PHP MySQL Get Last Inserted ID

To get the last inserted ID after inserting a record into a MySQL database using PHP, you can use the mysqli_insert_id() function in MySQLi or the lastInsertId() method in PDO.

Here's how to do it for both approaches:

Using MySQLi:

<?php
// MySQLi Configuration
$servername = "localhost"; // Change this to your MySQL server address
$username = "username"; // Change this to your MySQL username
$password = "password"; // Change this to your MySQL password
$database = "dbname"; // Change this to your MySQL database name

// Create connection
$conn = new mysqli($servername, $username, $password, $database);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Data to be inserted
$name = "John Doe";
$email = "john@example.com";

// SQL statement
$sql = "INSERT INTO users (name, email) VALUES (?, ?)";

// Prepare and bind the statement
$stmt = $conn->prepare($sql);
$stmt->bind_param("ss", $name, $email);

// Execute the statement
if ($stmt->execute()) {
    // Get the last inserted ID
    $last_id = $conn->insert_id;
    echo "New record created successfully. Last inserted ID is: " . $last_id;
} else {
    echo "Error: " . $sql . "
" . $conn->error;
}

// Close connection
$stmt->close();
$conn->close();
?>

Using PDO:

<?php
// PDO Configuration
$servername = "localhost"; // Change this to your MySQL server address
$username = "username"; // Change this to your MySQL username
$password = "password"; // Change this to your MySQL password
$database = "dbname"; // Change this to your MySQL database name

// Data to be inserted
$name = "John Doe";
$email = "john@example.com";

try {
    // Connect to MySQL using PDO
    $conn = new PDO("mysql:host=$servername;dbname=$database", $username, $password);
    
    // Set PDO error mode to exception
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    
    // SQL statement
    $sql = "INSERT INTO users (name, email) VALUES (:name, :email)";
    
    // Prepare the statement
    $stmt = $conn->prepare($sql);
    
    // Bind parameters
    $stmt->bindParam(':name', $name);
    $stmt->bindParam(':email', $email);
    
    // Execute the statement
    $stmt->execute();
    
    // Get the last inserted ID
    $last_id = $conn->lastInsertId();
    
    echo "New record created successfully. Last inserted ID is: " . $last_id;
} catch(PDOException $e) {
    echo "Error: " . $e->getMessage();
}

// Close connection
$conn = null;
?>
