php+mysql implements data insertion based on the Insert Into statement

This article mainly introduces php mysql to implement data insertion based on the Insert Into statement. Interested friends can refer to it. I hope it will be helpful to everyone.

INSERT INTO statement is used to insert new records into the database table.

Insert data into the database table

The INSERT INTO statement is used to add new records to the database table.

Syntax:

INSERT INTO table_name VALUES (value1, value2,....)

You can also specify the column in which you want to insert data:

INSERT INTO table_name (column1, column2,...) VALUES (value1, value2,....)

Note: SQL statements are not case-sensitive. INSERT INTO is the same as insert into.

In order for PHP to execute this statement, we must use the mysql_query() function. This function is used to send a query or command to the MySQL connection.

Example:

In the previous chapter, we created a table named "Persons" with three columns: "Firstname", "Lastname" and "Age". We will use the same table in this example. The following example adds two new records to the "Persons" table:

Insert the data from the form into the database:

Now, we create an HTML form that can insert the new records Insert into the "Persons" table.
Here is this HTML form:

  
 Firstname:  Lastname:  Age:   
  

When the user clicks the submit button in the HTML form in the example above, the form data is sent to "insert.php". The "insert.php" file connects to the database and retrieves the values from the form through the $_POST variable. Then, the mysql_query() function executes the INSERT INTO statement, and a new record is added to the database table.

The following is the code of the "insert.php" page:
