Slug 功能在我的主机上不起作用 - 删除了特殊字符

Slug function not working on my host - special characters removed

本文关键字：删除 特殊字符 不起作用 功能 我的 主机 Slug | 更新日期: 2023-09-27

我有一个奇怪的问题，使用slug函数从某个字符串创建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：圣马丁库韦德诺修道院

但是，当我将脚本上传到其他主机的另一个网络空间时，它工作正常！输出应该是：圣马丁

修道院

有什么解释是怎么发生的吗？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，但在我的其他主机上它可以工作，并且设置完全相同，除了： iconv 库版本 2.5

来自phpinfo（）的信息：图标

已启用 iconv 支持iconv 实现 glibciconv 库版本 2.11.3

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

您很可能在服务器上没有iconv。如果您不容易安装它，您可以使用字符翻译 - 有许多解决方案。这是WordPress与附加代码一起使用的那个。代码来自这个SO帖子

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

由于您的文本是法语，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：

  • 列出我绝对想翻译的字符
  • 创建相应的 URL 安全 ASCII 字符列表。
  • 所有剩余的无法识别的字符都通过正则表达式消除

此外，您可以指定单词分隔符，可以选择允许大写字符，删除所有 HTML 标记，并删除所有尾随和双倍单词分隔符。
