PHP数组的截取，等分以及替换部分数组在本篇中将介绍数组的截取（array_slice），等分（array_chunk）和替换（array_splice）以及 array_slice和array_splice的区别！在前面的三篇文章《如何对PHP数组进行排序?》《PHP数组随机乱序和反序》以及《PHP数组的倒序排列》中，我们分别介绍了数组的排序，其中包括数组的升序，降序以及乱序和反序，相信大家对数组的排序有一定了解了，今天我们来介绍另外的一组数组函数！什么是截取数组?(array_slice)array_slice从数组中取出一段元素，第一个参数是原数组，第二个参数是开始下标（牢记数组是从0开始的），第三个参数是从下标开始取出的元素个数，如果不设置，默认一直取到数组末尾！array_slice语法格式如下：array array_slice ( array&a
