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);

Copy after login

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

The query string parsed through the browser plug-in is like this
