Understand with Example

The Tutorial helps you to illustrate an example from 'PHP SQL Injection Example'. To understand and grasp the example we create a table 'Stu' that has required fieldnames and datatypes respectively. The Table 'stu' has a Primary Key 'id'. 

Create Table Stu:

CREATE TABLE `stu` (                     
          `id` int(11) NOT NULL auto_increment,  
          `name` varbinary(10) default NULL,     
          `class` int(11) default '12',          
          PRIMARY KEY  (`id`)                    
        )

Insert.php:

The Insert.php include the html form page that allows the users to add the records in  table 'stu'. When a user click on  submit button in the HTML form, the data records sent to the table 'stu'.
