Php getting number from user

Question

See more:

I want to write a php program that prompts user to enter as many numbers as he/she wishes. The termination of number entry should be done by the letter N or n. Once the number entry is completed the program is expected to print the max, min, average, mode and median of the numbers alongside with a histogram.

I just want to learn how to take number from a user as many number as he/she wishes and make the termination.

What I have tried:

HTML

<html>
<body>
<form action="example.php" method="post>
Enter a number:
<input type="number_format" name="number"> <br> <br>
<input type="submit" value="submit">
</form>
</body>
</html>

------

PHP

<?php

$num = $_POST=['number'];



?>

Hi! First of all Im a C# dev and has't used PHP for a couple of years now. But PHP is mostly used as a server-side script, you can use a command-promt but this is rare in PHP. (PHP has a strong association to C, so most devs create librarys in C instead)

What Im trying to say is that you don't need a terminator, looking at your code you don't seem to create an RIA application. If you are, you "need" to use a JavaScript to find the terminator and then submit the numbers to the server, but JavaScript can do all you want to do. But I will show you the basic code to get you going. (Im not adding code for your operations like max and min)

This code will take the numbers in a string divided by a comma, you can change this to a space as well if you wish.

PHP

$delimiter = ',' // The charecter to divide the numbers
// $delimiter = ' ' Use this line to divide numbers by a space

$numbers = explode($delimiter, $_POST['number']);

You can find the documentation of the explode function at php.net wich takes an string and break it into an Array. The first argument is the char that divides the numbers. But I still Think you should do all this in jQuery or in another JavaScript library.
