client version is higher than daemon version (client is v.1.29 daemon is v.1.22)

安装好coreseek，建了索引，启动了服务，用php建了一个test.php，用于测试；<?phpinclude_once('sphinxapi.php');//向搜索引擎发起请求

$cl = new SphinxClient ();
$cl->SetServer ( '10.10.10.10', 9312);
//$cl->getLastError();
//$cl -> getLastWarning();
print_r($cl);
$cl->SetConnectTimeout ( 3 );
$cl->SetArrayResult ( true );
$cl->SetMatchMode ( SPH_MATCH_ANY);
$cl->SetSortMode ( SPH_SORT_ATTR_ASC,'rank' ); //以排名rank升序排列
$cl->SetLimits(0,2);
$query_data  = $cl->Query ( '小米', "*" );
?>

在A台机器执行的结果如下

在B台机器执行的结果如下：

SphinxClient Object

    [error] =>
    [warning] =>
)

通过PHP的调试信息，根本没有发现任何错误输出；请教了一个大神，他用 strace -s 1000 -f -o test.log php test.php ,分析 test.log ，发现了如下的错误

google了一番，通过在A，B 两台执行php --ini ,php -m 发现A机器中有php的sphinx扩展，而B机器中没有，终于找到具体的原因了。将A机器中的sphinx扩展去掉，重启php-fpm，就ok 了。

service php-fpm restart
