問(wèn)題描述

$data = array( ['subject'=>'低段語(yǔ)文','one_name'=>'寫作卷','two_name'=>'古詩(shī)詞第1首','title'=>'11111'], ['subject'=>'低段語(yǔ)文','one_name'=>'寫作卷','two_name'=>'古詩(shī)詞第1首','title'=>'22222'], ['subject'=>'低段語(yǔ)文','one_name'=>'測(cè)試卷','two_name'=>'古詩(shī)詞第2首','title'=>'666666'], ['subject'=>'低段數(shù)學(xué)','one_name'=>'練習(xí)卷','two_name'=>'低段數(shù)學(xué)1','title'=>'333333'], ['subject'=>'低段數(shù)學(xué)','one_name'=>'練習(xí)卷','two_name'=>'低段數(shù)學(xué)2','title'=>'444444'], ['subject'=>'低段數(shù)學(xué)','one_name'=>'評(píng)估卷','two_name'=>'低段數(shù)學(xué)1','title'=>'777777'], ['subject'=>'高段語(yǔ)文','one_name'=>'繪畫卷','two_name'=>'繪畫1','title'=>'555555'], );

想先按subject封裝 然后底下是one_name 在是two_name 弄成一層層封裝的那樣。

問(wèn)題解答

$newArr = [];foreach ($data as $v){ foreach ($v as $kk=>$vv){$newArr[$kk][]=$vv; }}

這種?

代碼整理一下, 再發(fā), 沒格式,看起來(lái)太費(fèi)勁了
