Okay...
First:
Checking if $shiny equals 0:
if ($shiny == 0) {
But that's already been discussed.
If you _realy_ want to check if the assignment succeeded:
if (($shiny = 0) == 0) {
Try the following example:
-----
$a = "Hello";
$b = "Wold";
if ($b == $a)
print "Yes, b equals a<BR>\n";
else
print "No, b doesn't equal a<BR>\n";
if (($b = $a) == $a)
print "Yes... now b equals a<BR>\n";
else
print "Oops... b still doesn't equal a!<BR>\n";
-----
Output will be:
No, b doesn't equal a
Yes... now b equals a
