There's probably a better way, but you could add 0 to the number to force it to be treated as a number:
CODE
<?php
$x=$_POST['URbet'];
if ($x > 0 ){
$x=$x+0;
echo "<br>You bet: ".$x."<br>";
}
?>
<html>
<form action="<?php echo $php_self ?>" method="post">
Please enter your bet: <input type="integer" size= 15 name="URbet" /><br>
<input type="submit" value="Submit" />
</form>
</html>
