How can the use of backticks or single quotes impact the execution of SQL queries in PHP?

Using backticks or single quotes around table or column names in SQL queries can impact the execution in PHP, especially when dealing with reserved keywords or special characters. To avoid any issues, it's recommended to use backticks to wrap table and column names in SQL queries to ensure they are treated as identifiers rather than keywords. This can help prevent syntax errors and improve the overall security of the application. 

// Incorrect way without backticks or single quotes
$sql = "SELECT id, name FROM users WHERE status = 'active'";

// Correct way with backticks
$sql = "SELECT `id`, `name` FROM `users` WHERE `status` = 'active'";
