Can PHP do "reference" but not "copy" on variables in classes?

You might try:
<pre>
function increment_variable( &$counter ) {
  $counter ++;

}
$number_of_hits = 0;
while( $number_of_hits < 100 ) {
  increment_variable( $number_of_hits );
}
</pre>

The key is to use the ampersand in the function name.
