PHP/SQL Lab 1 Consider the banking example we used in the SQL in-class exercises:

branch (branch-name, branch-city, assets)

customer (customer-name, customer-street, customer-city)

account (account-number, branch-name, balance)

loan (loan-number, branch-name, amount)

depositor (customer-name, account-number)

borrower (customer-name, loan-number)

Write PHP code for the following problems:

1. Create a php file to display the names and cities of customers who have an account at Downtown branch from the web.

2. Create the corresponding html and php files so that a user can insert the following customer into the database from a web browser. After the insertion, display all the customers from the web. “Jane Doe”, “401 Rosemont Ave”, “Frederick” Submission:

Submit a softcopy of the html and php files and a document containing screenshots of web outputs with URL included for both problems

Answer 1:

<?php
// you have to give username,password and databasename of your SQL Server bellow
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
// Retrive name and cities of customers who have an acount at Downtown branch
$sql = "select customer-name, customer-city from customer where customer-name in (select distinct customer-name from depositor, account where depositor.account-number=account.account-number and account.branch-name='Downtown')";
$result = $conn->query($sql);

if ($result->num_rows > 0)
{
// output result in each row
while($row = $result->fetch_assoc())
{
echo "Name: ". $row['customer-name']. " " . $row["customer-city"] . "<br>";
}
}

else
{
echo "0 results";
}

$conn->close();
?>

Answer 2:

HTML file

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>

<body>

<form name="form1" method="post" action="insert_ac.php">
<table width="366" border="5">
<tr>
<td> <strong>Enter Customer Name:</strong></td>
<td> <input type="text" name="name"> </td>
</tr>
<tr>

</tr>
<tr>
<td><strong> Enter Customer City: </strong></td>
<td> <input type="text" name="city"> </td>
</tr>

</table>
</form>

PHP file ie PHP code to insert customer data into database File name : insert_ac.php

<?php

$host="localhost"; // Host name
$username=""; // Mysql username
$password=""; // Mysql password
$db_name="test"; // Database name

// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");

// Get values from form
$name=$_POST['name'];
$street=$_POST['street'];
$city=$_POST['city'];

// Insert data into mysql
$sql="INSERT INTO customer(customer-name, customer-street, customer-city)VALUES('$name', '$street', '$city')";
$result=mysql_query($sql);

// if successfully insert data into database, displays message "Successful".
if($result){
echo "Successful";
echo "<BR>";
echo "<a href='insert.php'>Back to main page</a>";
}

else {
echo "ERROR";
}
?>

<?php
// close connection
mysql_close();
?>

PHP code to display all customers from the database file name :displaycustomer.php

<?php

// you have to give username,password and databasename of your SQL Server bellow
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
// Retrieve all the customer information
$sql = "SELECT * FROM customer";
$result = mysqli_query($conn, $sql);

if (mysqli_num_rows($result) > 0)
{
// output data of each row
while($row = mysqli_fetch_assoc($result))
   {
       $customername=$row['customer-name'] ;
       $customerstreet=$row['customer-street'] ;
       $customercity=$row['customer-city'] ;
       echo $customername.",".$customerstreet.",".$customercity;

For today's lab we will be using the Car Object Class which we built in Lab 1. I have attached my solution if you would prefer to use my solution instead of your own solution. We will working on remembering how to build sub-classes and user interfaces. So we will be creating new Java files for: An Interface called GreenHouseGasser Requires a method called CO2() which returns how much carbon dioxide the Object produces. Make sure to update Car so...

In C++ In this lab we will be creating a stack class and a queue class, both with a hybrid method combining linked list and arrays in addition to the Stack methods(push, pop, peek, isEmpty, size, print) and Queue methods (enqueue, deque, peek, isEmpty, size, print). DO NOT USE ANY LIBRARY, implement each method from scratch. Both the Stack and Queue classes should be generic classes. Don't forget to comment your code.
