When switch on BINARY_PROTOCOL we see strange things while using values got from getMulti method.
Look at the end of the output - we get NULL instead off the "value0".
If the BINARY_PROTOCOL is turned off everything works fine.

array(2) { ["key_0"]=> string(6) "value0" ["key_0_additional"]=> string(17) "value0_additional" }
string(6) "value0"
array(2) { ["key_0_additional"]=> string(17) "value0_additional" ["key_0"]=> string(6) "value0" }

Reproduce code:
$cache = new Memcached();
$cache->setOption(Memcached::OPT_BINARY_PROTOCOL, true);
$cache->addServers( array( array('localhost', 11211) ) );
$cache->set( 'key_0', 'value0' );
$cache->set( 'key_0_additional', 'value0_additional' );
// -------------- NORMAL
$keys = array( 'key_0', 'key_0_additional' );
$values = $cache->getMulti( $keys );
echo "Values:<br>\n"; var_dump( $values ); 
echo "<br>\n";
echo "key_0:<br>\n"; var_dump( $values['key_0'] );
echo "<br>\n";
// --------------- REVERSED KEY ORDER
$keys = array( 'key_0_additional', 'key_0' );
$values = $cache->getMulti( $keys );
echo "Values:<br>\n"; var_dump( $values );
echo "<br>\n";
echo "key_0:<br>\n"; var_dump( $values['key_0'] );
echo "<br>\n";

Expected result:
string(6) "value0"

Actual result:

I'm having strange issues with multiget and binary protocol as 
well. I'm trying to make a small testcase. The issue for me is 
that I get keys returned with other values than the ones asked 
for. If I ask for key "xmlprod677" I can get "xmlprod6772" 
returned instead.

I'm running PHP 5.3.0 on snow leopard with the latest version 
of the extension from github (5d01619) and libmemcached 0.3.5.

It looks like I get different result from array_diff() and 
array_diff_key(). Could this be a PHP problem or am I missing 

Example code:

Forgot my result from my example code:
xmlprod677 and an empty array.

The returned value is null, which means there might be an error. Could you post what getResultMessage() and getResultCode() return?

The problem was that keys are not 0-terminated by libmemcached when using the binary protocol. Fixed that, and you may pull my fix from github (6abbe4b9f, devel branch)

This seems to be a duplicate of Bug #16829, sounds like you're having the same trouble I am.

The null termination patch seems to have taken care of my 
problems. Thanks!
