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：致命错误：允许的内存大小为33554432字节耗尽（尝试分配93个字节）

我尝试使用ini_set（）增加内存限制，但它仍然无法在96M下运行。我的代码错误是什么让它需要这么多内存？我该如何解决这个问题？

Answer 1

可能循环的条件永远不会评估为假？

Answer 2

正如其他人所说，你创造了一个无限循环。请改用for loop。

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;
  }
}

考虑一下：在你的while循环中，你测试是否$_POST['additional_contact1'] != ''。但你永远不会再改变这个价值。因此，一旦它为!= ''，while循环中的条件总是计算为true。

你可能有一个无限循环，它消耗内存，直到没有更多的内存可用。

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

如果这三个值在体内没有变化，那么你就创造了并且引入了循环。您可能希望使用if，但我不了解整个上下文。

php中允许的内存大小为33554432字节耗尽（试图分配93字节）错误
