致命错误：第140行的/home/news-insert.php中允许的内存大小536870912字节已用完（尝试分配4294967296字节）
我在做一个项目，我在做一个页面，应该做更新和定期插入工作。我在其他地方找到了代码，并一直在修改它以用于我的项目。不管怎样，我修复了许多错误，但我在第140行一直出现内存泄漏 代码如下：致命错误：第140行的/home/news-insert.php中允许的内存大小536870912字节已用完（尝试分配4294967296字节）,php,html,mysqli,Php,Html,Mysqli,我在做一个项目，我在做一个页面，应该做更新和定期插入工作。我在其他地方找到了代码，并一直在修改它以用于我的项目。不管怎样，我修复了许多错误，但我在第140行一直出现内存泄漏 代码如下： <?php /* Allows the user to both create new records and edit existing records */ // connect to the database include("include

尝试增加php.ini中的内存限制。默认设置为128MB。小错误可能导致大问题
if($stmt = $conn->prepare("SELECT ID, title, summary, entry FROM news WHERE ID=?"))
{
$stmt->bind_param("i", $id); // <-- this is the problem
$stmt->execute();

列不是长文本。我把我的从长文本改为中文本，它解决了同样的问题
MySQL v5.6.33请将您的代码编辑到您的问题中。如果在每行的开头添加4个空格，它将保持其格式。1,2,3,4，对不起，我放弃了第140行是什么？第140行是这一行：'code'$stmt->bind_result（$id，$title，$summary，$entry）；它位于“编辑记录”部分，在更新行之后。我将它添加到pastebin，其他人编辑了它。我把它放在pastebin上，因为它显示了线条。你看到的是它在我的记事本上的格式++你真的想让我在200多行中添加4个空格吗？我添加了4个空格。有帮助吗？我试过了，不管我放多大，它都会用光。如果是那样的话，请查看你的内存使用情况。。如果有足够的内存为您的php服务。。。阅读这篇文章，可能会有助于你在回答之前读得更好一些。问题本身已经表明，限制设置为500mb，因此OP显然知道在哪里可以找到该选项。我尝试了许多上限和下限，但实际上，限制是什么并不重要。但正如Blizz善意地指出的，似乎我在绑定部分失败了，所以它试图选择整个表，而不是表太大。使用1代替I会导致另一个错误，并且仍然会泄漏内存。但是：id导致错误：无法准备SQL语句请确保更正所有语句。。。我认为如果我解释我对php有一些经验会有所帮助，但在大多数情况下我是一个新手。另外，近两周来，我一直盯着看，试图找出我做错了什么。哈哈，所以你的陈述找到并纠正我所有的陈述并不一定有帮助D
