2. Venues and local shops can advertise upcoming events on social networks.
3. Businesses able market their products to customers (and retrieve some direct feedback).

3. Fostering diversity of thought:

1. Some critics of social networks point out that online communities attract people by similar interests and backgrounds.
2. Indeed, when the people with different opinions do get together on online, many discussions seem to degenerate into personal attacks and so-called “flame wars.”
3. It can be argued, by online debates are healthy in the long run.
4. Although individuals may begin with more extreme views, over time their thinking gets influenced may begin with more extreme views, over time their thinking gets influenced by the comments of others at least to some extent.
5. For people who stuck with a busy schedule can have some relaxation and known current affairs, news via these social networks can easier to wish someone and keep in touch their follower, loveable person.

Question 3.
Explain in details types of MySQL connection method in PHP.
Answer:
Open a Connection to MySQL
There are several methods for connecting to a MySQL database using PHP:

• MySQL Improved (mysqli) extension
• PDO (PHP Data Objects)
• Legacy MySQL (mysql_) functions
• Connecting to a remote MySQL database using PHP

Connecting to MySQL using the MySQL Improved extension
The MySQL Improved extension uses the mysqli class, which replaces the set of legacy MySQL functions.

Connecting to MySQL using PDO (PHP Data Objects)

• The MySQL Improved extension can only be used with MySQL databases.
• PDO, on the other hand, abstracts database access and enables you to create code that can handle different types of databases.

Connecting to MySQL using the legacy MySQL functions

• The original PHP MySQL functions (whose names begin with mysql_) are deprecated in PHP 5.5, and will eventually be removed from PHP.
• Therefore, you should only use these functions when absolutely necessary for backward compatibility.
• If possible, use the MySQL Improved extension or PDO instead.

Connecting to a remote MySQL database using PHP

• The previous examples all assume that the PHP script runs on the same server where the MySQL database is located.
• But what if you want to use PHP to connect to a MySQL database from a remote location.
• For example, you may want to connect to your A2 Hosting database from a home computer or from another web server.

Question 4.
Explain MySQLi Queries with examples.
Answer:
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 are helping with PHP MySQL extension ^to achieve the objective of MySQL and PHP connection. “mysqli_query” is a function, helps to execute the SQL query statements in PHP scripting language.

Syntax:
mysqli_query(“Connection Object” “SQL Query”)
Example:
$con=mysqli_connect(“localhost”,“my_user”,“my_password”,“Student_DB”); $sql=“SELECT student_name,student_age FROM student”;mysqli_query($con,$sql);

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

Syntax:
mysqli_close(“Connection Object”);
<?php
$con=mysqli_connect(“localhost”,“$user”,“$password”,“SCHOOLDB”);
// ….some PHP code… mysqli_close($con);
?>

Example of PHP and MySQL Program:
<?php .
$servemame = “localhost”;
$usemame = “username”;
$password = “password”;
$dbname = “schoolDB”;
$connection = mysqli_connect(“$servemame”, “$usemame”, “$password” “$dbname”);
if (mysqli_connect_error ( ))
{
echo “Failed to connect to MySQL:”
mysqli_connect_error( );
}
sql stmt = “SELECT * FROM mycontacts”; //SQL select query
$result = mysqli_query($connection,$sql_stmt);//execute SQL statement$rows =
mysqli__num_r°ws($result);// get number of rows returned
if($rows) {
while ($row = mysqli_fetch_array($result)) {
echo ‘ID:’. $row[‘id’]. ‘<br>’;

Question 6.
What is meant by Mitakshara Law?
Answer:
Mitakshara is one of the schools belonging to Hindu law. The Mitakshara is a legal treatise on inheritance, written by Vijnaneshwara a scholar in the Western Chaiukya court in the 12th century. It became one of the most influential texts in Hindu law, and its principles regarding property distribution, property rights, and succession are still in practice across most of India except for West Bengal and Assam where the Dayabhaga system is practiced.

A salient feature is the principle of division of ancestral property held by. the Hindu joint family. Partition of such landholding among offsprings is possible even with the father still living, unlike the Dayabhaga system. Inheritance is based on the principle of propinquity i.e.‘the nearest in blood relationship will get the property. The system of devolution of property is by survivorship. The share of coparceners in the joint family property is not definite or ascertainable, as their shares are fluctuating with births and deaths of the coparceners.

Question 7.
What is meant by Dayabhaga Law?
Answer:
The Dayabhaga is a Hindu law treatise written by which primarily focuses on inheritance procedure. The Dayabhaga was the strongest authority in Modern British Indian courts in the Bengal region of India, although this has changed due to the passage of the Hindu Succession Act of 1956 and subsequent revisions to the act. Based on Jimutavahana’s criticisms of the Mitaksara, it is thought that his work is precluded by the Mitaksara.

