PHP: Undefined index even if it exists

Question

It drives me crazy ... I try to parse a csv file and there is a very strange behavior.

Here is the csv

action;id;nom;sites;heures;jours
i;;\"un nom a         


        

Answer 1

If your CSV file is in UTF-8 encoding,

make sure that it's UTF-8 and not UTF-8-BOM.

(you can check that in Notepad++, Encoding menu)
