1. $ _ GET is used to obtain data in the form of get in the table method.

2. $ _ GET url. php? I = 12 data,

The above is the data we often use get to obtain values,

Instance 1: Get form data

The instance code is as follows:

1.  

Get. php

If I fill in a http://www.phpfensi.com

The instance code is as follows:

1. You are .

The output result is

The instance code is as follows:

1. You are http://www.phpfensi.com

What is the url style when we click to submit?

The instance code is as follows:

1. Get. php? Username = www.phpfensi.com

This form is the second method we are talking about to obtain data. next we will look at using a for reference.

/A. php? Value = my

A. php

The instance code is as follows:

1. The value of value is .  

The output result is

The instance code is as follows:

1. The value of value is my.

This seems to be no different from form's method = get. haha, the article is here.

There is another way to get, that is, the form of direct $ _ GET, and view the instance.

The instance code is as follows:

2. Apple  
3. Orange  
4. Mango  

Checkbox. php file code

The instance code is as follows:

1. ";
2. Foreach ($ _ GET ["fruit"] as $ value)
3. {Echo $ value ," ";
4. }?>

The output result is

If you choose Orange and Mango

Note that $ _ GET is not suitable for obtaining a large amount of data. the length value cannot exceed 100 characters.
