A brief introduction to PHP submitting Form form

This article mainly introduces the introduction of PHP form 2 methods and simple examples, very practical, the need for small partners can refer to.

Handling GET Requests

The implementation of the function is to enter the name after the page display "Hello XXX"

To create an HTML file hello.html:

?

1 2 3 4 5 6 7 8 9 10 11 12-13

<! DOCTYPE html>

Create PHP file hello.php:

?

1 2 3 4 5 6 7 8 9 10 11 12-13

<?php/** * Created by Phpstorm. * User:administrator * DATE:2015/6/30 * time:15:03/Header ("content-type:text/html; Charset=utf-8 "); if (isset ($_get[' name ')) &&$_get[' name '] {//If there is a value and is not empty echo ' Hello '. $_get[' name ';} else{echo ' please input name ';}

The GET request places the form's data explicitly in the URI and limits the length and data value encoding, such as: Http://127.0.0.1/hello.php?name=Vito

Process POST Requests

Implementation of a simple addition operation function

To create an HTML file add.html:

?

1 2 3 4, 5 6 7 8 9 10 11 12 13 14 15

<! DOCTYPE html>

Create PHP file add.php:

?

1 2 3 4 5 6 7 8 9 10 11 12 13-14

<?php/** * Created by Phpstorm. * User:administrator * DATE:2015/6/30 * time:18:02/if ($_post[' num1 ']&&$_post[' num2 ']) {echo $_post[' NUM1 ']+$_post[' num2 ']; }else{echo ' please input num ';}

Post requests place form data in the HTTP request body with no length limit

Form action= "" means: Form is the forms, action is to address, that form form needs to be submitted to where
