PHP $_GET gets HTML form (Form) or url data_PHP tutorial

Today I have nothing to do and I will tell you how to use get global variables when I learned PHP more than a year ago. Friends who need to get started can refer to it.

1. $_GET is to obtain the data in the form of get table method
2. $_GET gets the data of url.php?i=12,
The above is the data we commonly use get to obtain values,

Example 1, obtaining form data

The code is as follows

Copy code

代码如下	复制代码
Name:

Name:

代码如下	复制代码
You are .

get.php

If I fill in www.hzhuti.com

The code is as follows

Copy code

代码如下	复制代码
You are www.hzhuti.com

You are .

代码如下	复制代码
get.php?username=www.hzhuti.com

The output result is

The code is as follows	Copy code
You are www.hzhuti.com

So what will the URL look like when we click submit

The code is as follows

Copy code

get.php?username=www.hzhuti.com

代码如下	复制代码
value的值是 .

This is the form, which is the second method of obtaining data. Let’s look at using a with reference

代码如下	复制代码
value的值是 my

/a.php?value=my a.php

The code is as follows	Copy code
The value of value is .

The output result is

The code is as follows	Copy code
The value of value is my

This looks no different from method=get of form, haha, that’s it for the article.

There is another way to get, which is to directly $_GET. What form will it take? See the example.

The code is as follows

代码如下	复制代码
Apple Orange Mango

Copy code

代码如下	复制代码
"; foreach ($_GET["fruit"] as $value) {echo $value," "; }?>

Apple

Orange

Mango

checkbox.php file code

The code is as follows

Copy code

";

foreach ($_GET["fruit"] as $value)

{echo $value,"
"; }?> The output result is If you choose Orange and Mango Note that $_GET is not suitable for obtaining large amounts of data. The length value cannot exceed 100 characters.
