Re: problems / mistake in pack () and unpack() ???

if you wrote to the file from say a PowerPC (big endian) (eg MacOSX) using I or L, then read the file using a Intel (or AMD) (little endian) (eg Windows) using I or L, then it would give different results. -- Louis Solomon www.SteelBytes.com "Burkhard Herre" <bherre@telematica.de> wrote in message news:428B60C3.20706@telematica.de... > hello > > i use the function pack() and unpack() > > i have following question: > > > $content = -2147483647; > $binarydata = pack("V", $content); > > ...(fwrite in file) > ...(fread from file) > > $bin_str = fread ($handle, 4); > $ascii_array = unpack("V", $bin_str); > $ascii_str = $ascii_array[1]; > > it makes no difference if i use the "V", the "l" or the "L" flag ! > > every flag works the same...output is '-2147483647' > > but from the php page i get this: > > l -- Long-Typ with sign (always 32 Bit, Byte-sequenz maschine depent) > > L -- Long-Typ without sign (always 32 Bit, Byte-sequenz maschine depent) > > V -- Long-Typ without sign (always 32 Bit, little endian) > > > why is it so ? > what happends ? > > > > thank you > > > > > > >
