How can a beginner in PHP programming transition from basic tasks like "Hello World" to more complex database operations efficiently?

To transition from basic tasks like "Hello World" to more complex database operations efficiently, beginners can start by learning about PHP's database functions and SQL queries. They can practice connecting to a database, querying data, inserting records, updating information, and deleting entries. Additionally, utilizing frameworks like Laravel or CodeIgniter can streamline the process of working with databases in PHP. 

<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

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

// Query data from the database
$sql = "SELECT * FROM users";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "id: " . $row["id"]. " - Name: " . $row["name"]. "<br>";
    }
} else {
    echo "0 results";
}

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