What are some best practices for handling SQL queries in PHP scripts like the one discussed in the thread?

Issue: One common best practice for handling SQL queries in PHP scripts is to use prepared statements to prevent SQL injection attacks and improve performance. Fix: 

// Establish a database connection
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "dbname";

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

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

// Prepare and execute a SQL query using prepared statements
$stmt = $conn->prepare("SELECT * FROM table WHERE column = ?");
$stmt->bind_param("s", $value);

$value = "example value";
$stmt->execute();

// Process the results
$result = $stmt->get_result();
while ($row = $result->fetch_assoc()) {
    // Do something with the data
}

// Close the statement and connection
$stmt->close();
$conn->close();
