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

简介：PHP数组的类型-数字索引数组什么是PHP数字索引数组？这是最常见的数组类型，绝大多数编程语言都有数字索引数组PHP 数字索引数组一般表示数组元素在数组中的位置，它由数字组成，下标从 0 开始，数字索引数组默认索引值就是从数字 0 开始的，不需要特别指定，PHP 会自动为索引数组的键名赋一个整数值，然后从这个值开始自动增量，当然，也可以指定从某个位置开始保存数据。数组可以构造成一系列的“键-值（k...
简介：php怎么声明数组？在 PHP 中声明数组的方式主要有两种：一种是应用 array() 函数声明数组，另一种是直接通过为数组元素赋值的方式来声明数组。（什么是PHP数组?）其中，应用 array() 函数声明数组的方式如下：array array([mixed ...])参数 mixed 的语法为 key=>value，多个参数 mixed 之间使用逗号分开，分别定义索引...
简介：PHP数组的倒序在一篇文章《如何对PHP数组进行排序》中我们介绍了sort、asort和ksort，它们都是按照升序来对数组进行排序的，那么如果要实现数组的倒序呢？下面就是我们要说的另一组函数：rsort、arsort、krsort下面我们将一一介绍这组函数！rsortrsort —对数值数组进行降序排序。rsort() 函数对数组的元素按照键值进行逆向排序。与 arsort() 的功能...
Introduction: Reverse order of PHP arrays In an article "How to Sort PHP Arrays" we introduced sort, asort and ksort. They all sort arrays in ascending order. So if you want to implement What about the reverse order of the array? Here is another set of functions we are going to talk about: rsort, arsort, krsort. Below we will introduce this set of functions one by one! rsortrsort —Sorts a numeric array in descending order. The rsort() function sorts the elements of an array in reverse order by key value. With the function of arsort()...

Introduction: Our last article talked about "How to delete the head, tail, and any element in a PHP array". In this article we talk about deleting it through the array_unique() function Duplicate elements in the array. The array_unique() function sorts the values of the array elements as strings, and then only retains the first key name for each value and ignores all subsequent key names, which is to delete duplicate elements in the array. The syntax format is as follows: array arry_unique (array array) The parameter array is the input array...
