1. assigns some information inputted by the user to a variable
2. Checks to see if it is a string
3. If it is a string it prompts the user to input a number
4. if it is a number, it performs a counting algorithm
I think i made a mistake with the control structures. Either I'm nesting them wrong or I'm using the wrong ones.
Please check out my code, thanks.
Code: Select all
<?php
$count = $_POST['count'];
if (is_string($count)
{
echo "That is not a number!";
}
else
{
while ($count <=1000)
{
echo "$count <br />";
$count = $count *(-2);
}
}
?>
