php - アポストロフィが正しく表示されない

Question

PHP、MYSQL、HTML で簡単なブログを作成しています。アポストロフィと引用符を表示する際に問題が発生し、(html ページで) 「例」を表示する代わりに「例」が表示されます。エスケープ文字列などを使用していますが、まだ機能していません:( ページ:

<?php
    $servidor = "XX";
    $bd = "XX";
    $usuario = "XX";
    $senha = "XX";

    mysql_connect($servidor, $usuario, $senha) or trigger_error(mysql_error());
    mysql_select_db('a3722962_main') or trigger_error(mysql_error());

    $tutoID = $_GET['tuto'];

    $query = mysql_query("SELECT * FROM tutorials WHERE id = '$tutoID'");

    while($line = mysql_fetch_array($query)) {
        $content          = $line['text'];
        $title            = $line['title'];
        $creator          = $line['creator'];
        $name             = $line['name'];
        $idtest           = $line['id'];
    }
    {echo "$content";}
?>

        echo mysql_error();
    }
