TABLE requests in PHP are simple.
The variable $ is added before the name specified by the name.
To receive an array, simply specify the name = "variable [0.
Furthermore, conversion of character codes is unnecessary.

When you run the code below test. php, the test process performs a table request.
Once the data is input Is the initial value of the table.

       
   Table request test      
Upload table request test Upload
        
 \ $ A = $
  
\ $ B [0] = $ B [0]
  
\ $ B [1] = $ B [1]
  
\ $ C = $ c
END_OF_HTML;} else {?>
Enter data.
  
         

Query request

Like QUERY_STRING, the query request is as simple as FORM.
Add the $ parameter before the specified query identification name.
What is the image obtained by means of permutation? Variable [0] =.

Use urlencode to filter out English numbers in QUERY_STRING.
$ Para1 = urlencode ($ para1 );

Run the following code of test. php to perform the test.

       
   Query request test      
Pipeline query request test pipeline
      
 \ $ A = $
  
\ $ B [0] = $ B [0]
  
\ $ B [1] = $ B [1]
END_OF_HTML;} else {?>
No data.
  
         

Terminal data Cookie

In PHP, writing and obtaining cookies is actually very simple.
There are also writing methods for Cookie writing as html meta, but here, setcookie is entered using PHP encoding.
In addition, setcookie and initial execution in HTML are necessary.

Cookie acquisition means that the Cookie is obtained by appending the $ variable before the Cookie name.
Because the cookie exists on the request header, and the setcookie is set by the variable immediately after it is requested, it is the value of the request.
The first round is of course empty.
If you have any questions, process $ cookiename,
$ Cookiename = 'data ';
Setcookie ('cookiename', $ cookiename, time () + 60 );
That's all.

The code below test3.php is used to run the test for Cookie. The Cookie expiration date is 60 seconds.

[Tracing]
Next time test3.php does not work.
Insert
$ Cookiename = $ _ COOKIE ["cookiename"];
It seems to work. (Thank you for your information)

       
   Cookie test      
Renew Cookie test
      
 \ $ Cookiename = $ cookiename
END_OF_HTML;} else {?>
No Cookie data.
  
When data is loaded again within 60 seconds, the written Cookie is read.
