为什么不是'；t upload.php是否将文件上载到目录？

非常感谢您花时间阅读并回答，我们有一个php文件，它可以执行，它将url打印为index.php？uploady，就像我们在头部分编写代码时标记的那样。它似乎执行得很好。唯一的问题，也是一个非常大的问题是，它没有将文件从文件目标变量放置到服务器文件夹中，它似乎没有将本地文件放置在服务器中的任何位置。我们的代码如下：

<form action="upload.php" method="POST" enctype="multipart/form-data">
        <input type="file" name="file">
        <button type="submit" name="submit">
            UPLOAD
        </button>
    </form>

<?php 
ini_set('display_errors', 1); ini_set('display_startup_errors', 1); error_reporting(E_ALL);
if (isset($_POST['submit'])) {
    $file = $_FILES['file'];

    $fileName = $_FILES['file']['name'];
    $fileTmpName = $_FILES['file']['tmp_name'];
    $fileSize = $_FILES['file']['size'];
    $fileError = $_FILES['file']['error'];
    $fileType = $_FILES['file']['type'];

    $fileExt = explode('.', $fileName);
    $fileActualExt = strtolower(end($fileExt));

    $allowed = array('jpg', 'jpeg', 'png', 'gif');

    if (in_array($fileActualExt, $allowed)) {
        if ($fileError === 0) {
            if ($fileSize < 200000000) {
                $fileNameNew = uniqid('', true).".".$fileActualExt;
                $fileDestination = '/public_html/styleuploads'.$fileNameNew;
                move_uploaded_file($fileTmpName, $fileDestination);
                header("Location: index.php?uploadyay");
                exit;
            } else echo "Opps, your file is too big! It needs to be smaller than 200 Megabytes";
        } else {
            echo "There was an error uploading your file";
        }
    } else {
        echo "You can not upload files of that type";
    }
}
?>

您需要检查目标目录权限，确保它是可写的。检查$fileDestination是否为绝对路径（我对此表示怀疑），并检查目标目录中的权限。这是可行的，但它不会进入正确的文件夹。在我看来，这是一个小得多的问题。因此，我现在实际上正在服务器中获取上传的文件，只是为了与目的地一起玩

<form action="upload.php" method="POST" enctype="multipart/form-data">
        <input type="file" name="file">
        <button type="submit" name="submit">
            UPLOAD
        </button>
    </form>

<?php 
ini_set('display_errors', 1); ini_set('display_startup_errors', 1); error_reporting(E_ALL);
if (isset($_POST['submit'])) {
    $file = $_FILES['file'];

    $fileName = $_FILES['file']['name'];
    $fileTmpName = $_FILES['file']['tmp_name'];
    $fileSize = $_FILES['file']['size'];
    $fileError = $_FILES['file']['error'];
    $fileType = $_FILES['file']['type'];

    $fileExt = explode('.', $fileName);
    $fileActualExt = strtolower(end($fileExt));

    $allowed = array('jpg', 'jpeg', 'png', 'gif');

    if (in_array($fileActualExt, $allowed)) {
        if ($fileError === 0) {
            if ($fileSize < 200000000) {
                $fileNameNew = uniqid('', true).".".$fileActualExt;
                $fileDestination = $_SERVER['DOCUMENT_ROOT'].'/public_html/';
                $moved = move_uploaded_file($fileTmpName, $fileDestination.'styleuploads'.$fileNameNew);
                header("Location: index.php?uploadyay");
                exit;
            } else echo "Opps, your file is too big! It needs to be smaller than 200 Megabytes";
        } else {
            echo "There was an error uploading your file";
        }
    } else {
        echo "You can not upload files of that type";
    }
