Question

I was working on a simple accent stripping function on PHP

$your_data = $_POST["input"];

function stripchar($str) {
                  $char = array(
                      'a'=>'á|à|ặ|â',

                    );

                foreach($char as $stripped_char => $original_char){
                        $str = preg_replace("/($original_char)/i", $stripped_char, $str);
            }
            return $str;
            }

echo stripchar($your_data);

It worked well if I try to echo accented characters (á à ặ â), of which it would return the intended characters (a a a a).

However, when I put into use - taking a string variable from $string = $_POST["input"] from the html file, inputted by the user, the function did not change the accented characters at all.

The html code:

<!DOCTYPE html>
<html>
<body>
  <div class="inputbox">
        <form action="action_page.php" method="post">
                <textarea type="text" name="input" style="width: 100%; height: 200px;"></textarea>
                <input type="submit" name="action" value="Strip" class="button_form">
        </form> 
  </div>
</body>
</html>

I am still quite confused. Tried var_dump the $string variable and it showed up as string variable. I also tested another function that takes accented string in the script again, and it still worked. But not from the string from the input field!

Answer 1

请改为尝试：

function stripAccents($stripAccents){
  return strtr($stripAccents,'àáâãäçèéêëìíîïñòóôõöùúûüýÿÀÁÂÃÄÇÈÉÊËÌÍÎÏÑÒÓÔÕÖÙÚÛÜÝ','aaaaaceeeeiiiinooooouuuuyyAAAAACEEEEIIIINOOOOOUUUUY');
}

Answer 2

我终于找到了答案 - 结果问题不在于服务器端脚本，而是来自客户端 - 特别是来自我的html文件。 html表单只是发送破碎的重音字符串，因此我的php脚本无法按预期处理字符串。

所以我只需在html文件中添加此行<meta charset="UTF-8">，现在一切正常。
