         foreach( $new2old as $key => $value ) {
                $new[] = $key;
                $old[] = $value;
         }
  $text = "Tuscaloosa County – Hunting and Timber Invest";
  echo $html =$string_new = str_replace( $old, $new, $text );

Answer 2

Попробуйте эту функцию очистки

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 . Попробуйте использовать следующее:

 $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');

или

 $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 . И так:

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

Answer 4

Я не знаю, если вы этого хотите, но попробуйте

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