PHP替换à-> a,è-> e等特殊字符

Zor*_*kić 42 php decode utf-8 preg-replace

我有php文件signup.php,它将内容从表单(在form.php文件中)保存到MySQL基础.当我想重新格式化输入内容时出现问题.我想解码像à-> a这样的UTF-8字符.

  $first_name=$_POST['first_name'];
  $last_name=$_POST['last_name'];
  $course=$_POST['course'];

  $chain="prêt-à-porter";

$pattern = array("'é'", "'è'", "'ë'", "'ê'", "'É'", "'È'", "'Ë'", "'Ê'", "'á'", "'à'", "'ä'", "'â'", "'å'", "'Á'", "'À'", "'Ä'", "'Â'", "'Å'", "'ó'", "'ò'", "'ö'", "'ô'", "'Ó'", "'Ò'", "'Ö'", "'Ô'", "'í'", "'ì'", "'ï'", "'î'", "'Í'", "'Ì'", "'Ï'", "'Î'", "'ú'", "'ù'", "'ü'", "'û'", "'Ú'", "'Ù'", "'Ü'", "'Û'", "'ý'", "'ÿ'", "'Ý'", "'ø'", "'Ø'", "'œ'", "'Œ'", "'Æ'", "'ç'", "'Ç'");

$replace = array('e', 'e', 'e', 'e', 'E', 'E', 'E', 'E', 'a', 'a', 'a', 'a', 'a', 'A', 'A', 'A', 'A', 'A', 'o', 'o', 'o', 'o', 'O', 'O', 'O', 'O', 'i', 'i', 'i', 'I', 'I', 'I', 'I', 'I', 'u', 'u', 'u', 'u', 'U', 'U', 'U', 'U', 'y', 'y', 'Y', 'o', 'O', 'a', 'A', 'A', 'c', 'C'); 

$chain = preg_replace($pattern, $replace, $chain);

echo $chain; // print pret-a-porter

$first_name =  preg_replace($pattern, $replace, $first_name);

echo $first_name; // does not change the input!?!

为什么它适用于$ chain,但$ first_name或$ last_name不起作用？

我也试试

echo $first_name; // print áááááábéééééébšššš
$trans = array("á" => "a", "é" => "e", "š" => "s");
echo strtr("áááááábéééééébšššš", $trans); // print aaaaaabeeeeeebssss
echo strtr($first_name,$trans);  // print áááááábéééééébšššš

有一个更简单的方法来实现这一点,使用iconv- 从用户注释,这似乎是你想要做的:字符音译

// PHP.net User notes
<?php
    $string = "?ABB?S?B?D";

    echo iconv('UTF-8', 'ISO-8859-1//TRANSLIT', $string);
    // output: [nothing, and you get a notice]

    echo iconv('UTF-8', 'ISO-8859-1//IGNORE', $string);
    // output: ABBSBD

    echo iconv('UTF-8', 'ISO-8859-1//TRANSLIT//IGNORE', $string);
    // output: ABBASABAD
    // Yay! That's what I wanted!
?>

是很认真的跟你的字符编码,所以你保持相同的编码在过程中的各个阶段-前端,表单提交,源文件的编码.PHP和表单中的默认编码是ISO-8859-1,在PHP 5.4之前,它变为UTF8(最后!).

您可以使用一些功能来实现创意.首先来自CakePHP的inflector类,名为slug:

public static function slug($string, $replacement = '_') {
    $quotedReplacement = preg_quote($replacement, '/');

    $merge = array(
        '/[^\s\p{Ll}\p{Lm}\p{Lo}\p{Lt}\p{Lu}\p{Nd}]/mu' => ' ',
        '/\\s+/' => $replacement,
        sprintf('/^[%s]+|[%s]+$/', $quotedReplacement, $quotedReplacement) => '',
    );

    $map = self::$_transliteration + $merge;
    return preg_replace(array_keys($map), array_values($map), $string);
}

它取决于一个self::$_transliteration类似于你在问题中所做的数组 - 你可以在github上看到inflector的源代码.

另一个是我个人使用的功能,来自这里.

function slugify($text,$strict = false) {
    $text = html_entity_decode($text, ENT_QUOTES, 'UTF-8');
    // replace non letter or digits by -
    $text = preg_replace('~[^\\pL\d.]+~u', '-', $text);

    // trim
    $text = trim($text, '-');
    setlocale(LC_CTYPE, 'en_GB.utf8');
    // transliterate
    if (function_exists('iconv')) {
        $text = iconv('utf-8', 'us-ascii//TRANSLIT', $text);
    }

    // lowercase
    $text = strtolower($text);
    // remove unwanted characters
    $text = preg_replace('~[^-\w.]+~', '', $text);
    if (empty($text)) {
        return 'empty_$';
    }
    if ($strict) {
        $text = str_replace(".", "_", $text);
    }
    return $text;
}

什么这些功能做的是音译,创造" 子弹从任意的文本输入,这是使Web应用程序时,在你的工具箱中一个非常非常有用的东西".希望这可以帮助!

谢谢你的回答,问题是我没有在表单中添加"accept-charset ="UTF-8"". (2认同)

字符串$ chain与数组中的字符具有相同的字符编码 - 甚至可能是$ first_name字符串采用不同的编码,因此这些字符不匹配.您可能希望尝试使用多字节字符串函数.

试试mb_convert_encoding.您可能还想尝试使用HTML_ENTITIES作为to_encoding参数,然后您不必担心字符将如何转换 - 它将是非常可预测的.

假设您对此脚本的输入是UTF-8,可能不是一个糟糕的起点......

$first_name = mb_convert_encoding($first_name, "HTML-ENTITIES", "UTF-8");

function CheckLetters($field){
    $letters = [
        0 => "a à á â ä æ ã å ?",
        1 => "c ç ? ?",
        2 => "e é è ê ë ? ? ?",

        10 => "y ? ÿ",
        11 => "z ? ž ?",
    ];
    foreach ($letters as &$values){
        $newValue = substr($values, 0, 1);
        $values = substr($values, 2, strlen($values));
        $values = explode(" ", $values);
        foreach ($values as &$oldValue){
            while (strpos($field,$oldValue) !== false){
                $field = preg_replace("/" . $oldValue . '/', $newValue, $field, 1);
            }

功能简单。将 \'\xc3\x81b\xc3\xa7 \xc3\x89fg\' 等字符串转换为 \'abc_efg\'
