How can the mysql_data_seek function be used to reset a query in PHP, and what are the correct parameters to pass to it?
When using the mysql_data_seek function in PHP, you can reset a query result set to the beginning so that you can iterate through it again. This can be useful if you need to loop through the results multiple times without re-executing the query. To use the mysql_data_seek function, you need to pass the result resource and the row number you want to seek to as parameters.
// Assuming $result is the result resource from a MySQL query
// Reset the result set to the beginning
mysql_data_seek($result, 0);
// Now you can iterate through the results again from the beginning
while ($row = mysql_fetch_assoc($result)) {
// Process each row as needed
}
