Protection must be done everywhere the method is called, and escaping in the method reflects the meaning of defense in depth.What happens if a user attempts to enter a very long value, such as up to 1000 characters, to attempt to initiate a buffer overflow attack? The next section discusses this in more detail, but you can now add another check to make sure the PID you entered has the correct length. You know that the maximum length of the PID field for a database is 5 bits, so you can add the

Reason to find a long time! The subclass object has been assumed to be unable to be assigned to a parent class reference. It's not science!
The code is like this:
.
Simply introduce
var a = new object ();//Create an object with no parent
var B = object.create (a.prototype);//b inherits the prototype of a.
Inherited

. Create a database
Creating a DatabaseThe CREATE DATABASE statement is used for creating databases in MySQL.
GrammarCREATE DATABASE database_name In order for PHP to execute the above statement, we must use the mysql_query () function. This function is used to send a query or command to a MySQL connection.
ExampleIn the following example, we created a database called "my_db":
code is as follows
copy code
$con = mysql_connect ("localhost", "Peter", "abc123"
by implementations are used when there are available indexes, and when the MySQL Query Optimizer cannot find the right index to exploit, it has to read the required data first and then complete the GROUP by operation through a temporary table.
code is as follows
