php$tags = array(    Array(            'tagId' => 9677,            'tagName' => '羚羊感冒片',            'tagType' => 2,        )    , Array        (            'tagId' => 9678,            'tagName' => '羚羊感冒片',            'tagType' => 2        )   );  assoc_unique($tags,'tagName','tagType');  print_r($tags);function assoc_unique(&$arr, $key,$key2) {         $res=array();        for($i=0;$i

把tagName和tagType联合起来，当做一个新数组的key不就得了

楼上说的方法最简单啦！把tagName和tagType链接起来作为新数组的key，自动过滤掉了重复值
