thinkphp is an excellent PHP framework that can effectively improve PHP development efficiency. Here, we will demonstrate how to use thinkphp to implement the add, delete, modify, and query functions of mysql database.

1. Connect to the database

In thinkphp, we can use config.php to configure the database. The following is an example:

return?[?
????'database'=>[?
????????'type'???????????=>?'mysql',?
????????'hostname'???????=>?'localhost',?
????????'database'???????=>?'test',?
????????'username'???????=>?'root',?
????????'password'???????=>?'root',?
????????'charset'????????=>?'utf8',?
????]?
];

The above code represents Connect to the local mysql database, the database name is test, the user name is root, the password is root, and the encoding is utf8.

2. Database addition operation

thinkphp provides many convenient methods to operate the database. For database insertion operations, we can use the following code:

$data['name']?=?'thinkphp';?
$data['description']?=?'thinkphp?is?a?php?framework';?
Db::table('test')->insert($data);

The above code inserts data into the database named test by using Db::table. Here we use $data['name'] = 'thinkphp'; $data['description'] = 'thinkphp is a php framework' to set the value of the data.

3. Database query operation

thinkphp provides a very powerful query method. For example, we can use the following code to implement the query:

$data?=?Db::table('test')->where('name','thinkphp')->select();

The above code uses the where condition to filter data, where 'name' is the column name and 'thinkphp' is the value to be filtered. You can then use the select method to query the data.

4. Database update operation

For database update operation, we can use the following code:

Db::table('test')->where('id',1)->update(['name'=>'thinkphp5]);

The above code will change the id of 1 in the test table The column in the record named 'name' is updated with the value 'thinkphp5'.

5. Database deletion operation

For database deletion operation, we can use the following code:

Db::table('test')->where('id',1)->delete();

The above code will delete the id of 1 in the test table Record.

In short, by properly using the functions provided by thinkphp, we can easily implement addition, deletion, modification and query operations of the database.
