Printing even integers

greeneel

Hi,

This is what im trying to accomplish: I want when the form is submitted , to print every even integer less than the users age but added to that I would like for for code to do this no matter what age is put into the form field..
Is this posssible?

Thx in advance.

Here are the pages..

1st page

<html>
<body>
<form action="welcome.php" method="POST">
Your name: <input type="text" name="name" /><br>
Your age: &nbsp;&nbsp;&nbsp;<input type="text" name="age" />
<input type="submit" />
</form>
</body>
</html>

2nd Page..

<html>
<body>
<?php
if ($_POST['name']== "Chris")
{       

	echo "Welcome chris!";
}
else 
{
	echo " Welcome <br><br>";
	echo " Sorry, but you are not Chris";
}
?>
You are <?php echo $_POST["age"]; ?> years old!
</body>
</html>

You should just be able to loop through using the age entered adding 2 each time i.e

$userAge = $_POST['age'];
$age = 2;

while($age < $userAge)
{
echo $age
$age = $age + 2
}

I've always likes convoluting threads with overly complicated ways of doing things, so you can just ignore this post. But I thought using an array might be a nifty way of doing this as well.

$age   = 13;
$start = 0;

$array = range($start, $age);
echo implode(', ', array_filter($array, 'even'));

function even($num) {
   return ($num % 2 == 0);
}

Hi,

Is it possible to have the code print even integers for any age that is put into the age field?
e.g If the age 31 is put in and submitted the even integers that will print would be from 2,4,6,8 up to 30 and if age 100 is put in it would also know to print integers from 2,4,6,8, up to 100? Without having a preset limit ? if u understand what im saying?

Both these ways should give you all the even numbers up to the age you have entered. Do they work?
