Summary of tp framework development

tp3.2 Documentation http://www.php.cn/xiazai/shouce/31

Usage of capital letters

  • A function is used to instantiate the controller
  • Format: [resource://][module/]controllerA($name,$layer='',$level ='')
    @param string $name 资源地址
    @param string $layer 控制层名称
    @param integer $level 控制器层次
    @return Controller|false

##B executes a certain behavior B($name,$tag='',&$params=NULL)

@param string $name 行为名称
@param string $tag 标签名称(行为类无需传入)
@param Mixed $params传入的参数 @return void
This is a new function that comes into being with the behavior. It can execute a certain behavior, such as B('app_begin');

It is to execute all the functions defined by this behavior before the project starts. It supports 2 Parameters, the second parameter supports the need to accept an array

For example

B('app_begin',array("name"=>"tdweb","time"=>time()));

C Read and set configuration parameters C($name= null,$value=null,$default=null)

@paramstring|array $name 配置变量
@param mixed $value 配置值
@param mixed $default 默认值
@return mixed
Get the value:  

    Get all settings: C(); does not pass any parameters, Returns an array containing all settings.
  • Get the specified configuration: C('URL_MODEL') This way you can get the configuration information of URL_MODEL
  • Get the specified two-dimensional array configuration: C("array.name") This way you can return the array The key under array is the value corresponding to name
Set the value:

    Assign a value to the two-dimensional array C("array.name", "value"), the principle is the same as above (get the value of array.name), the following value is the value
  • Batch assignment:
$test=array("URL_MODEL"=>1,"THIN_MODEL"=>true");
C($test);  这样直接将数组里的值赋值了
  • Judge whether to assign value:

    C("?URL_MODEL")这样前边加个"?",如果已经赋值,则返回true
    It should be noted that, Although the configuration value is changed here, it is only changed on this page, and it will not work on the next page.

    If you want to change it permanently, you need to cooperate with the F function to write the configuration file into config. PHP will do.


  • The D function is used to instantiate the model class format [resource://][module/]model D($name='',$ layer='')

    @param string $name 资源地址
    @param string $layer 模型层名称
    @return Model
    The D function has two advantages:

      First, if this Model has been instantiated before, it will no longer be instantiated, saving resources;
    • The second is to facilitate debugging. If this Model does not exist, a TP exception will be thrown, which is very user-friendly.
    • If you want to access the Model of this project directly, D("Model name"); is fine. If you plan to access across projects, use D("Model name", "Project name");

    EThrow exception handlingE($msg, $code=0)

    @param string $msg异常消息
    @param integer $code 异常代码默认为0
    @return void

    F Fast file data reading and saving For simple type data strings and arrays F($name, $value='',$path=DATA_PATH)

    @param string $name 缓存名称
    @param mixed $value 缓存值
    @param string $path 缓存路径
    @return mixed
      Quickly save data: F("mydata","Here is The data to be saved"), thus saving a file named mydata.php in the project Data directory, and the content inside is the second parameter of the function.
    • Specify the storage time: F("mydata","Here is the data to be saved","60"), so that if the next access is more than 60 seconds, the cache file will be deleted.
    • Specify the saving directory: F("mydata","Here is the data to be saved","60",DATA_PATH), so it is specified to be saved in the data directory.
    • Delete the cache immediately: F("mydata",null), the second parameter passes a null value, so the cache of mydate is deleted
    • Read the cache data: F("mydata"), so the cache is read

    G recording and statistical time (microseconds) and memory usage

    G($start,$end='',$dec=4)
    Usage method:

    G('begin'); // 记录开始标记位 // ... 区间运行代码
    G('end'); // 记录结束标签位
    echo G('begin','end',6); //统计区间运行时间精确到小数后6位
    echo G('begin','end','m'); // 统计区间内存使用情况 如果end标记位没有定义,则会自动以当前作为标记位
    Among them, statistical memory usage is required MEMORY_LIMIT_ON is only valid when the constant is true

    @param string $start 开始标签
    @param string $end 结束标签
    @paraminteger|string $dec小数位或者m
    @return mixed

    I obtain input parameters support filtering and default values

    I($name,$default='',$filter=null)
    Usage method:

    I('id',0); //获取id参数自动判断get或者post
    I('post.name','','htmlspecialchar s'); //获取$_POST['name']
    I('get.'); //获取$_GET

    L() gets and sets the language definition (not case sensitive)

    L($name=null,$value=null)
    @paramstring|array $name 语言变量
    @param mixed $value 语言值或者变量
    @return mixed
    Language definition function, L("intro") gets the language defined as intro, l("intro" , "Introduction") Assign a value to intro


    M function is used to instantiate a Model without a model file

    M($name='',$tablePrefix='',$connection='')
    @param string $name Model名称支持指定基础模型例如MongoModel:User
    @param string $tablePrefix表前缀
    @param mixed $connection  数据库连接信息
    @return Model

    NSet and get statistical data

    N($key,$step=0,$save=false)
    Usage method:

