Bool 0 not displayed PHP

[Tsarevich]

I have XAMPP the 1.6.6 version. The trouble is that the boolean value of 1 is displayed but 0 is not. For example:

<?php 
$raw = 18;
$result = ( $raw == 18 );
echo $result;
?>

then the value 1 is displayed but:

<?php 
$raw = 17;
$result = ( $raw == 18 );
echo $result;
?>

then 0 is not displayed! What to do?

I don't exactly understand what you're trying to do...
but this looks kinda awkward, its like saying 1 = 2 o_O...
if you want a logical way and output try this :

<?php

$raw = 18;

if( $raw == 18 )
{
$result = 1;
echo $result;
}
else
{
$result = 0;
echo $result;
}
