Try this code.

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Positive Negative Zero</title>
</head>

<body>
<form method="post">
<input type="text" placeholder="Input Number" name="input" value="<?=$_POST['input']?>">
<input type="submit" name="submit">
</form>

<?php 
if(isset($_POST['submit']))
{
	$input = $_POST['input'];
			
	if($input>0)
	{
		echo 'Your input is Positive';
	}			
	else if($input<0)
	{
		echo 'Your input is Negative';
	}		
	else if($input==0)
	{
		echo 'Your input is Zero';
	}
}
?>
</body>
</html>

what I had tried to ask, was I create a form to be used in science project, where results are entered as either positive
or negative. But the out put should generate the 1 for positive and the number 0 (zero) for negative.
Not sure if that tries to explain my reasoning.

Thanks
