นตัวอักษร N จะถูกบันทึกไว้เป็นหนึ่งเดียว (สัญลักษณ์) ตัวละครหรือการรวมกันของตัวละคร˜(สัญลักษณ์) nและ นอกจากนี้อักขระบางตัวใน Unicode ยังเป็นคำพ้องเสียง: มีลักษณะเหมือนกันในขณะที่มีจุดรหัสที่แตกต่างกัน ด้วยเหตุนี้การทำให้สตริงปกติจึงเป็นสิ่งสำคัญ

นี่คือโค้ดตัวอย่างที่นำมาจากคำตอบเก่าของฉัน :

<?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";
}
?>

ผลลัพธ์:

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

อาร์กิวเมนต์แรกสำหรับคลาส Transliterator ดำเนินการลบตัวกำกับเสียงเช่นเดียวกับการทำให้เป็นมาตรฐานของสตริง

ดังนั้นฉันจึงพบสิ่งนี้ในหน้า php.net สำหรับฟังก์ชัน 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);

หากคุณมีปัญหาในการเข้ารหัสคุณอาจพบว่า "ZacarÃÂasFerreÃÂra" นี้เพียงแค่ถอดรหัสสตริงและใช้รหัสดังกล่าวข้างต้น

$string = utf8_decode("Zacarías Ferreíra");

สิ่งนี้ใช้ได้ผลสำหรับฉัน:

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

หากคุณมีhttp://php.net/manual/en/book.intl.phpสิ่งนี้จะช่วยแก้ปัญหาของคุณ:

$string = "Éric Cantona";
$transliterator = Transliterator::createFromRules(':: NFD; :: [:Nonspacing Mark:] Remove; :: Lower(); :: NFC;', Transliterator::FORWARD);
echo $normalized = $transliterator->transliterate($string);

อย่าลืมในผู้แต่งต้องใช้ส่วนขยายext-intlเพื่อให้แน่ใจว่าเหมาะสมกับระบบที่ปรับใช้แล้ว

ฉันได้ค้นหาและแนวคิดของคุณสำหรับการเน้นเสียงนั้นค่อนข้างยอดเยี่ยมและคุ้มค่า แต่ regex ของคุณทำผิดพลาดและพลาด 2 พารามิเตอร์พิเศษ เรื่องยาวสั้น regex ต้องเป็น:

$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';

อย่างที่คุณเห็นว่าค่อนข้างคล้ายกัน แต่สิ่งที่สำคัญที่สุดคือพารามาหลังเครื่องหมายทับที่สองของนิพจน์ทั่วไป เมื่อนิพจน์ regualr เป็นเช่นนี้/[someCoolRegex]/uiการuระบุว่าต้องใช้ Unicode และการiระบุว่าไม่คำนึงถึงตัวพิมพ์เล็กและใหญ่ฉันได้ทดสอบของฉันเองและด้วยคำตอบในฟอรัมฉันต้องบอกว่ามีค่าใช้จ่ายมากกว่าการใช้ strtr

หวังว่าจะมีคนอ่านคำตอบนี้

ฉันพบว่าวิธีนี้เป็นวิธีที่ดีโดยไม่ต้องกังวลมากเกินไปเกี่ยวกับชุดอักขระและอาร์เรย์หรือ iconv:

function replace_accents($str) {
   $str = htmlentities($str, ENT_COMPAT, "UTF-8");
   $str = preg_replace('/&([a-zA-Z])(uml|acute|grave|circ|tilde|ring);/','$1',$str);
   return html_entity_decode($str);
}

strtolowerใช้ได้กับสตริงที่เข้ารหัส iso-8859-1 เท่านั้น คุณสามารถลองใช้mb_strtolowerคุณอาจจะลองด้วย

หรือหากคุณต้องยุ่งกับส่วนขยายหลายไบต์คุณอาจใช้การสนับสนุนการทับศัพท์ของ iconv:

iconv("UTF-8", "ISO-8859-1//TRANSLIT", $text);

แก้ไข:

ดูเหมือนว่าฉันจะเร็วไปหน่อย ดูเหมือนคุณจะใช้ iso-8859-1 ดังนั้นกลยุทธ์ปัจจุบันของคุณจึงใช้ได้ผล คุณต้องเขียน regexp ให้ถูกต้อง เช่น.:

'/(ð|é|ê|è|ë)/'

ไม่:

'/[ð|é|ê|è|ë]/'

คุณสามารถใช้ฟังก์ชันPHP strtr ()เพื่อกำจัดอักขระเน้นเสียง:

$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 );

ฉันรู้ว่าคำถามนั้นถูกถามเมื่อนานมาแล้ว ...

ฉันกำลังมองหาวิธีแก้ปัญหาที่สั้นและสง่างาม แต่ไม่พบความพึงพอใจด้วยเหตุผลสองประการ:

ขั้นแรกโซลูชันที่มีอยู่ส่วนใหญ่จะแทนที่รายการอักขระด้วยรายการอักขระอื่น ๆ น่าเสียดายที่ต้องใช้การเข้ารหัสเฉพาะสำหรับไฟล์สคริปต์ php ซึ่งอาจไม่ต้องการ

ประการที่สองการใช้ iconv ดูเหมือนจะเป็นวิธีที่ดี แต่ก็ไม่เพียงพอเนื่องจากผลของอักขระที่แปลงแล้วอาจเป็นอักขระหนึ่งหรือสองตัวหรือข้อยกเว้นร้ายแรง

ดังนั้นฉันจึงเขียนฟังก์ชั่นเล็ก ๆ ที่ใช้งานได้:

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);
}

เป็นอีกทางเลือกหนึ่ง (มีลักษณะที่ซับซ้อนกว่าเล็กน้อย) ลองดูว่า wordpress กำจัดสำเนียงอย่างไร ทำการเปลี่ยนแปลงบางอย่างด้านล่างเพื่อให้ทำงานได้อย่างอิสระโดยไม่ต้องอ้างอิงฟังก์ชัน wordpress
