![]() 76 characters is enough for 19 quadruples of six-bit symbols thus representing 19 triples of eight-bit symbols. MIME additionally enforces a line length of 76 characters plus the CRLF. Reading the input file in chunks that are a multiple of three bytes in length results in a chunk that can be encoded independently of the rest of the input file. fputs($fh2, base64_decode($put)) // for comparingīase64 encoding converts triples of eight-bit symbols into quadruples of six-bit symbols. ![]() Here comes the corrected version which I have tested for all kind of files and length (up to 4,5 Gb!) without any error: The error was caused by the use of "empty()". But lower values then 1024 are bad overall because they slow down the whole process, so 4096 will be fine for all purposes, I guess. The first led to an endless loop because of a missing "$feof"-check, the second caused the rare mentioned errors when encoding failed for some reason in larger files, especially when Unfortunately my "function" for encoding base64 on-the-fly from 2007 had 2 errors!
