How can the "supplied argument is not a valid MySQL result resource" error be resolved in PHP scripts?

The "supplied argument is not a valid MySQL result resource" error occurs when trying to use a MySQL result resource that is not valid, typically due to an issue with the query execution. To resolve this error, you should check the query execution and make sure it is successful before trying to use the result resource.

// Check if the query execution was successful before using the result resource
$result = mysqli_query($connection, $query);
if ($result) {
    // Use the result resource here
} else {
    // Handle the error, such as displaying a message or logging it
    echo "Error: " . mysqli_error($connection);
}
