Question 35.
Explain the Database error handling and management process in PHP.
Answer:
Error handling is the process of catching errors raised by our program and then taking appropriate action. If we would handle errors properly then it may lead to many unforeseen consequences. Its very simple in PHP to handle errors.
Using die ( ) function:
While writing your PHP program you should check all possible error condition before going ahead and take appropriate action when required.
Eg:
<?php
if (!file_exists (“/tmp/test. txt”) )
{
die (“file not found”);
}
else{
$file=fopen (“/tmp/test. txt”, “r”) ;
Print “opend file successfully”;
)
?>

Question 36.
Defining custom error handling process.
Answer:
This function must be able to handle a minimum of two parameters (error level and error message) but can accept upto five parameters.
Syntax: error_function(error_level, error_message, error_file, error_line,error_context) ;

Error Report Levels:
These error report levels are the different types of error the user – defined error handler can be used for EWARNING, ENOTICE, EUSERERROR, E_USER WARNING, EUSERNOTICE, E_RECOVERABLE_ERROR,-E_ALL etc.,
Error Logging – By default, PHP sends an error log to the server’s logging system or a file.

Send an Error Message by E-mail: We will send an E-mail with an error message and end the script, if a specific errors occurs.

Question 37.
Explain in details types of MySQL connection method in PHP.
Answer:
PHP program, which will explain how to connect from your PHP to MYSQ1 database.

• Connect using mysqli extension.
• Connect using PDO.
• Connect using traditional legacy MYSQl_functions.

(i) Connect from PHP using mysqli extension:
Cent os, php MySQli is already part of the php mysql package.
Create the following mysqli. php file under the Apache Document Root:
<?php
$conn = new mysqli (“localhost”, “root”, “DB pass”, “stuff”); .
mysqli – This function will initiate a new connection using MySQli extension. This function will take four arguments.
(a) hostname where the MySQl database is running.
(b) MySQl username to connect.
(c) Password for the MySQl user.
(d) MySQl database to connect.

(ii) Connect from PHP MySQL PDO extension:
PDO_MySQL drive implements the PDO interface provided by PHP to connect from your PHP program to MySQL database.
Create the following MySQl_pdo.php file under our Apache document Root:
<?php
$conn = new PDO (“mysql: host = localhost: dbname=stuff”, “root”, “DBPass”) ;
$conn set Attribute (PDO:: ATTR_ERRMODE, PDO:: ERRMODE_EXCEPTION);

• New PDO – This will create a new PDO object. The Three arguments are.
(a) MySQl connect string.
(b) MySQl username to connect.
(c) Password for the MySQl user.

(iii) Connect from PHP using legacy mysql_function:
Use this method only if we are using an older version of PHP and cannot upgrade it to the new version.
Create the following mysql legacy. php file under the Apache (isset($_POST [‘reg_user’]))

<?php
$Conn = mysql_connect (‘localhost’, ‘root’, ‘DB Pass’ ) ; mysql_select_db (“stuff”) ;
mysql_connect function takes three arguments.
(a) Hostname where the MySQL database is running.
(b) MySQl username to connect.
(c) Password for the MySQl user.

Question 38.
Explain MySQLi Queries with examples.
Answer:
mysqli_query( ) is the function that executes the MySQLi queries.
Squery is the SQL query to be executed. Slinkidentifier is optional, it can be used to pass in the server connection link.
MySQLi function can be used to execute the following query type:
• INSERT, SELECT, UPDATE, DELETE.
Syntax: <?php
mysqli_query(“Connection Object”, “Query”)
where,
Mysqli_query – is the function that executes the SQL queries.
Query – is the SQL query to be executed.
Connection object – used to pass in the server link.
Eg:
$con = mysqli_connect (“localhost”, “my_user”, “my_password”, “student_DB”) ;
$sql = “select student_name, student_age FROM .
student”; MySQli_query (Scon, $sql)

Question 39.

Answer:
Server, php
<?php
Session_start();
// initializing variables
Susername = ” “;
Serrors = Array();
//connect to the database
$db = mysqli_connect (‘localhost’, ‘root’, ‘ ‘registration’);
//Register user
if (isset ($_POST [‘reg_user’])}
{
//receive all input values from the form
$username = mysqli_real_escape_string($db, $POST[‘username’]);
$password_1 = mysqli_real_escape_string($db, $POST[‘password_1’]);
$password_2 = mysqli_real_escape_string($db, $POST[‘password_2’]);
//form validation
if(empty($username))
{array_push($errors, “username is required”);}
if(empty($password_1))
{array_push($errors, “password is required”);}
if ($password_1 = $password_2) ‘
{array_push ($errors, “The two passwords do not match”) ; }
//First check the database to make sure
$user_check_query = “SELECT*FROM users WHERE
username = ‘$username’ ;
$result = mysqli_query($db, $user_check_query);
$user = mysqli_fetch_assoc($result);
if ($user)
{
if($user)[‘user name’]=== $username)
{
{array_push($errors, “Username already exists”);
}
}
//Register user if there are no errors in the form
if (count ($errors)==0)
{
$password = md5($password_1);
$query = “INSERT INTO users (username, password) VALUES( ‘$username’, ‘$password’) “;
mysqli_query($db, $query);
$_SESSION[‘username’] = $username
$_SESSI0N[‘success’] = “we are now logged in”;
header(‘location:index.PhP’ ) ;
}
}
//. . .

Question 40.

Answer:
//student Registration form code-server side program using php .
<?php
require(‘db.php’);
//Form submited Insert values
If(isset($_REQUEST[‘username’]))
{
$username = mysqli_real_escape_string($con, $username);
$email = stripslashes ($_REQUEST[’email’]);
$email = mysqli_real_escape_string($con, $email);
$password = stripslashes($_REQUEST[‘Password’]);
$password = mysqli_real_escape_string($con, $password);
$Dob = date(“y-m-d H:i:s”);
$query = insert into ‘student’ (username, password email, Dob)
Values (’$username’ , ‘” .md5 ($password) , ‘$email’, ($dob’)
Sresult = mysqli_query($con, $query); if($result)
{
echo “<div class form’>
<h3> you are registered successfully </h3>
<br/>click here to <a href = ‘login.php’> Login</a> </div>”;
}
}
else
{
?>
<div class = “form”>
<h1> Registration </h1>
<form name = “registration” action = ” ” method = “POST”>
<input type = “text” name = “username” placeholder = “Username” required/>
<input type> = “email” name = “email” placeholder = “Email” required/>
<input type = “password” name = “password” placeholder = “password” required/>
<input type = “DOB” name = “Date of Birth” Placeholder = “DOB” required/>
