<?
// Start snipit 1
$sql = "SELECT * from <table>";
$result = mysql_query($sql);
while ($row = mysql_fetch_assoc($result)) {
// do stuff with $row
}
mysql_data_seek($result, 0); //关键是这儿
while ($row = mysql_fetch_assoc($result)) {
// do other stuff with $row
}
?>
// Start snipit 1
$sql = "SELECT * from <table>";
$result = mysql_query($sql);
while ($row = mysql_fetch_assoc($result)) {
// do stuff with $row
}
mysql_data_seek($result, 0); //关键是这儿
while ($row = mysql_fetch_assoc($result)) {
// do other stuff with $row
}
?>
