Answer 1

试试这个：

function convert_quotes($string) {
    $string = " " . $string . " "; //add spaces to beginning and end of string to catch strings that begin and/or end with quotes
    $search = array(" '", //use spaces to determine which direction a quote show curl.
                     "' ",
                     "'",
                     ' "',
                     '" '
    );
    $replace = array("‘",
                    "’",
                    "’",
                    "“", 
                    "”"
    );

    return trim(str_replace($search, $replace, $string)); //replace quotes and trim spaces added at beginning of function
}

Answer 2

已经有一个名为"SmartyPants“的插件，最初是由John Gruber创建的，他因”大胆的火球“而出名。它最初是为MoveableType创建的

但其他人已经创建了可供您使用的PHP版本。看看这个：

或者你可以在谷歌上搜索"SmartyPants PHP“，你会找到更多的选项。

同样为了参考，人们也将这些称为“智能引号”。
