I wrote PHP code for image verification with a myanmar word but header already send error occur. I check the code and it’s OK. I make a new php file and just test again it.It’s also occur. So, I googling and I found the error it. I used UTF-8 file format. UTF-8 send header when run a php code. So, I change file format to ASCII and run again. Wow… it’s OK. So, I can’t write image verification with a myanmar word. Myanmar character use UTF-8 file format and its nightmare for me.
