php - fatal error mysql和登录表单

Question

我正在尝试让这个页面正常工作。 它是 HTML 和 CSS 的登录页面。 这是代码，但是当我尝试运行它时，它说

"Fatal error, maximum of 30 seconds exceeded.... on line 29"

<?
$DBhost = "localhost";
$DBuser = "bestparty";
$DBpass = "";
$DBName = "my_bestparty";


$usr = $_POST['Username'];
$pwd = $_POST["Password"];


    mysql_connect($DBhost,$DBuser,$DBpass) or die("Impossibile collegarsi al server");
    @mysql_select_db("$DBName") or die("Impossibile connettersi al database $DBName");



$sqlquery = "SELECT * FROM `Utenti`";
$result = mysql_query($sqlquery);
$number = mysql_num_rows($result);

$i = 0;

while ($i < $number) {

      $username[$i] = mysql_result($result,$i,"username");
      $password[$i] = mysql_result($result,$i,"password");



}
  if ($username[$i] == $usr && $password[$i] == $pwd) {
            echo"NELLA";
      }
      else {
          echo" ERRORE ";
      }

?>

你永远不会增加 $i 所以你有一个无限循环因为 $i 将总是小于 $number。您还需要将 if/else 语句移动到 while 循环中。

while ($i < $number) {
    $username[$i] = mysql_result($result,$i,"username");
    $password[$i] = mysql_result($result,$i,"password");
    // Move this block into your while loop
    if ($username[$i] == $usr && $password[$i] == $pwd) {
        echo"NELLA";
    }
    else {
        echo" ERRORE ";
    }
    $i++; // <-- ADD THIS
}
