php - Slug 功能在我的主机上不起作用 - 删除了特殊字符

Question

我有一个奇怪的问题，使用 slug 函数从某个字符串创建一个 slug。

function createSlug($str, $replace=array(), $delimiter='-') {
    setlocale(LC_ALL, 'en_US.UTF8');
    if( !empty($replace) ) {
        $str = str_replace((array)$replace, ' ', $str);
    }
    $clean = iconv('UTF-8', 'ASCII//TRANSLIT', $str);
    $clean = preg_replace("/[^a-zA-Z0-9\/_|+ -]/", '', $clean);
    $clean = strtolower(trim($clean, '-'));
    $clean = preg_replace("/[\/_|+ -]+/", $delimiter, $clean);
    //strip extra slashes
    $clean = str_replace('/', '-', $clean);
    return $clean;
}

echo createSlug("Abbaye de Saint-Martin Cuvée de Noël.");

结果：abbaye-de-saint-martin-cuve-de-nol

但是，当我将脚本上传到不同主机的另一个网站空间时，它工作正常！输出应该是：abbaye-de-saint-martin-cuvee-de-noel

有什么解释怎么会发生的？我只是使用上传到主机根文件夹的相同脚本。

更新：

iconv 已启用，但它没有使用 UTF-8，我这样做了，但在我的其他主机上它可以工作，并且设置完全相同，除了这个：iconv 库版本 2.5

来自 phpinfo() 的信息：iconv

iconv 支持已启用 iconv 实现 glibc iconv 库版本 2.11.3

指令本地值主值 iconv.input_encoding ISO-8859-1 ISO-8859-1 iconv.internal_encoding ISO-8859-1 ISO-8859-1 iconv.output_encoding ISO-8859-1 ISO-8859-1

Answer 1

这是我用于法语 UTF-8 文本的 slug 函数。它不依赖，iconv因为我很久以前在共享主机上使用它，没有机会安装它。

由于您的文字是法语，这可能会对您有所帮助。我已经评论了该功能，但总体思路是：

• 列出我绝对想转译的字符
• 制作相应的 url-safe ascii 字符列表。
• 通过正则表达式消除所有剩余的无法识别的字符

此外，您可以指定单词分隔符，您可以选择允许使用大写字符，删除所有 HTML 标记并删除所有尾随和双字分隔符。

function createSlug( $str = '', $allowUppercase = 0, $separator = '-' )
{
    // Illegal chars contains non-French characters that my be encountered in French text with names of foreign authors
    $illegal = array( ' ', ' ', '#160;', '&', '—', '–', '\'', '/', ',', '&', '...', '?', '!', '(', ')', ' ', '…', '’', '.', ':', 'à', 'á', 'â', 'ã', 'ä', 'å', 'ò', 'ó', 'ô', 'õ', 'ö', 'ø', 'è', 'é', 'ê', 'ë', 'ç', 'ì', 'í', 'î', 'ï', 'ù', 'ú', 'û', 'ü', 'ÿ', 'ñ', 'œ', 'æ', '%', '"' );
    $illegalUc = array( 'À', 'Á', 'Â', 'Ã', 'Ä', 'Å', 'Ò', 'Ó', 'Ô', 'Õ', 'Ö', 'Ø', 'È', 'É', 'Ê', 'Ë', 'Ç', 'Ì', 'Í', 'Î', 'Ï', 'Ù', 'Ú', 'Û', 'Ü', 'Ÿ', 'Ñ', 'Œ', 'Æ' );

    // Corresponding list of chaaracters/words to replace illegal chars
    $legal = array( $separator, $separator, $separator, $separator, $separator, $separator, $separator, $separator, $separator, $separator, $separator, $separator, $separator, $separator, $separator, $separator, $separator, $separator, $separator, $separator, 'a', 'a', 'a', 'a', 'a', 'a', 'o', 'o', 'o', 'o', 'o', 'o', 'e', 'e', 'e', 'e', 'c', 'i', 'i', 'i', 'i', 'u', 'u', 'u', 'u', 'y', 'n', 'oe', 'ae', $separator.'pourcent'.$separator, $separator );
    $legalUc = array( 'A', 'A', 'A', 'A', 'A', 'A', 'O', 'O', 'O', 'O', 'O', 'O', 'E', 'E', 'E', 'E', 'C', 'I', 'I', 'I', 'I', 'U', 'U', 'U', 'U', 'Y', 'N', 'OE', 'AE' );

    $str = strip_tags( $str ); // remove all HTML tags

    if( $allowUppercase )
    {
        $illegal = array_merge( $illegal, $illegalUc );
        $legal = array_merge( $legal, $legalUc );
    }

    if( !$allowUppercase )
    {
        $str = mb_strtolower( $str, 'UTF-8' );
    }
    $str = str_replace( $illegal, $legal, $str ); // The main translit using our 2 lists

    // Strip all other illegal characters
    $pattern = '/[^A-Za-z0-9]/ui'; // Unicode, case insensitive

    $str = preg_replace( $pattern, $separator, $str );

    // Reduce all double separators to single ones
    while( ( strpos( $str, $separator.$separator ) !== false ) )
    {
        $str = str_replace( $separator.$separator, $separator, $str );
    }

    // Remove any trailing separator
    $str = ltrim( $str, $separator );
    $str = rtrim( $str, $separator );

    return $str; // the string is returned with or without changes
}

您很可能在服务器上没有 iconv。如果您不能轻松安装它，您可以使用字符翻译 - 有很多解决方案。这是 WordPress 在附加代码时使用的那个。代码来自this SO post
