Bug description:32bit signed littleendian (machine independent) support for
pack() and unpack()
Description:
------------
pack() and unpack() are very useful functions, but would be nice to have a
machine
independent support for signed numbers, especially signed 32-bit little
endian. If
there are code alread for this, then they only missing from the
documentation.
Test script:
---------------
// Let's say, "E" would mean 32-bit signed little endian
echo unpack("E","A\xE2\x82\xAC")[1]."\n"; //PHP 5.4 syntax, would give back
always -1400708543, regardless of architecture endianness (same az "l" on
little endian system).
echo pack("E",-1400708543)."\n"; //would give back A⬠on a UTF-8
terminal, same as "l" on a little endian system
Expected result:
----------------
-1400708543
Aâ¬
Actual result:
--------------
unknown format code
