Bug description:fseek() on memory stream behavior different then file
Description:
------------
May not be a bug but a documentation issue
With a file, fseek() to an offset that doesn't exist results in NULL bytes
added.
Using a memory stream, fseek() just fails.
Which one is the expected behavior? Also for streamWrapper::stream_seek()
Test script:
---------------
$sp = fopen("php://memory", 'w+');
fseek($sp, 1024); // fails why?
echo fwrite($sp, "abc"); // 3
fseek($sp, 1024); //
echo fread($sp, 3); // NULL..
$sp = fopen("/tmp/foo", 'w+');
fseek($sp, 1024);
echo fwrite($sp, "abc"); // 3
fseek($sp, 1024);
echo fread($sp, 3); // abc
Expected result:
----------------
3abc3abc
Actual result:
--------------
33abc
