What are the advantages of using backticks (`) as table or column delimiters in SQL queries generated by PHP scripts?

Using backticks (`) as table or column delimiters in SQL queries generated by PHP scripts ensures that reserved keywords or special characters in table or column names do not cause syntax errors. It also helps improve readability and maintainability of the SQL queries by clearly distinguishing between table/column names and keywords. Additionally, using backticks can prevent potential security vulnerabilities by avoiding SQL injection attacks. 

// Example of using backticks in an SQL query generated by a PHP script
$tableName = "users";
$columnName = "username";

$sql = "SELECT `{$columnName}` FROM `{$tableName}` WHERE `{$columnName}` = 'john_doe'";

// Execute the SQL query using your database connection
$result = mysqli_query($connection, $sql);

// Process the query result as needed
