How can a beginner effectively learn and understand MySQL commands and syntax for PHP development?

To effectively learn and understand MySQL commands and syntax for PHP development as a beginner, one can start by studying the basics of SQL queries, such as SELECT, INSERT, UPDATE, and DELETE. It is also helpful to practice writing and executing these queries in a MySQL database management tool like phpMyAdmin. Additionally, utilizing resources like online tutorials, documentation, and practice exercises can aid in gaining proficiency with MySQL commands in PHP development.

// Example of executing a SELECT query in PHP using MySQL
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";

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

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

// Execute SELECT query
$sql = "SELECT * FROM table_name";
$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";
}

$conn->close();
