[SOLVED] IGNORE STRING

[howitzer]

Code goes like this:

IF($variable<=0 and $variable>=10){echo "something"}

If i enter letters for $variable,statement will be true and application will continue.

How can i disable string input for $variable and use only numbers?

You'd have to use javascript validation.

 

Of course, you could also use it this way:

 

<?php

if (isnumeric($variable))
      {
             if ($variable <= 0 && $variable >= 10) { echo "something"; }
      }
else
      {
             echo "Not a number.";
      }

?>
