下面這堆數(shù)組wid,gid全部相同的，要求Num累加，不同的不操作直接顯示，數(shù)組去重如何實(shí)現(xiàn)？Array([0]=>Array([id]=>1[no]=>WF20170001[wid]=>1[gid]=>1[num]=>4[price]=>2.55[amount]=>10.20[buyer]=>顧文君[invoice]=>123456789[date]=>2017-03-28[remarks]=>測(cè)試數(shù)據(jù)[cid]=>pc001[class]=>辦公用品[name]=>筆記本電腦[type]=>AcerAspireE1-410G[unit]=>臺(tái)[warehouse_name]=>辦公用品倉(cāng)庫(kù))[1]=>Array([id]=>3[no]=>WF20170001[wid]=>1[gid]=>5[num]=>5[price]=>100.00[amount]=>500.00[buyer]=>顧文君[invoice]=>1231241[date]=>2017-04-14[remarks]=>入庫(kù)測(cè)試[cid]=>tf001[class]=>辦公用品[name]=>打印機(jī)碳粉[type]=>88A[unit]=>支[warehouse_name]=>辦公用品倉(cāng)庫(kù))[2]=>Array([id]=>4[no]=>WF20170001[wid]=>1[gid]=>2[num]=>1[price]=>4500.00[amount]=>4500.00[buyer]=>張秀珍[invoice]=>4558895[date]=>2017-04-09[remarks]=>入庫(kù)測(cè)試[cid]=>pc002[class]=>辦公用品[name]=>筆記本電腦[type]=>AcerAspireE5-571G-58WT[unit]=>臺(tái)[warehouse_name]=>辦公用品倉(cāng)庫(kù))[3]=>Array([id]=>5[no]=>WF20170002[wid]=>1[gid]=>3[num]=>1[price]=>88.00[amount]=>88.00[buyer]=>顧文君[invoice]=>556789[date]=>2017-04-09[remarks]=>測(cè)試數(shù)據(jù)[cid]=>ow[class]=>辦公用品[name]=>萬(wàn)用表[type]=>萬(wàn)用表[unit]=>臺(tái)[warehouse_name]=>辦公用品倉(cāng)庫(kù))[4]=>Array([id]=>12[no]=>WF20170001[wid]=>1[gid]=>1[num]=>1[price]=>2.55[amount]=>2.55[buyer]=>顧文君[invoice]=>53412312[date]=>2017-06-05[remarks]=>無(wú)[cid]=>pc001[class]=>辦公用品[name]=>筆記本電腦[type]=>AcerAspireE1-410G[unit]=>臺(tái)[warehouse_name]=>辦公用品倉(cāng)庫(kù)))

$temp=[];foreach($dataas$item){//$data為待處理數(shù)據(jù)if(isset($temp[$item['wid']][$item['gid']])){$temp[$item['wid']][$item['gid']]['num']+=$item['num'];}else{$temp[$item['wid']][$item['gid']]=$item;}}$result=[];foreach($tempas$wid=>$val1){foreach($val1as$gid=>$val2){$result[]=$val2;}}var_dump($result);

我的理解其實(shí)你現(xiàn)在做的就是php層面實(shí)現(xiàn)mysqlgroupby//偽代碼思路$tmp_arr=[];foreach$tmp_arr[$v['wid'].$v['gid']]+=$v['num'];//自己判斷下數(shù)據(jù)件是否存在,不存在就初始化0,還要把重復(fù)的key刪除掉,加在第一個(gè)上面這個(gè)臨時(shí)數(shù)據(jù)判斷下下哪個(gè)key需要?jiǎng)h除
