[請益] 產生出來的亂數記錄在資料庫裡??
我亂數的寫法是（重複11個編號）
<?PHP
srand ((float) microtime() * 10000000);
$input = array ("0000000001", "0000000002", "0000000003", "0000000004",
"0000000005","0000000006","0000000007","0000000008","0000000009","0000000010","0000000011");
$rand_keys = array_rand ($input, 2);
print $input[$rand_keys[0]]."\n";
?>
產生出來的亂數 我要把它記錄在資料庫裡
我是寫這樣子的 $sql = "INSERT INTO record VALUES
(\"$rfidnumber\")"；
$sql_result = mysql_query($sql)
or die("無法執行查詢！");
可是它卻顯示"無法執行查詢" 囧OZ
為什麼會這樣...???
是我亂數那段程式沒有加上 $rfidnumber 這個東西嗎???
