These social networks share several attributes in common:
Membership.
Social nets all generally requires user to register namesand accounts for avoid duplicate and secrecy so many public networks offer free registration, but some charge fees for their premium services. Private networks (such as BANK ACCOUNT HOLDERS groups) restrict registration to people who meet certain eligibility criteria.
Content contribution.
These networks allow members to easily share comments, movies, music, short films and/or photos with others.
Frequent return visits.
Healthy social net takes a centers around a base of members who check in regularly to contribute theirs and also for new updates.
Human relationship building.
The common goal of most social networks is allowing the interactions that build stronger connections with in communities of people

Encryption technology is an effective information security protection. It is defined as converting a plaintext into meaningless ciphertext using encryption algorithm thus ensuring the confidentiality of the data. The encryption or decryption process use a key to encrypt or decrypt the data. At present two encryption technologies are widely used. They are symmetric key encryption system and an asymmetric key encryption system. Thre figure below shows the Data Encryption and Decryption process:

OSS projects are collaboration opportunities that improve skills and build connections in the field.
Domains that developers can contribute to the open source community include:
1. Communication tools.
2. Distributed revision control systems.
3. Bug trackers and task lists.
4. Testing and debugging tools.
(i) There are many open source softwares. So, we can select and use any software that suits our needs.
(ii) The complete options of the software can be used without any cost and restrictions.
(iii) We can share our ideas with the team. write the required code and share it with many.
(iv) As we can identify the programming techniques of group members, we can learn many ideas and make our program writing skills more efficient.
(v) The coding in open source software are being groomed by many enthusiastical members of the groups. So, if we report problems that we have in the program they are quickly mended by the group's effort.
(vi) As we can make changes to the open source software, we can add the most required features in the software.
(vii) Many open source software are very user friendly.
 

MySQL function in PHP:
In PHP Scripting language many functions are available for MySQL Database connectivity and executing SQL queries.
MySQLi is extension in PHP scripting language which gives access to the MYSQL database. MySQLi extension was introduced version 5.0.0,
The MySQLi extension contains the following important functions which are related to MySQL database connectivity and management.
i) Mysqli_connect() Function
ii) Mysqli_close() Function
iii) Mysqli_query() Function
(i) Database Connections:
Before accessing MySQL Database, connect to Database Server machine via PHP scripting language using Mysqli_connect() Function.
Syntax :
mysqli_connect("Server Name "User Name","Password"DB Name");
This function requires four parameters to connect to database server. Database Server name, Database username, password anda Database Name.
(ii) Managing Database Connections :
The below code describes managing database connection methods and features.

The mysqli_connect function uses these variables to connect Database server to PHP. If connection gets fail, output will be printed with MySQL error code. Otherwise connection is success.
(iii) Performing Queries :
The main goal of MySQL and PHP connectivity is to retrieve and manipulate the data from MYSQL database server. The SQL query statements help in PHP MySQL extension to achieve the objective of MYSQL and PHP connection. "mysqli_query" is a function, that helps to execute the SQL query statements in PHP scripting language.
Syntax:
mysqli_query("Connection Object","SQL Query")
Example:

Closing Connection :
mysqli_close() Function is used to close an existing opened database connection between PHP scripting and MySQL Database Server.

'for loop' is called as the entry-check loop.
The for loop is used to execute a block of code a specific number of times.
Syntax:
for (initialization; condition; increment / decrement) 
{
          //code to be executed;
}
The initialization part is executed only once at the beginning of the loop. It is used to initialize variables. The condition is evaluated before each iteration of the loop. If it is true, the code block is executed. If it is false, the loop is terminated. The increment/ decrement part is executed after each iteration of the loop. It is used to update variables.
Example 1
To print the numbers from 1 to 5 in ascending order
for (i = 1; i<=5; i++)
{
          echo i. "<br>";
}
Output:
1
2
3
4
5
Example 2
To print the numbers from 5 to 1 in descending order
for (i = 5; i<=1; i--)
{
          echo i. "<br>";
}
Output:
5
4
3
2

Function in PHP:
A block of segment in a program that performs a specific operation such as Insert, Execute, Delete, Calculate etc.
A function is a type of sub-routine or procedure in a program.
The function can be divided into three types as follows.
(i) User defined Function
(ii) Pre-defined or System defined or Built-in Function
(iii) Parameterized Function
(i) User defined Function
PHP gives a privilege to user to write own specific operation inside of existing program module.
Two important steps the programmer has to create for users defined functions are
(a) Function Declaration
(b) Function Calling
(a) Function Declaration
A user defined function declaration begins with the keyword "Function".
User can write any custom logic inside in function block.
Syntax:
function functionName()
{
custom logic code to be executed;
}
(b) Function Calling
A function declaration part will be executed by a call to the function.
Programmer has to create function calling part inside the respective program.
Syntax:
functionName();
(ii) Pre-defined or System defined or built-in Function
Built-in functions are functions that exist in PHP installation package.
Functions can either return values when called or can simply perform an operation without returning any value.
Example:
rename_function()
This function renames original name to new name.
Parameter is also called as arguments just like variables.
Arguments are mentioned after the function name and inside the parenthesis.
There is no limit for sending arguments, just separate them with a comma notation.
Examples :
Parameterized function with one argument, two arguments respectively.
(i) function School Name ($sname)
(ii) function School Name ($sname, $strength)

(iii) Click on File > Place. The Place dialog box will appears.
(iv) Locate the document that contains the text you want to place, select it.
(v) Click on Open.
(vi) Click in a frame to place the text in it.The text will be placed in the frame.

(i) Immediate money transfers through mobile device round the clock 24 x 7.
(ii) Can use single mobile application for accessing multiple bank accounts
