PHP9 the use of a Super global variable (II.)

Today, $_get () and $_post ().

In fact, it is easy to understand, according to the superficial meaning can be seen, is to obtain the post and get form data, in fact, it is so, to point professional words,

The $_get variable is an array of variable names and values that are sent by the HTTP get method.

The $_get variable is used to collect values from the form method= "get". The information sent from a form with a Get method is visible to anyone (it appears in the browser's address bar) and has a limit on the amount of messages sent (up to 100 characters). OK, for example, the code for the simple login interface:

 
 

  
   
    
    Login Name: 
    Password: 
     
     
     
    
  

 
 

It will be submitted to get.php this page, and then look at its code:

Welcome 
 
  .

Password is 
 
 

You can take the value of the table Tan Riming to name by $_get[' name '. The effect is as follows. $_get () effect.

$_post and $_get () are essentially no different, just the difference between get fish POST, where I don't dwell on, code and get, the index page just changes method to POST, accept page to $_post[' name '].$_ Post effect.
