PHP图像处理

Question

因此，我创建了一个小脚本，允许用户上传其汽车的多个图像。然后，我处理这些图像并将文件路径存储在数据库中，并在“vehicleImages”文件夹内创建一个文件夹来存储图像。不过，我一直遇到一个问题，所以正如你所看到的，我检查该文件夹是否存在，如果不存在，我就创建一个。然后图像得到处理，理论上应该存储在该文件夹内。

我遇到的问题是，它创建的文件夹就像它应该的那样，例如XX00VVV。但是，它不是将图像存储在“vehcileImages/XX00VVV”内，而是将图像存储在“vehicleImages”内，而不是在正确的文件夹内。我检查了服务器，文件夹“XX00VVV”确实被创建，但由于某种原因图像没有存储在里面。我认为这是我改变目标路径的地方，但我不明白为什么。有人可以给我一些关于我哪里出错的指示/提示吗？

    $imagePath = "../../images/vehicleImages/".$vehicleReg;
$fileName = $vehicleReg; 
if (!file_exists($imagePath)) {
    mkdir($imagePath, 0777, true);
}

//Image Upload Section

$j = 0; //Variable for indexing uploaded image 

    $target_path = $imagePath; //Declaring Path for uploaded images
    for ($i = 0; $i < count($_FILES['file']['name']); $i++) { //loop to get individual element from the array

        $validextensions = array("jpeg", "jpg", "png"); //Extensions which are allowed
        $ext = explode('.', basename($_FILES['file']['name'][$i])); //explode file name from dot(.) 
        $file_extension = end($ext); //store extensions in the variable

        $target_path = $target_path.md5(uniqid()).
        ".".$ext[count($ext) - 1]; //set the target path with a new name of image
        $j = $j + 1; //increment the number of uploaded images according to the files in array       

        if (($_FILES["file"]["size"][$i] < 100000000) //Approx. 100kb files can be uploaded.
            && in_array($file_extension, $validextensions)) {
            if (move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) { //if file moved to uploads folder
                echo $j.
                ').<span id="noerror">Image Uploaded Successfully!.</span><br/><br/>';
            } else { //if file was not moved.
                echo $j.
                ').<span id="error">Please Try Again!.</span><br/><br/>';
            }
        } else { //if file size and file type was incorrect.
            echo $j.
            ').<span id="error">***Invalid File Size or Type***</span><br/><br/>';
        }
    }

//End Image Upload Section

所以问题出在代码的第一行$imagePath

$imagePath = "../../images/vehicleImages/".$vehicleReg;

尝试将 ."/" 添加到行尾 像这样:

$imagePath = "../../images/vehicleImages/".$vehicleReg."/";

<小时/>

解决方案的解释是:

当你没有在路径末尾添加 / 时，你可以将它与 filename 合并，例如 XX00VVVfilenam.png
