如何在php中为变量上传设置我的目标文件夹?

我是php的新手,因此无法弄清楚我的问题。 我有一个HTML表单连接到提到的PHP文件。这个表格工作正常。问题出在php文件中。 HTML表单是:

>>> string = "Hello 13 World"
>>> substring = "01234567890"
>>> bool(set(string) & set(substring))
True
>>> string = 'Hello 13 world'
>>> substring = 'abc'
>>> bool(set(string) & set(substring))
False

我的php文件名为upload.php:

    <!DOCTYPE html>
    <html>
    <body>

    <form action="upload.php" method="post" enctype="multipart/form-data">
    Select image to upload:
    <input type="file" name="fileToUpload" id="fileToUpload">
    <input type="submit" value="Upload Image" name="submit">
    </form>

    </body>
    </html>

在这里,正如您在php代码的第一行中所看到的,目标目录已设置。但我希望它与一个名为

的变量
    <?php
    $uid = $_POST['uid'];
    $target_dir = "FILES OF:$uid";
    $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
    $uploadOk = 1;
    $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
    // Check if image file is a actual image or fake image
    if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
    echo "File is an image - " . $check["mime"] . ".";
    $uploadOk = 1;
    } else {
    echo "File is not an image.";
    $uploadOk = 0;
    }
    }
    ?>

链接到我的数据库中的uid字段,意思是用户名。我的意思是说我希望它将文件上传到名为&#34; FILES OF:$ uid&#34;的文件夹中。 我已经创建了这些文件夹,但想要一种文件直接进入该文件夹的方法。 有谁知道这样做的方法?

    $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
    $uploadOk = 1;
    $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
    // Check if image file is a actual image or fake image
    if(isset($_POST["submit"])) {
        $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
        if($check !== false) {
            echo "File is an image - " . $check["mime"] . ".";
            $uploadOk = 1;
        } else {
            echo "File is not an image.";
            $uploadOk = 0;
        }
    }
    // Check if file already exists
    if (file_exists($target_file)) {
        echo "Sorry, file already exists.";
        $uploadOk = 0;
    }
    // Check file size
    if ($_FILES["fileToUpload"]["size"] > 500000) {
        echo "Sorry, your file is too large.";
        $uploadOk = 0;
    }
    // Allow certain file formats
    if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
    && $imageFileType != "gif" ) {
        echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
        $uploadOk = 0;
    }
    // Check if $uploadOk is set to 0 by an error
    if ($uploadOk == 0) {
        echo "Sorry, your file was not uploaded.";
    // if everything is ok, try to upload file
    } else {
        if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
            echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
        } else {
            echo "Sorry, there was an error uploading your file.";
        }
    }
    ?>
