同一个查询语句：
fetchAll()：
array(1) {
[0]=> array(6) {
["id"]=> string(2) "15"
[0]=> string(2) "15"
["lot_sellid"]=> string(20) "00000000000000003877"
[1]=> string(20) "00000000000000003877"
["lotteryid"]=> string(2) "D8"
[2]=> string(2) "D8"
}
}
mysql_fetch_array():
array(6) {
[0]=> string(2) "15"
["id"]=> string(2) "15"
[1]=> string(20) "00000000000000003877"
["lot_sellid"]=> string(20) "00000000000000003877"
[2]=> string(2) "D8"
["lotteryid"]=> string(2) "D8"
}
