PHP - Im A Beginner. Basic Php Calculator
First of all hi everyone, this is my first post as you can see. And i have my first task in PHP, now i warn you i have no experience or know-how whatsover in PHP so please bear with me.
My first task is to extend some PHP code to add some functions. the code weve been given already is capable of mutiplication of two variables x and y. Here it is anyway. 1. View the code and copy/paste it into an editor and save it to your own workspace. 2. Extend the script to perform the four basic arithmetic functions : +, -, *, / and return a result. 3. Extend the script again to move the calculations into a function and make use of this function. Code: [Select] <?php /* ====================================================== PHP Calculator example using "sticky" form (Version 1) ====================================================== Author : P Chatterjee (adopted from an original example written by C J Wallace) Purpose : To multiply 2 numbers passed from a HTML form and display the result. input: x, y : numbers calc : Calculate button pressed Date: 15 Oct 2007 */ // grab the form values from $_HTTP_POST_VARS hash extract($_GET); // first compute the output, but only if data has been input if(isset($calc)) { // $calc exists as a variable $prod = $x * $y; } else { // set defaults $x=0; $y=0; $prod=0; } ?> <html> <head> <title>PHP Calculator Example</title> </head> <body> <h3>PHP Calculator (Version 1)</h3> <p>Multiply two numbers and output the result</p> <form method="get" action="<?php print $_SERVER['PHP_SELF']; ?>"> x = <input type="text" name="x" size="5" value="<?php print $x; ?>"/> y = <input type="text" name="y" size="5" value="<?php print $y; ?>"/> <input type="submit" name="calc" value="Calculate"/> <input type="reset" name="clear" value="Clear"/> </form> <!-- print the result --> <?php if(isset($calc)) { print "<p>x * y = $prod</p>"; } ?> </body> </html> Firstly how do i run this code, i have Xamp installed if thats any good? Secondly, do i need two seperate files. i.e. calculator.php for the php code and calculator.html for the form? Thirdly i have no idea how to implement the divide, add and subtract functions. should i do a drop down menu where the user should select what operator they want? or is it more simple than that. Any help greatly appreciated. Please let me know if this post is okay. Similar TutorialsIs this possible? I have around 2 weeks for a computer science project and I want to do this in PHP. However, I have just started learning PHP, and since I'm so short on time I'm going to see if I can learn how to code this while learning basics of PHP. So basically, can anyone give me a simple and good way of starting this? I have no idea where to begin. I was thinking of doing rooms in a coordinate system with North, South, East, West buttons and a pick up item button and an attack button. So can you guys help? I would also like to know how to make buttons in HTML or anything that goes with Apache 2, I have no idea how that works. Right now I have PHP set up with Apache 2, so I can navigate to the file with the code in the browser and run the code. Im after a little bit of help with two things in my code. www.1pw.co.uk/demo2.php 1) getting an image to appear opposed to just the filename. where and how in my code should i put <img src="filename" /> in the img column of mysql database i am just listing filenames. should i wrap these in the html above instead? 2) how can i get my calculator to behave? i get the correct tally when checking out (using order.php), but as you will see from the link provided the calculator does not work properly, in demo2.php -- addtocart2.php -- Code: [Select] <?php define('INCLUDE_CHECK',1); require "../connect2.php"; if(!$_POST['img']) die("There is no such product!"); $img=mysql_real_escape_string(end(explode('/',$_POST['img']))); $row=mysql_fetch_assoc(mysql_query("SELECT * FROM internet_shop WHERE img='".$img."'")); $jsonArr = array('img' => $row['img'], 'status' => 1, 'id' => $row['id'], 'price' => $row['price'], 'txt' => ' <table width="100%" id="table_'.$row['id'].'"> <tr> <td width="40%">'.$row['img'].'</td> <td width="20%">'.$row['name'].'</td> <td width="10%">$'.$row['price'].'</td> <td width="15%"> <select name="'.$row['id'].'_cnt" id="'.$row['id'].'_cnt" onchange="change('.$row['id'].');"> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option></slect> </td> <td width="15%"><a href="#" onclick="remove('.$row['id'].');return false;" class="remove">remove</a></td> </tr> </table>');

The idea is to have x number of teams, all starting with 1000 Ranking points. If team A plays team B and wins 1-0, team A should increase by 30 points, and team B should decrease by 30 points? (I think.. ) Then to rank the teams based on their points. The main problem is, I'd like to use a form to edit the teams. I've got as far as a drop down menu to choose the teams, and then Home goals and Away goals. It will already define what is a win/draw/loss.

