删除/转换PHP中的法语口音

Question

从数据库中提取信息或在页面上显示字符串时，如何用拉丁字母（如“ e”）替换诸如“é”等法语的重音符号？

更新：

链接到“ UTF-8贯穿所有”问题的主持人能否将此问题标记为重复，请解释一下该主题如何回答“如何将法语重音字符转换为英语等效字符”的问题？该问题说明了如何在数据库中正确存储法语字符，然后显示它们，这很好，但没有说明如何使用法语重音符号（如“é”或“à”）转换为“ e”和“ a” 。您可能希望例如转换图像文件名，因为Safari无法显示带有法语字符的图像，将其从用户名中删除或出于其他多种原因。

这将适用于从5.2及更高版本开始的PHP版本。使用Wordpress内置函数删除重音（转换为英语等效项，例如从“é”到“ e”），并且不需要特殊的库或扩展名。经过数小时的法语口音故障排除，这是唯一在所有经过测试的情况下都有效的方法由以下3个功能组成，基本用法是：$ str = detect_remove_french（$ str）;# if the word has a french character return the non french onefunction detect_remove_french($str) {&nbsp; &nbsp; # Tentative no french character version&nbsp; &nbsp; $no_french_char = remove_accents($str);&nbsp; &nbsp; # Compare the above to the original str, if they're different it means that indeed the above contained a french&nbsp; &nbsp; # character&nbsp; &nbsp; if(strcmp($no_french_char,$str) != 0) {&nbsp; &nbsp; &nbsp; &nbsp; return $no_french_char; # <- means there WAS a french character detected, so lets return this french char free version&nbsp; &nbsp; }&nbsp; &nbsp; # means the french and tentative no-french are exactly the same, so there was no french characters to begin with&nbsp; &nbsp; # return FALSE&nbsp; &nbsp; else {&nbsp; &nbsp; &nbsp; &nbsp; return false;&nbsp; &nbsp; }}function remove_accents($string) {&nbsp; &nbsp; if ( !preg_match('/[\x80-\xff]/', $string) )&nbsp; &nbsp; &nbsp; &nbsp; return $string;&nbsp; &nbsp; if (seems_utf8($string)) {&nbsp;

试试这个：$original_string = 'test en français : éèêÉ';$accents = 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','Ğ'=>'G', 'İ'=>'I', 'Ş'=>'S', 'ğ'=>'g', 'ı'=>'i', 'ş'=>'s', 'ü'=>'u','ă'=>'a', 'Ă'=>'A', 'ș'=>'s', 'Ș'=>'S', 'ț'=>'t', 'Ț'=>'T');$str_without_accents = strtr($original_string, $accents);echo $str_without_accents;由于过去200年来法国的口音没有变化，因此对这种硬编码列表的“维护”几乎没有关注。
