Question

我正在尝试读取.CSV文件并以HTML格式的表格格式打印。在页面的末尾是一个注释文本字段，其中注释被提交并保存在数据库中。

当我在本地测试下面的代码时，它运行正常。当我试图在linux服务器上运行它时，它在第一次打开时打印出来很好，但是当我按下提交保存注释时，页面刷新并且表格不打印。给出“为foreach（）提供的无效参数”错误。（注意：这不会在本地发生，我可以提交我想要的所有内容，但不会返回错误。）

我搜索了stackoverflow，似乎大多数这些问题都与将变量声明为数组有关。但是，对我来说这似乎很奇怪，因为代码第一次运行正常而没有错误，但是一旦我提交它就会返回错误。

更新：下面发布的文件的完整代码。

    window.onunload = refreshParent;
    function refreshParent() {
        window.opener.location.reload();
    }

如果您形成，并且采用发布表单的脚本不在同一路径上，那么

 $f = fopen("analyze/".$case."/".$patientID."/report.csv", "r");

不会打开同一个文件。

好的，我认为你的问题是$ case变量。如果没有请求，则$ case为空（“”）。所以上面的行将打开“analyze /// report.csv”正如你所看到的那样取决于这段代码

$case = "";
if(isset($_REQUEST['case'])) {
$case = $_REQUEST['case'];
}

为foreach（）提供的参数无效，在本地但不是远程工作
