How can the use of backticks in MySQL queries improve code stability and prevent errors in PHP applications?

Using backticks in MySQL queries can improve code stability and prevent errors in PHP applications by properly escaping table and column names. This is important because using backticks ensures that reserved keywords or special characters in the names are handled correctly by the database. Without backticks, queries with special characters or reserved keywords may result in syntax errors or unexpected behavior. 

// Example of using backticks in a MySQL query in PHP
$tableName = 'users';
$columnName = 'username';

$query = "SELECT `{$columnName}` FROM `{$tableName}` WHERE `{$columnName}` = 'john_doe'";
$result = mysqli_query($connection, $query);

if ($result) {
    // Process the result
} else {
    // Handle the error
}
