php two-dimensional array deduplication

Method 1: Dimensionality reduction and deduplication

        if (!$isPidArrKey) {
            //降维去重
            $temp = array();
            foreach ($tmp as $k => $v) {
                $v      = implode(',', $v);
                $temp[] = $v;
            }
            $temp = array_unique($temp);
            foreach ($temp as $k => $v) {
                $temp[$k] = explode(",", $v);
            }
            $tmp = $temp;
        }

Method 2: Use the third array to remove duplicates

$idsTmp = array();
            $com    = new CacheCombusiness();
            foreach ($proInfo as $key => $value) {
                foreach ($comInfo as $k => $v) {
                    if ($value['cid'] == $k) {
                        // $value['cid'] = 24;
                        $comBusInfo = $com->getMore(array($value['cid']));
                        if (!empty($comBusInfo)) {
                            $value['qq'] = $comBusInfo[0]['contactArr']['qq'];
                        }
                        if (in_array($value['pid'], $idsTmp)) {
                            continue;
                        }
                        $idsTmp[] = $value['pid'];
                        if ($isPidArrKey) {
                            $tmp[$key] = array_merge($value, $v);
                        } else {
                            $tmp[] = array_merge($value, $v);
                        }
                    }
                }
            }