    N('db',1); // 记录数据库操作次数
    N('read',1); // 记录读取次数
    echo N('db'); // 获取当前页面数据库的所有操作次数
    echo N('read'); // 获取当前页面读取次数
    @param string $key 标识位置
    @param integer $step 步进值
    @return mixed

    ##R Remote call controller operation method URL parameter format [resource://] [Module/]Controller/Operation
    R($url,$vars=array(),$layer='')
    @param string $url调用地址
    @paramstring|array $vars调用参数支持字符串和数组
    @param string $layer 要调用的控制层名称
    @return mixed


    Get the template file format resource://module@Theme/Controller/Operation
    T($template='',$layer='')
    @param string $name 模版资源地址
    @param string $layer 视图层(目录)名称
    @return string


    U()URL assembly supports different URL patterns
    U($url='',$vars='',$suffix=true,$domain=false)
    @param string $url URL表达式,格式:'[模块/控制器/操作#锚点@域名]?参数1=值1&参数2=值2...'
    @paramstring|array $vars传入的参数,支持数组和字符串
    @param string $suffix 伪静态后缀,默认为true表示获取配置值
    @paramboolean $domain 是否显示域名
    @return string

    Usage:
    • 取得当前模块的Action地址 :U("/nowMethod");
    • 取得当前模块的Action地址,并传递参数:U("/nowMethod?params=test");
    • (如果不习惯上边那种方式,可以使用U("/nowMethod",array("params"=>"test");这样的数组方式传递参数,效果是一样的)
    • 访问其他模块的方法:U("Other/otherMethod"),这样就是访问Other模块下的otherMethod方法

    跨项目访问:

    U("appname://Other/otherMethod");

    使用路由访问:

    U("appName://routeName@moduleName/actionName?params");

    另外,如果想直接跳转,那么就在第二个参数写1

    U("/nowMethod",1)

    这样就直接调转到指定URL了


    W渲染输出Widget

    W($name,$data=array())
    @param string $name Widget名称
    @param array $data 传入的参数
    @return void

    S缓存管理

    S($name,$value='',$options=null)
    @param mixed $name 缓存名称,如果为数组表示进行缓存设置
    @param mixed $value 缓存值
    @param mixed $options 缓存参数
    @return mixed
    • 全局缓存读写函数,和C类似,不过是直接写成文件,写在Temp目录下,不过在缓存有一点需要注意,
    • 如果缓存名称是aaa,那么缓存生成的文件名称就是md5("aaa")的值。

    技术

    防止xss攻击

    简单的防止

    当网站不涉及复杂的用户交互时,可以对用户所有提交的文本进行htmlspecialchars函数处理。

    • 版本为:3.2
    • 步骤:
      • 一:在项目配置文件中添加配置: 'DEFAULT_FILTER' => 'htmlspecialchars', //默认过滤函数
      • 二: 使用框架带的I方法获取来自用户提交的数据;
    • 例子

      • M('Member')->save(array('content'=>I('post.content')));

    对COOKIE进行IP绑定

    • cookie的信息一但被别人通过XSS攻击获取后也一样等同于把自己的帐号密码给了别人。
    • 对cookie进行IP绑定,(当然也可以获取用户客户端更多的其它信息进行同时绑定)可以根据用户的IP来判断这个cookie是不是来原始授权用户。

    示例

    • 用户设置了自动登录时保存自动登录信息:
      $auto=I('post.auto');//用户设置了自动登录
      if(!empty($auto)){
      cookie('auto',encrypt(serialize($data)));//将登录信息保存到cookie,其中$data里含有加密后的帐号,密码,和用户的IP,这里的cookie已在全局中设置过期日期为一周
      }
    • 用户关闭浏览器再次访问网站时,进行自动登录
      if (!is_login()) {//是否未登录状态?
      $auth=cookie('auto');
          if(!empty($auth)){//是否未有自动登录cookie?
              $data=unserialize(decrypt($auth));
                  if(!empty($data) && !empty($data['username']) && !empty($data['password']) && !empty($data['last_login_ip'])){
                      $user=M('Member')->where(array('username'=>$data['username'],'password'=>$data['password']))->find();
                          if(!empty($user['id'])&&($user['last_login_ip']==get_client_ip())){//cookie帐号密码是否有效?//IP来源是否相同?
                              login_session($user['id'], $user['username'], $data['last_login_ip']);//用户自动登录成功
                          }
                  }
          }
      }
    • 优点:大多数场景下可使被XSS攻击盗取的cookie失效。
    • 缺点:由于IP存在多台电脑共用的可能,对绑定做不到十分精细

    为COOKIE添加httponly配置

    可以保证cookie只在http请求中被传输,而不被页面中的脚本获取,现市面上绝大多数浏览器已经支持。

    HTML5的新特性:

    <iframe src="http://alibaba.com" sandbox>

    为iframe的增加的sandbox属性,可以防止不信任的Web页面执行某些操作.相信这个方法以后会被广泛使用。

    富文本过滤
