Bug description:Inconsistent stream_select() behavior for php://memory vs.
php://temp
Description:
------------
Streams of type php://memory cannot be represented as selectable
descriptors
where stream_select() is concerned. Attempting to do so will (rightly)
trigger an
E_WARNING along the lines of "Warning: stream_select(): cannot represent a
stream
of type MEMORY as a select()able descriptor in ..."
I would expect streams of type php://temp to behave the same way. However,
this
is not the case. Instead, php://temp streams are immediately readable (but
do not
evaluate to TRUE for feof($stream). These streams should either (1) trigger
an
error similar to that of php://memory or (2) not be represented as readable
by
stream_select().
Test script:
---------------
$stream = fopen('php://memory', 'r+');
$r = array($stream);
$w = $e = NULL;
stream_select($r, $w, $e, 0); // E_WARNING (as expected)
$stream = fopen('php://temp', 'r');
$r = array($stream);
$w = $e = NULL;
if (stream_select($r, $w, $e, 0)) {
var_dump(feof($stream)); // this isn't readable and should never be
called but it results in bool(false)
}
Expected result:
----------------
The test script should trigger two warnings and neither stream should
report as
readable.
Actual result:
--------------
php://temp streams do not trigger an error when used with stream_select()
and are
immediately reported as readable.
