Data can be entered into MySQL tables by executing SQL INSERT statement through PHP function mysql_query. Below a simple example to insert a record into employee table.
Let's make a SQL query using the INSERT INTO statement with appropriate values, after that we will execute this insert query through passing it to the PHP mysqli_query() function to insert data in table. Here's an example, which insert a new row to the persons table by specifying values for the first_name, last_name and email fields.
In real application, all the values will be taken using HTML form and then those values will be captured using PHP script and finally they will be inserted into MySQL tables.
In the previous chapter we created an empty table named "MyGuests" with five columns: "id", "firstname", "lastname", "email" and "reg_date". Now, let us fill the table with data.
While doing data insert its best practice to use function get_magic_quotes_gpc() to check if current configuration for magic quote is set or not. If this function returns false then use function addslashes() to add slashes before quotes.
You can also insert multiple rows into a table with a single insert query at once. To do this, include multiple lists of column values within the INSERT INTO statement, where column values for each row must be enclosed within parentheses and separated by a comma.
