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++;
}

我收到了这个错误：致命错误：允许的内存大小为 33554432 字节已用尽（试图分配 93 字节）

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

正如其他人所说，您创建了一个无限循环。请改用for循环。

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：在你的 while 循环中，你测试是否$_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。

也许循环的条件永远不会评估为假？

您可能在那里有一个无限循环，它会消耗内存，直到没有更多可用内存为止。

while($_POST['additional_contact1'] != '' || $_POST['additional_contact2'] != '' || $_POST['additional_contact3'] != '') {

如果这三个值在正文中没有变化，则您创建了 inifite 循环。您可能想if改用，但我不知道整个上下文。
