Independent grouping:

In Apps, each group is completely independent, including model, controller, view, configuration and function files Wait, you can easily move and uninstall the group.
The standard independent group directory structure is (taking a Home group as an example):

--+ Home Home group directory
├-+ Common group function directory
├-+ Conf group configuration directory
├-+ Lang group language pack directory
├-+ Action group Action Controller directory
├-+ Model grouped Model model directory
├-+ Widget grouped Widget directory
├-+ ORG grouped extended class library directory
├-+ ... other hierarchical directories
└-+ Tpl group template directory

thinkphp output model and configuration

1. Output of ThinkPHP 3 (Key Points)

a. Output on the page through PHP native output methods such as echo

b. Output through the display method

If you want to assign a variable, you can use the assign method

c. Modify the left and right delimiters

Do not modify the configuration items in the configuration file

                     'TMPL_L_DELIM'=>'<{', //Modify the left delimiter

                     'TMPL_R_DELIM'=>'}>', //Modify the right delimiter

2. Model usage of ThinkPHP 3 (Key points)

You need to operate the database in the form of new Model (table name) in the method

                      $m=new Model('User');

$arr=$m->select();

'DB_TYPE'=>'mysql', //Set the database type

'DB_HOST'=>'localhost',//Set the host

'DB_NAME'=>'thinkphp',//Set the database name

'DB_USER'=>'root', //Set the user name

'db_pwd' = & gt; '', // Set the password

'DB_PORT'=>'3306', //Set the port number

'DB_PREFIX'=>'tp_', //Set table prefix

You can also use the DSN method for configuration

        'DB_DSN'=>'mysql://root:@localhost:3306/thinkphp',//Use DSN method to configure database information

If both methods exist at the same time, the DSN method will take priority

There is also a simple and practical model

M() is equivalent to new Model();

$m=M('User');

$arr=$m->select();

The instance of the model can operate the data. The operation of the operation generally is to add, delete, delete, and check the CURD

 

Add -C Create $m->add()

Delete -D Delete $m->delete()

Change -U Update $m->save()

Check -R Read $m->select()

3. Supplementary information (Understanding)

a. The template can traverse the array

             

                                                                                                                                                                                                                  <{$vo.id}>----<{$vo.username}>-----<{$vo.sex}>

                                                                                                       

b. We can turn on page_trace in the debugging function

1. Turn on the debugging function

                                                                                                                                                                                                                                                              //3. Turn on debugging mode

define('APP_DEBUG',true);

2. We need to set up the configuration file and enable page trace

‘SHOW_PAGE_TRACE’=>true,//Open page Trace

Configuration:

'URL_PATHINFO_DEPR'=>'-',//Modify the URL delimiter

'TMPL_L_DELIM'=>'<{', //Modify the left delimiter

'TMPL_R_DELIM'=>'}>', //Modify the right delimiter

'DB_TYPE'=>'mysql', //Set the database type

'DB_HOST'=>'localhost',//Set the host

'DB_NAME'=>'thinkphp',//Set the database name

'DB_USER'=>'root', //Set user name

'DB_PWD'=>'', //Set password

'DB_PORT'=>'3306', //Set the port number

'DB_PREFIX'=>'tp_', //Set table prefix

'DB_DSN'=>'mysql://root:@localhost:3306/thinkphp',//Use DSN method to configure database information

'SHOW_PAGE_TRACE'=>true,//Open page Trace http://w2ks.com/
