I saw some file generation codes which uses the pack function.
echo pack("ssssss", 0x809, 0x8, 0x0, 0x10, 0x0, 0x0);
What this is doing exactly?
s signed short (always 16 bit, machine byte order)
I dont know why i am not able to understand this in realtime. Am not asking a theoretical answer
When i execute the php , file got generated with some stange characters which is not identified by ms excel.
I just want to know the use of pack(), where to use and how to use?
