选择多个数组元素 [英] Selecting multiple array elements

问题描述

PHP中是否有一种方法可以一次选择多个数组元素，例如这样，在for循环中，$ i =要选择的第一个集合的大小，然后后续递增表示从数组-?

Is there a way in PHP to select multiple array elements at once, e.g. such that in a for loop, $i = size of first set to be selected, and then subsequent increments represent selecting the next set of that size, from an array - ?

谢谢！

推荐答案

即而不是一次循环遍历一个数组元素，而是循环遍历选定的对(例如3个元素，然后对这3个元素做些事情).

I.e. instead of just looping through one array element at a time, but to loop through selected pairs instead (e.g. 3 elements, and then to do something to those 3).

有很多方法可以实现.
一个会是

there are many ways to do it.
one would be

$arr = array(1,2,3,4,5,6,7,8,9);
$new = array_chunk($arr,3);
foreach ($new as $chunk) {
  print_r($chunk);// 3 elements to do something with
}
