What potential issues can arise when using reserved words like "date" in MySQL in PHP code?

When using reserved words like "date" in MySQL in PHP code, potential issues can arise because these words are reserved for specific functions or operations in the database. To solve this issue, you can use backticks (`) around the reserved word to escape it and allow it to be used as a column name in your SQL queries.

$query = "SELECT `date` FROM table_name";
$result = mysqli_query($connection, $query);
