What are some potential pitfalls when transitioning from querying data from Google to querying data from a database in PHP scripts?

One potential pitfall when transitioning from querying data from Google to querying data from a database in PHP scripts is the difference in syntax and methods used for querying data. To solve this issue, it is important to familiarize yourself with SQL syntax and PHP database functions such as mysqli or PDO. 

// Example of querying data from a database using mysqli

// 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 a table
$sql = "SELECT * FROM table_name";
$result = $conn->query($sql);

// Fetch and display data
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "Column1: " . $row["column1"]. " - Column2: " . $row["column2"]. "<br>";
    }
} else {
    echo "0 results";
}

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