PHP Entry Form creation and basic processing _php tutorial

In order to facilitate the learning of arrays, the introduction of the transition chapter is the form, as for why, and so on when you really learn the array when you will find its beauty pull.

===================================================================

Form: A form is a region that contains form elements.

Form elements are elements that allow users to enter information in a table consignments (such as a text field, drop-down list, radio box, check box, and so on).

Forms use Form labels (

In the case of PHP, the most important attribute of the form tag is the action, which specifies which page the form data will be sent to, and the null is the page that contains the form, which is the current page;
The second property is method, which specifies how the data is sent to the processing page, and two options (get and Post) indicate the HTTP method to use.

Method Selection:

The Get method is to send the submitted data to the receiving page via a series of (name-value) pairs appended to the URL. For example:
Http://www.example.com/script.php?name=Homer&gender=M&age=35

Unfortunately, the amount of data transmitted through get is limited, and it is not very secure (because the data is visible).

Generally, get is used to request information, such as a specific record in a database or a search result (search almost always uses get).

Use the Post method when you need to take an action, such as when updating a database record or sending an e-mail message.

For these reasons, I generally use post, and if there are exceptions, I will say otherwise.

Now let's create a simple form, because this file does not contain PHP code, so my file is saved as (. html) suffix, of course, you can also use the (. php) suffix.
