What are the potential implications of not using backticks in PHP MySQL queries?

Not using backticks in PHP MySQL queries can lead to syntax errors, especially when column or table names contain reserved keywords or special characters. To avoid this issue, it is recommended to always enclose column and table names in backticks in MySQL queries within PHP code.

// Example of using backticks in a MySQL query in PHP
$query = "SELECT `column_name` FROM `table_name` WHERE `id` = 1";
$result = mysqli_query($connection, $query);
