Hello, I have only one simple question..
I'm using this method to get the values from the text box:

if(isset($_POST["Submit"]) && $_POST["Submit"]=="Submit")
{
$add = $_POST['textbox'] ;
}

But I don't know how to write the source for this:

If the value from the textbox ($add) is "Hello" then.. do something.
I think it could be nicely done with IF, but I dont know how to write this..

Can someone help me, please?

Regards,
Lab.
