Are there any specific syntax rules or conventions to follow when writing MySQL queries in PHP?

When writing MySQL queries in PHP, it is important to follow certain syntax rules and conventions to ensure the queries are executed properly. One common rule is to enclose table and column names in backticks (`) to avoid conflicts with reserved keywords. Additionally, using prepared statements with placeholders can help prevent SQL injection attacks and improve query performance. 

// Example of a MySQL query in PHP using backticks and prepared statements

// Establish a connection to the database
$pdo = new PDO('mysql:host=localhost;dbname=my_database', 'username', 'password');

// Prepare a SQL query with placeholders
$stmt = $pdo->prepare("SELECT * FROM `users` WHERE `username` = :username");

// Bind the parameter value to the placeholder
$stmt->bindParam(':username', $username);

// Execute the query
$stmt->execute();

// Fetch the results
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);

// Loop through the results
foreach ($results as $row) {
    // Process the data
}
