Does anyone have a solution to this problem?

Answer 1

Yes, It has been deprecated

You should convert the result of the calculation to an integer when passing to chr():

strtolower(
    (
        ($i-1)/26>=1
            ? chr((int) ($i-1)/26+64)
            : ''
    )
    . chr((int) ($i-1)%26+65)
)
