[thinkphp] Basics Guide

Independent grouping:

In Apps, each group is completely independent, including models, controllers, views, configuration and function files, etc., which can be easily moved and uninstalled.
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 group Model Model directory
├-+ Widget grouped Widget directory
├-+ ORG grouped extended class library directory
├-+ ... other hierarchical directories
└-+ Tpl grouped template directory

thinkphp output model and configuration

1. Output of ThinkPHP 3 (Key Points)

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

P 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

置 To modify the configuration item in the configuration file

                    'TMPL_L_DELIM'=>'

                    '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

                                                                                                                                                 to                   out’s out's' out’s' out out’s'

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

Or 'db_port' = & gt; '3306', // Set the port number

         'DB_PREFIX'=>'tp_', //Set the 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 method

M() is equivalent to new Model();

          $m=M('User');

             $arr=$m->select();

可以 Use the example of the model to operate the data. The operation of the operation is general

Add -C Create $m->add()

           Delete -D Delete $m->delete()

                                                                                                                                                                                                                      being changed to -U Update $m->save()

Check -R Read $m->select()

3. Supplementary information (understanding)

          a. The template can traverse the array

                                                                                                 调 B. We can turn on the page_trace

              1. Turn on the debugging function

                                                                                                                             

                                                                                                    out

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

_ 'Show_page_trace' = & gt; true, // Open the page trace

Configuration:

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

'TMPL_L_DELIM'=>' '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 username

'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/

The above introduces the [thinkphp] basic guide, including various aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
