multiple uses of fetch_array()

[AsscBB]

I'm trying to write some code where I scan through an array multiple times. The symptoms of my code lead me to belive that only the first call to fetch_array() is being used. Are there any limts on how many times you can run fetch_array against the same array?

PHP Code:

.
.
.
while($get_result=$db->fetch_array($get_results)) 
{
    //do stuff 1
}

//do stuff 2

while($get_result=$db->fetch_array($get_results)) 
{
    //do stuff 3
}

//do stuff 4

while($get_result=$db->fetch_array($get_results)) 
{
    //do stuff 5
}
.
.
. 


My when I activate my plug-in, it looks like "do stuff 3" and "do stuff 5" are being ignored.

If this is a limitation, any suggestions on an alternative?

Thanks!
