hye guys, i have a .txt file which contain hex value such as F5/01/00/01/00/03/00/F5 (03 nad 01 appear as boxes in text file), and i wanted to take this value into php and convert it into binary. is it possible?
Is the string actually the hex string? e.g."F5010001000300F5" ?
My first question, is why store it in this format? Store the binary and safe a lot of work/effort?
it actually an output from a device,i just transfer it to a file.
Have you tried:
$binary = hex2bin(file_get_contents('file.txt));
$binary = pack('H*' , file_get_contents('file.txt));
tried already..but still can't..i use this code below
$contents = file_get_contents('output.txt');
and the output is õõõõõõõõõõõõ. thats F5F5F5F5F5F5F5 in ISO-8859-1 format..why is that?
Can you paste the exact contents of output.txt or at least the first few hundred bytes.
