How to reset mysql pointer back to the first row in PHP?

I have 2 while loops in my PHP script that processes a list of data from a database.

$results = mysql_query("SELECT * FROM myTable");
while ($result = mysql_fetch_object($results))  {
    // do stuff
}

reset($results);
while ($result = mysql_fetch_object($results))  {
    // do some more stuff
}

However, the reset() function is not resetting my pointer within the MySQL resource. In fact, it generates an error:

“Warning: reset() [function.reset]: Passed variable is not an array or
object in /home/cs179_team13/public_html/timeTests/results.php on
line 133.”

Why? How do I reset a PHP pointer for a MySQL resource?

Answer 1

You can use the function mysql_data_seek.

bool mysql_data_seek ( resource $result , int $row_number )
