PDO with INSERT INTO through prepared statements

To insert data into a database using PDO and prepared statements, you can use the following steps:

1. Connect to the database using PDO.

Example of inserting data into a database using PDO and prepared statements in PHP

$dbh = new PDO('mysql:host=localhost;dbname=test', $user, $pass);

2. Prepare the SQL statement. This creates a prepared statement and returns a PDOStatement object.

Example of creating a prepared statement and returning a PDOStatement object in PHP

$stmt = $dbh->prepare("INSERT INTO users (name, email) VALUES (:name, :email)");

3. Bind the values to the parameters in the prepared statement. This specifies the values for the parameters in the prepared statement.

Example of binding the values to the parameters in the prepared statement in PHP

$stmt->bindParam(':name', $name);
$stmt->bindParam(':email', $email);

4. Execute the prepared statement. This inserts the data into the database.

Example of executing a prepared statement in PHP

$stmt->execute();

<div class="alert alert-info flex not-prose"> <span class="hidden md:block">Watch a video course </span> Learn object oriented PHP</div>

Here is an example of the complete code:

The complete code of inserting data into a database using PDO and prepared statements in PHP

<?php

$dbh = new PDO('mysql:host=localhost;dbname=test', $user, $pass);
$stmt = $dbh->prepare("INSERT INTO users (name, email) VALUES (:name, :email)");
$stmt->bindParam(':name', $name);
$stmt->bindParam(':email', $email);
$stmt->execute();

This code assumes that you have already established a connection to the database and that you have a valid PDO object stored in the $dbh variable. It also assumes that you have defined the variables $name and $email, which contain the values that you want to insert into the database.
