ClanServer

I was not having any luck with searching so if this is a duplicate please let me know rather than downvoting.

I have a script for a game server that fills a database with the character data (name, level, userid and character type).

Rather than deleting the whole sql table each time and recreating it, I have it perform a check on the character data in the table and compare and only update whats different. it all works nicely.

However, A certain few character names are causing issues.

[09-Sep-2017 02:16:34 America/New_York] PHP Notice: Undefined index: 1OO4 in C:\Scripts\charlist.php on line 56 [09-Sep-2017 02:16:34 America/New_York] PHP Notice: Undefined index: 1zxx in C:\Scripts\charlist.php on line 56

That is this part of the script:

if ($current[$charName] !== $level) {

Where $current is an array of all the characters already in the database, I have it populate the array as Name => Level

The characters are in the database but they are not updating due to the error its throwing (as seen above) I tried wrapping $charName in "" but it did not work.

If anyone can provide advice it would be greatly appreciated.

entire script for reference, can see where i've fixed it in here.
