How can a PHP query be modified to exclude the user viewing the data from the results?

To exclude the user viewing the data from the results in a PHP query, you can add a condition to the query that filters out the user's data based on their unique identifier (such as user ID or username).

// Assuming $userId contains the unique identifier of the user viewing the data
$query = "SELECT * FROM table_name WHERE user_id != $userId";
// Execute the query and fetch results
