How can the issue of saving the wrong ID in the database be resolved when selecting multiple options from a dropdown menu in PHP?

When selecting multiple options from a dropdown menu in PHP, the issue of saving the wrong ID in the database can be resolved by ensuring that the selected IDs are stored as an array and properly handled before being saved. This can be achieved by using PHP's `implode()` function to convert the array of IDs into a comma-separated string before saving it to the database. 

// Assuming the selected IDs are stored in an array called $selectedIDs
$selectedIDs = $_POST['selectedIDs']; // Assuming the selected IDs are submitted via POST

// Convert the array of selected IDs into a comma-separated string
$selectedIDsString = implode(',', $selectedIDs);

// Save the comma-separated string of selected IDs to the database
$query = "INSERT INTO table_name (selected_ids) VALUES ('$selectedIDsString')";
// Execute the query using your database connection
