php - php中允许的内存大小为33554432字节耗尽(尝试分配93字节)错误

Question

我插入了以下代码:

$counter = 1;
while($_POST['additional_contact1'] != '' || $_POST['additional_contact2'] != '' || $_POST['additional_contact3'] != '') {
  if($_POST['additional_contact' . $counter] != '') {
    $_SESSION['contact'][$counter]['additional_contact'] = $_POST['additional_contact' . $counter];
    $_SESSION['contact'][$counter]['additional_int_prefix'] = $_POST['additional_int_prefix' . $counter];
    $_SESSION['contact'][$counter]['additional_prefix'] = $_POST['additional_prefix' . $counter];
    $_SESSION['contact'][$counter]['additional_first'] = $_POST['additional_first' . $counter];
    $_SESSION['contact'][$counter]['additional_last'] = $_POST['additional_last' . $counter];
  } else {
    $_SESSION['contact'][$counter]['additional_contact'] = null;
    $_SESSION['contact'][$counter]['additional_int_prefix'] = null;
    $_SESSION['contact'][$counter]['additional_prefix'] = null;
    $_SESSION['contact'][$counter]['additional_first'] = null;
    $_SESSION['contact'][$counter]['additional_last'] = null;
  }

$counter++;
}

我收到此错误: fatal error :允许的内存大小为 33554432 字节已用尽(尝试分配 93 字节)

我尝试使用 ini_set() 增加内存限制，但它仍然无法在 96M 下工作。我的代码做错了什么使它需要这么多内存？我该如何解决这个问题？

正如其他人所说，您创建了一个无限循环。使用 for loop而是。

for($counter = 1; $counter <= 3; $counter++) {
  if($_POST['additional_contact' . $counter] != '') {
    $_SESSION['contact'][$counter]['additional_contact'] = $_POST['additional_contact' . $counter];
    $_SESSION['contact'][$counter]['additional_int_prefix'] = $_POST['additional_int_prefix' . $counter];
    $_SESSION['contact'][$counter]['additional_prefix'] = $_POST['additional_prefix' . $counter];
    $_SESSION['contact'][$counter]['additional_first'] = $_POST['additional_first' . $counter];
    $_SESSION['contact'][$counter]['additional_last'] = $_POST['additional_last' . $counter];
  } else {
    $_SESSION['contact'][$counter]['additional_contact'] = null;
    $_SESSION['contact'][$counter]['additional_int_prefix'] = null;
    $_SESSION['contact'][$counter]['additional_prefix'] = null;
    $_SESSION['contact'][$counter]['additional_first'] = null;
    $_SESSION['contact'][$counter]['additional_last'] = null;
  }
}

想一想:在您的 while 循环中，您测试是否 $_POST['additional_contact1'] != '' 。但是你再也不会改变那个值了。所以一旦它是 != ''，while 循环中的条件总是计算为 true。
