What are the best practices for debugging PHP MySQL queries to avoid syntax errors?

To avoid syntax errors when debugging PHP MySQL queries, it is important to properly format the queries, use prepared statements to prevent SQL injection, and carefully check for any typos or missing quotation marks. Additionally, utilizing error reporting functions in PHP can help identify and resolve syntax errors more efficiently. 

// Example of debugging PHP MySQL queries to avoid syntax errors

// Establish a connection to the MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database");

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

// Example MySQL query with proper formatting and prepared statement
$query = $mysqli->prepare("SELECT * FROM users WHERE id = ?");
$id = 1;
$query->bind_param("i", $id);
$query->execute();
$result = $query->get_result();

// Loop through the results
while ($row = $result->fetch_assoc()) {
    // Output the data
    echo "ID: " . $row['id'] . " | Name: " . $row['name'] . "<br>";
}

// Close the query and database connection
$query->close();
$mysqli->close();
