求教下数组输出的问题

Array(    [IsSuccesfull] => 1    [Results] => Array        (            [SingleResul] => Array                (                    [0] => Array                        (                            [QueryId] => 100093                            [PathId] => 1                            [SourceFolder] => 1111111                        )                    [1] => Array                        (                            [QueryId] => 100093                            [PathId] => 2                            [SourceFolder] => 1111                       )                )        ))

$ar=array();foreach($t['Results']['SingleResul'] as $v){        if(!isset($ar[$v['QueryId']])){                $ar[$v['QueryId']]=$v;        }}foreach($ar as $v)  echo join(' | ' , $v)."<br>";
