Array form submission, array form submission
I encountered a problem today. I had to save a lot of form information. After worrying about it for a long time, I finally found a pretty good way to use an array. Submit the data in the form to the background for saving.
In fact, it is very simple to implement, that is, there must be certain standards when naming the information to be submitted in the form. Let us first compare the differences between the following two methods:
The first, common way, each value to be submitted has a name
<form id="form1" action="./index.php" method="get"> <div class="form-control"> <input type="text" name="name1" /> <input type="text" name="num1" /> <input type="text" name="img1" /> </div> <br> <div class="form-control"> <input type="text" name="name2" /> <input type="text" name="num2" /> <input type="text" name="img2" /> </div> <br> <div class="form-control"> <input type="text" name="name3" /> <input type="text" name="num3" /> <input type="text" name="img3" /> </div> ...... <input type="submit" value="Submit" /> </form>
The service (index.php) is as simple as two sentences
<?php echo "<pre class="brush:php;toolbar:false">"; print_r($_GET);
Fill in the following information on the rendered webpage and click submit
If you look carefully, you will find that the name of the data to be submitted has changed. It may not be obvious here. When you click submit, you will find that the values passed to the backend are much neater. Take a look at the screenshot below

php求2个数组相同元素的方法:1、创建一个php示例文件;2、定义两个有相同元素的数组;3、使用“array_intersect($array1,$array2)”或“array_intersect_assoc()”方法获取两个数组相同元素即可。

C语言数组初始化的三种方式:1、在定义时直接赋值,语法“数据类型 arrayName[index] = {值};”;2、利用for循环初始化,语法“for (int i=0;i<3;i++) {arr[i] = i;}”;3、使用memset()函数初始化,语法“memset(arr, 0, sizeof(int) * 3)”。

Part1聊聊Python序列类型的本质在本博客中,我们来聊聊探讨Python的各种“序列”类,内置的三大常用数据结构——列表类(list)、元组类(tuple)和字符串类(str)的本质。不知道你发现没有,这些类都有一个很明显的共性,都可以用来保存多个数据元素,最主要的功能是:每个类都支持下标(索引)访问该序列的元素,比如使用语法Seq[i]。其实上面每个类都是使用数组这种简单的数据结构表示。但是熟悉Python的读者可能知道这3种数据结构又有一些不同:比如元组和字符串是不能修改的,列表可以

c++初始化数组的方法:1、先定义数组再给数组赋值,语法“数据类型 数组名[length];数组名[下标]=值;”;2、定义数组时初始化数组,语法“数据类型 数组名[length]=[值列表]”。

增加元素的方法:1、使用unshift()函数在数组开头插入元素;2、使用push()函数在数组末尾插入元素;3、使用concat()函数在数组末尾插入元素;4、使用splice()函数根据数组下标,在任意位置添加元素。

php判断数组里面是否存在某元素的方法:1、通过“in_array”函数在数组中搜索给定的值;2、使用“array_key_exists()”函数判断某个数组中是否存在指定的key;3、使用“array_search()”在数组中查找一个键值。

php去除第一个数组元素的方法:1、新建一个php文件,并创建一个数组;2、使用“array_shift”方法删除数组首个元素;3、通过“print_”r输出数组即可。

在Go语言中,数组是一种重要的数据类型。它与其他语言的数组一样,是一组相同类型的数据组成,可以通过一个索引来访问数组中的元素。在某些情况下,我们需要从一个数组中删除元素,本文将会介绍在Go语言中如何实现数组删除。
