pipelining and zScore of unexisting element bug

[adammada]

Hi,

i have code in which i want to determine if n elements are in Sorted Set.

I can do:

$pipeline = $redis->multi( Redis::PIPELINE );
foreach( $target_keys as $id )
{
$pipeline->zRank( 'set' , $id );
}
$ret = $pipeline->exec();

and then check if false was returned. But i prefer to make:

$pipeline = $redis->multi( Redis::PIPELINE );
foreach( $target_keys as $id )
{
$pipeline->zScore( 'set' , $id );
}
$ret = $pipeline->exec();

cause zScore is faster than zRank. But it doesnt work, cause if element doesn't exists, $ret table dosent have any information. (no false, just no entry).

Hello,

I have added a unit test for your case and have found no issue. If you look at the changes in commit 00b5784 and print the contents of $ret after the call to exec(), you will see the last entry is false, as expected.
