Hi i'm currently developing a console mode php program that displays all positive odd numbers which are less than or equal to whatever the user inputs so for example if the user inputs 16 it should show up like this,

1,3,5,7,9,11,13,15

Here is the code i have so far,

#!/usr/local/bin/php -q

<?php

//phpset3_1.php

require ("phpio");

$count = 1;

print("\n ");

print ("enter a number : ");

$count = input();

while ($count <=$)

{

  print("\n ");

  print ($count);

  $count = $count +2;

}

print("\n\n");

?>

Anyone tell me what ive done wrong and how to fix it. Much appreciated if you can

Can you tell use the error you are getting?

[kentona]

The error i'm getting is the odd numbers keep adding like an infinite loop so if the user types in 16 it will go past that and keep adding by 2 till i stop it.

Thanks.

you have an error in

while ($count <=$)

you need a variable name after your $ sign. as well, you are using the same variable for counting as for max value...

I tried doing it but now it just displays whatever number the user inputs. Would you be able to show me exactly which parts of the code i need to change and what i should change it too.

Thanks. :)

[Orjan]

just do a $input = input(); and then while ($count < $input)...
do you understand why and how that would work?

[kentona]

Ah yes i do understand it now whatever the $input number is will be the result for the $count.

Thanks for all the help Orjan :)
