PHP Update MySQL from CSV Skip Row on Error - php

Question

So basically, I have a CSV file that will be uploaded but not stored on the server and PHP will pull data from it and update a database accordingly.
My Issue is that I am trying to skip the row in the CSV if there is already an entry found in the database but it stops on the first error and does not skip.
Line 62, I added a comment which is where I am trying to get this accomplished.
the ELSE statement after the if (($update == 1) && ($update2 == 1)) has a continue in it, meaning if update and update2 do not == 1 then skip, or so I would have thought but it just stops after the first duplicate serial number is found.
Any help is GREATLY appreciated

If you want to show all errors, you should use an array, and append the error text to that array. Then use foreach loop on client part to display all errors.
If you use a single variable it will always be what you set it to most recently. For multiple data, you should use an array, or append to string like this: $string .= "appended string"; but for this case I recommend using arrays.
