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; }
方法二:借助第三个数组去重
$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); } } } }