Website: http://novacms.vacau.com/index.php I'm trying to make a calculator for this game I play, it's fully developed, but with one bug. It doesn't do the math right. $goal = The amount of EXP (Experience Points) someone wants to get $exp = The amount of EXP they currently have $npcs_exp["exp"] = The amount of EXP the monster has But, when they enter in the information, the calculation is all screwed up. When I do it, it seems to give me the same number EACH time. The part where the calculation "goes down".

I'm not a PHP master, now i'd like to program an online calculator on my website. it's not the classical calculator with + / - / x / ln etc... but a specific, simple though, calculator. I'd like even to be able to export the results of the calculations into a xls or csv file (that would be the next step) Is that possible to do that with PHP ? or i should look more at javascript or java (dont like that idea) or flash etc... Thanks for your replies ! Hi! Need some help with a piece of code. New to this, so it is quite a pain in the ass! I need to make a code that shows the what spare change you should give back. so for example. when i put in 7 it should give back: 1 x 5 euro 1 x euro Which it does. but i have some trouble putting in the 1 euro's. for example when i put in 21 it gives back 2 x 10 euro Who can help me out?

Hello, For all purposes, I am a complete beginner. I just know the basics of passing form data through to an email, and displaying the text of a variable on the next page via ECHO, POST, etc.. My situation is that I do not know what sort of code to use to accomplish the job of what I want done. I have created a form to be used for displaying insurance information. This form allows users to select the following: To Get Started: State You Live In: Car Information: Model Year: Original Listing Price: Your Car Currently Is: Your Information: Do You Rent Or Own? Are You Married? Do You Have Children Under 18 Years Of Age? Gross Annual Household Salary Do You Have Health Insurance? How Much Are You Worth In Total Assets (Savings, Equity, Stocks, 401K, Car, Home, etc...) ------------------------ Next to each question, I have a box from which they can select their options (standard html form code). The form has an action and the method is post. Some code is displayed below.. Now so far I am able to display the text of whatever item they selected, by using Echo $_Post etc and the answer page... Here is my problem... I want to display to the user, "recommended insurance limits" based on the data they select from the drop down boxes. So... If a user lives in Alabama, and has an income of $150K+, I want to display a different answer than someone who only earns $30K and lives in Alabama, and the list goes on, (range of options for each question). I have no idea what sort of code to use to display the appropriate answer. I thought I could use the "if, elseif, else" statement, and simply do hundreds of variations on it for each state, but surely there is a more refined and less bloated code for doing such a thing? I would need to display a different answer for the user, for each separate option they choose. Example) Alabama, Model Year of 1995, Salary of $50K would be DIFFERENT then Alabama, Model Year of 2000, Salary of $50K, etc... Thank you for your time. Here is my php code. Code: [Select] <?php $state = $_POST["state"]; $modelyear = $_POST["modelyear"]; $carprice = $_POST["carprice"]; $carownership = $_POST["carownership"]; $homeownership = $_POST["homeownership"]; $marriage = $_POST["marriage"]; $childrenunder18 = $_POST["childrenunder18"]; $salary = $_POST["salary"]; $healthinsurance = $_POST["healthinsurance"]; $assets = $_POST["assets"]; ?> <?php if ($state=="Alabama") { echo "Alabama requires the following minimum insurance limits:<br /> $25,000 - Liability Per Person<br /> $50,000 - Liability For Total Persons<br /> $25,000 - Property Damage Total"; } elseif ($state=="Alaska") { echo "Alaska requires etc..."; } else { echo "You did not select a state."; } ?> hi there i am a beginner in PHP and i really would like some help with this.....
i need to make use of the date() function to retrieve the current date. Use the split() function to retrieve the day month and the year from the current date. and the calculations to display the age.
if anyone could help me with this it would be amazing.
thank you!!

Hi, I'm trying to set up a mysql database on my laptop, XP, and connect to a test database using php. I've created the database called 'testdb' with user account 'test' and password 'password. The code I'm using to try and connect to the test datase is the following; $dbconnect=mssql_connect("localhost", "test", "password"); But when I open the page in a web browser, I am getting the following error; Fatal error: Call to undefined function mssql_connect() in <file_location> I'm hoping I'm doing something simple here, but, I've looked up forums and this seems to be the code to use to connect.
