php二维数组去重

方法一：降维去重

        if (!$isPidArrKey) {
            //降维去重
            $temp = array();
            foreach ($tmp as $k => $v) {
                $v      = implode(&#39;,&#39;, $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[&#39;cid&#39;] == $k) {
                        // $value[&#39;cid&#39;] = 24;
                        $comBusInfo = $com->getMore(array($value[&#39;cid&#39;]));
                        if (!empty($comBusInfo)) {
                            $value[&#39;qq&#39;] = $comBusInfo[0][&#39;contactArr&#39;][&#39;qq&#39;];
                        }
                        if (in_array($value[&#39;pid&#39;], $idsTmp)) {
                            continue;
                        }
                        $idsTmp[] = $value[&#39;pid&#39;];
                        if ($isPidArrKey) {
                            $tmp[$key] = array_merge($value, $v);
                        } else {
                            $tmp[] = array_merge($value, $v);
                        }
                    }
                }
            }
