PHP的preg_quote相当于什么？

这是我创建一个从字符串中提取文本的方法:

    public static string f_get_string_between(string text, string start, string end)
    {
        //both these attempts below throw an unrecognized escape sequence error
        //start = "\Q"+start+"\E";
        //end = "\Q"+end+"\E"; 

        Regex regex = new Regex(start + "(.*?)" + end);
        var v = regex.Match(text);
        text = v.Groups[1].ToString();
        return text;
    }
