can't upload and unlink image php

本文关键字：取消链接图像 php 可以 | 更新日期: 2023-09-27

我在服务器中上传和取消链接图像的过程中遇到任何问题。我使用此脚本上传图像：

move_uploaded_file($source, $directory);

但是，我有警告：

警告：move_uploaded_file（34160518200001.jpg）[function.move上载的文件]：无法打开流：HTTP包装不支持可写连接

并且我使用这个脚本来取消图像链接:

unlink('a34160518200001.jpg');

但我有警告：

警告：unlink（）[function.unlink]：http不允许取消的链接

我希望任何人都能帮助我，谢谢大师

下面是一个开始的示例：

    <?php
        // NOT NECESSARY TO CREATE VARIABLES FOR THE IMAGES DIRECTORY
        // AND THE IMAGE BUT THIS HELPS ILLUSTRATE THE PROCESS.. ;-)
        $imagesDir  = "path/to_the/images/folder";
        $image      = "the_image_to_upload.jpg";
        // FIRST chmod THE IMAGES DIRECTORY TO HAVE THE PERMISSIONS YOU WANT:
        chmod($imagesDir, 0777);        
        // THEN UPLOAD THE IMAGE:
        move_uploaded_file($image, $imagesDir);
        // TO DELETE (unlink) A FILE [IMAGE IN THIS EXAMPLE]
        $image2Delete = "the_image_to_delete.png";
        // CHMOD THE IMAGE TOO... BE SURE ALSO THAT THE CONTAINING DIRECTORY
        // FOR THIS IMAGE ALSO HAS THE RIGHT PERMISSIONS:
        chmod($image2Delete, 0777);
        // THEN DELETE THE IMAGE...
        unlink($image2Delete);