Question 1.
Write the features System define Functions.
Answer:
System Defined Functions: A function is already created by system it is a reusable piece or block of code that performs a specific action. Functions can either return values when called or can simply perform an operation without returning any value.

Features of System defined functions:

1. System defined functions are otherwise called as predefined or built-in functions.
2. PHP has over 700 built in functions that performs different tasks.
3. Built in functions are functions that exists in PHP installation package.

Question 2.

Part IV

Explain in detail

Question 1.
Explain Function concepts in PHP.
Answer:
Functions in PHP
In most the programming language, a block of segments in a program that performs specific operation tasks (Insert, Execute, Delete, Calculate, etc.). This segment is also known as Function. A Function is a type of subroutine or procedure in a program.

Function will be executed by a call to the Function and the Function returns any data type values or NULL value to called Function in the part of the respective program.
The Function can be divided into three types as follows:

1. User-defined Function,
2. Pre-defined or System or built-in Function, and
3. Parameterized Function.

1. User-Defined Function:
User-Defined Function (UDF) in PHP gives a privilege to the user to write own specific operation inside of existing program module. Two important steps the Programmer has to create for users to define Functions are Function declaration and Function calling.

2. System Define Functions:
A function is already created by system it is a reusable piece or block of code that performs a specific action. Functions can either return values when called or can simply perform an operation without returning any value.

3. Parameterized Function:
PHP Parameterized functions are the functions with parameters or arguments.

Question 2.
Discuss in detail User-defined Functions.
Answer:

• User-Defined Function (UDF) in PHP givesa privilege to user to write own specific operation inside of existing program module.
• Two important steps the Programmer has to cre-ate for users define Functions are:

Function Declaration

• A user-defined Function declaration begins with the keyword “function”.
• User can write any custom logic inside the function block.

Syntax:
function functionName()
{
Custom Logic code to be executed;
}

Function Calling:

• A function declaration part will be executed by a ! call to the function.
• Programmer has to create Function Calling part j inside the respective program.

Syntax:
functionName();

Example:
<?php
function insertMsg() {
echo “Student Details Inserted Successfully!”;
}
insertMsg(); // call the function
?>

Question 3.
Explain the Multidimensional Array.
Answer:
Multidimensional Arrays:

1. A multidimensional array is an array containing one or more arrays.
2. PHP understands multidimensional arrays that are two, three, four, five, or more levels deep.
3. However, arrays more than three levels deep are hard to manage for most people.

Example:
<?php
// A two-dimensional array Sstudent-array
(
array(“Iniyan”, 100,96),
array(“Kavin”,60,59),
array(“Nilani”,1313,139)
);
echo $$student[0][0].“: Tamil Mark: “.$student [0][1]English mark: “.$student [0] [2].”<br>”;

echo $$student[1][0].“: Tamil Mark: “.$student [1][1].”. English mark: “.$student [1] [2].”<br>”;

echo $$student[2][0].“: Tamil Mark: “.$student [2][1]English mark: “.$student [2] [2].”<br>”;
?>

Question 4.
Explain Array concepts and their types.
Answer:
Array is a concept that stores more than one value of same data type (homogeneous) insingle array variable. They are 3 types of array con¬cepts in PHP.

1. Indexed Arrays,
2. Associative Array and
3. Multi-Dimensional Array.

Indexed Arrays

Arrays with numeric index for the available values in array variable which contains keyvalue pair as user / developer can take the values using keys.

Associative Arrays

• Associative arrays are a key-value pair data structure.
• Instead of having storing data in alinear array, with associative arrays you can store your data in a collection and assign it aunique key which you may use for referencing your data.

Multidimensional Arrays

• A multidimensional array is an array containing one or more arrays.
• PHP understands multidimensional arrays that are two, three, four, five, or more levels deep.
• However, arrays more than three levels deep are hard to manage for most people.

Question 5.
Explain Indexed array and Associatearray in PHP.
Answer:
Indexed Arrays:
Arrays with numeric index for the available values in array variable which contains key value pair as user / developer can take the values using keys.
Example:
<?php
$teacher_name=array(“Iniyan”, “Kavin”, “Nilani”);
echo “The students name are “ . $teacher_name[0]. “, “ . $$teacher_name[l]. “ and” . $teacher_name[2].
?>

Associative Arrays:

1. Associative arrays are a key-value pair data structure.
2. Instead of having storing data in a, linear array, with associative arrays you can store your data.

Example:
<?php
$Marks=array(“Student1”=>“35”,“Student2”==>“17”,“Student3”=>“43”);
echo “Student1 mark is” . $Marks[‘Student1’]. “ is eligible for qualification”;
echo “Student2 mark is” . $Marks[‘Student2’]. “ is not eligible for qualification”;
