Hi,

I'm having gzip data coming back as data like this:

Code:
\x1f\x8b\x08\x00\x00\x00\x00\x00

Is this dec/bin/he/whatever?

How could I read this in, saying using PHP? fgets get stuck on this kind of data. Maybe I have to convert it to another type somehow? unpack maybe?

Thanks!

It's hexadecimal (base 16). the "x" is the giveaway. The thing is, in PHP, all you have to do is print it (with echo or print). However, in the example above, the only printable character is 0x8b, which is decimal 139, and that's high-ASCII, so the value depends on the font and encoding.

[php]

$var1 = "\x1f\x8b\x08\x00\x00\x00\x00\x00";

print $var1;
[/php]

In the sequence you have there though, you print chr(31), chr(139), chr(8), and a bunch of chr(0), which is null. If you look at an ASCII table, you'll see that chr(31) is a non-printing character, chr(8) is a backspace, and chr(139) is effectively erased by the backspace, however it would have been rendered.

For those who are interested, base 16 counts like this:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 1a, 1b, 1c, 1d, 1e, 1f, 20, 21 ...

Et cetera. Computer programmers use hexadecimal notation because you can count 8 bits (0 to 255) with two characters (00 to ff).

Thanks for the reply! How would I use gzlib functions in PHP to get the normal string?

Thanks!
