Expected behaviour

SCRIPT EXISTS will return an array with TRUE or FALSE for each passed script

Actual behaviour

return false

I'm seeing this behaviour on

• OS: Centos 6.5
• Redis: 3.0.7
• PHP: 5.6.1
• phpredis: 3.1.3

Steps to reproduce, backtrace or example script

connect redis cluster...

$keys = ['test'];
$args = [100];
$sha1 = "727c0136efce8e1e7b34a5d1a29c87b77a9348ff";
$script = "local count = redis.call('incr',KEYS[1]); if tonumber(count) == 1 then
redis.call('expire',KEYS[1],ARGV[1]); end; return count;";

// 检测脚本是否存在服务端
$scriptExists = $redisObj->script('exists', $sha1);
if(!$scriptExists || !$scriptExists[0]) {
// load脚本
$serverSha1 = $redisObj->script('load', $script);
if($serverSha1 !== $sha1) {
throw new Exception($scriptKey.'脚本的sha1与服务端返回的sha1不一致'.$sha1.'=='.$serverSha1, 999);
}
}
$keyCount = count($keys);
// 不需要键名索引，用数字重新建立索引
$args = array_values(array_merge($keys, $args));
$result = $redisObj->evalSha($sha1, $args, $keyCount);
