// Sample code for problem	
srand(time());
for($counter = 0; $counter<= 20 ; $counter++){
print(rand(0,5 );
print("<br>");
}

for some reason this always returns the same number as the first number returned, until the file is modified.  The first number, after that, the numbers seem to be random.  

I'm using the latest apache & php on a win2k SP2 laptop

try using a better seed for the random number, such as

srand((double) microtime() * 1000000);

this fixed the problem on my machine.
