Inserting data is one of the fundamental operations when working with databases. In this article, I will show you how to perform a data insertion into MySQL using PHP.
What is PHP and MySQL?
Before we begin, it is important to understand what PHP and MySQL are. PHP is a general-purpose programming language especially suitable for web development. On the other hand, MySQL is a very popular database management system used to store and retrieve information.
Step 1: Establish connection to the database
Before we can perform a data insert into MySQL, we must establish a connection to the database. To do this, we will use the function mysqli_connect() of PHP. This function allows us to connect to a MySQL server by specifying the server address, username, password and database name.
Here is an example of how to establish a connection to the database:
<?php
$servername = "localhost";
$username = "root";
$password = "contraseña";
$dbname = "basededatos";
$conn = mysqli_connect($servername, $username, $password, $dbname);
if (!$conn) {
die("Error al conectarse a la base de datos: " . mysqli_connect_error());
}
echo "Conexión exitosa";
?>Step 2: Create the insert query
Once we have established the connection to the database, we can proceed to create the insert query. In this query, we will specify the table in which we want to insert the data and the values we want to insert in each column.
Here is an example of how to create an insert query:
<?php
$sql = "INSERT INTO usuarios (nombre, email, telefono) VALUES ('John Doe', '[email protected]', '123456789')";
if (mysqli_query($conn, $sql)) {
echo "Datos insertados correctamente";
} else {
echo "Error al insertar datos: " . mysqli_error($conn);
}
mysqli_close($conn);
?>Step 3: Run the insert query
Once we have created the insert query, we can execute it using the function mysqli_query() of PHP. This function takes two parameters: the database connection and the insert query.
If the data insertion is successful, the function mysqli_query() will return true. Otherwise it will return false and we can get more information about the error using the function mysqli_error().
Conclusion
In this article, we have learned how to perform data insertion in MySQL using PHP. Always remember to establish a connection to the database, create the correct insert query, and execute it properly. I hope this tutorial is useful to you!
