I am trying to parse a csv file using fgetcsv() function but the CSV file's heading consists value like E-mail Address' which I need to convert as an array's key but I am wondering if it's OK to use a non-standard name for a key?
I would be saving this value in database directly so I am not sure if getting a value like this $entry['E-mail Address'] would be ok
A string is a string. The fact that it has a whitespace in the middle shouldn't prevent you from using it as an array's key.
