我有一些困难，处理只为网址生成英文字符的cms，我需要让它适合葡萄牙，一个处理特殊字符的拉丁国家。
创建链接的功能是：
function generateSafeUrls($url = '') {
## normalize accented characters
$url = strtr($url, "\xA1\xAA\xBA\xBF\xC0\xC1\xC2\xC3\xC5\xC7\xC8\xC9\xCA\xCB\xCC\xCD\xCE\xCF\xD0\xD1\xD2\xD3\xD4\xD5\xD8\xD9\xDA\xDB\xDD\xE0\xE1\xE2\xE3\xE5\xE7\xE8\xE9\xEA\xEB\xEC\xED\xEE\xEF\xF0\xF1\xF2\xF3\xF4\xF5\xF8\xF9\xFA\xFB\xFD\xFF\ã", "_ao_AAAAACEEEEIIIIDNOOOOOUUUYaaaaaceeeeiiiidnooooouuuyy");
## further character processing
$url = strtr($url, array("\xC4"=>"Ae", "\xC6"=>"AE", "\xD6"=>"Oe", "\xDC"=>"Ue", "\xDE"=>"TH", "\xDF"=>"ss", "\xE4"=>"ae", "\xE6"=>"ae", "\xF6"=>"oe", "\xFC"=>"ue", "\xFE"=>"th", "\ã"=>"a"));
## make sure its only english and dashes
$search = array("/[^a-zA-Z0-9\/]/", "/--+/");
$replace = array("-", "-");
$url = preg_replace($search, $replace, $url);
## return safe url
return($url);
}
我可以看到该函数用“ - ”替换空格，如果函数将“ç”替换为“ç”，将“ã”替换为“a”等等，那将会很棒。问题是，我对如何制作它没有任何线索。
我不想让你像我一直说的那样工作，给我提示和提示，我将非常感激;）
亲切的问候你们所有人！谢谢！

此功能应该已经这样做了。 \ xE7是“ç”
