PHP如何转换或删除字符串中的特殊字符？

Question

我想要将任何特殊字符转换为它的原始值，我正在尝试这个函数，但它不起作用。这是我的代码。

  $text = "Tuscaloosa County – Hunting and Timber Invest";

  echo $html = mb_convert_encoding($text, "HTML-ENTITIES", "UTF-8");

Answer 1

我不知道这是不是你想要的，但试一试

$text = "Tuscaloosa County – Hunting and Timber Invest"; echo $html =mb_convert_encoding($text, 'UTF-8');

Answer 2

尝试此清理函数

function clean($string) {
       $string = str_replace(' ', '-', $string); // Replaces all spaces with hyphens.

       return preg_replace('/[^A-Za-z0-9\-]/', '', $string); // Removes special chars.
    }
     $text = "Tuscaloosa County – Hunting and Timber Invest";

      echo $html = clean($text);

Answer 3

1。尝试使用next：

 $text = "Tuscaloosa County – Hunting and Timber Invest";
$html_1 = utf8_encode($text);
$html_2 = iconv('ISO-8859-1', 'UTF-8', $text);
$html_2 = mb_convert_encoding($text, 'UTF-8', 'ISO-8859-1');

或

 $text = "Tuscaloosa County – Hunting and Timber Invest";
$html_1 = utf8_decode($text);
$html_2 = iconv('UTF-8', 'ISO-8859-1', $text);
$html_2 = mb_convert_encoding($text, 'ISO-8859-1', 'UTF-8');

2。这样的话：

$html= mb_convert_encode($text,'HTML-ENTITIES','UTF-8');
