我如何将这个数组划分为块？

Question

我想将数组划分为特定的块

喜欢

array1 = 24%;
     array2 = 50%;
     array3 = 26%;

$myArray = array("abc","def","ghi","jkl","mno","pqr","stu","vwx","yz");
$newArray = array_chunk($myArray, 3, false);

数组可能包含数十亿条记录。

Answer 1

$cnt=count($myArray);
$cnt1=round($cnt*0.24);
$cnt2=round($cnt*0.5);

//使用array_slice $ here

array(
    array_slice($array,0,$cnt1);
    array_slice($array,$cnt1,$cnt2);
    array_slice($array,$cnt1+$cnt2);
);

Answer 2

尝试查看array_slice()。
