http://php.net/manual/en/wrappers.php.php
per the documentation: php://memory and php://temp are both listed
under "Allows Appending"
what am I missing / what's the point?
They only seem to work with read/write modes such as
fopen('php://memory','rw');
closing the handle, or trying to open another handle without closing
the first essentially erase the contents... so what's the point of
fopen('php://memory','a') ?
you'll
a) be appending nothing,
b) no way to read what you just wrote?
sure would be nice if you could
$fh = fopen('php://memory', 'w');
fwrite($fh, 'test string');
fclose($fh);
$fh = fopen('php://memory', 'r');
$result = fgets($fh,2048);
fclose($fh);
echo $result;

These are temporary "files" - as soon as they are closed, they go away,
as you note. So it really doesn't make any sense to open them other
than for read/write.
Other options are there - but those are just standard options for any
file. It doesn't mean you need to use them.
