我编写了 html 和 php 代码来创建一个简单的上传文件表单。此代码用于将文件从同一台计算机上传到 localhost，但是如何将其更改为从 Google 图片上传？

这有点粗略，但它有效。

在文件选择页面中添加另一个块。

<!-- use a url to get the file -->
<form action="upload_move_file.php" method="post">
<input type="text" name="url">
<input type="submit" value="Get file from url"/>
</form>

然后在您的 upload_move_file.php 中放置一个适用于 url 而不是系统上传的部分。

/* make a folder to wite the downloads to and make it accessible 
** write permission for the web user */
$path = "files";
$uploaddir = $path.'/' ;

/* if your form sent the url, use something like this */
if (isset($_POST['url'])){
    $url_string = $_POST['url'];

    /* you will need the name from the url and image type */
    $name = substr($url_string , strrpos($url_string ,"/") + 1 ) ;
    $extension = substr($name , strrpos($name ,".") + 1 ) ;

    /* download and store the image in a temp file */
    $img = file_get_contents($url_string);

    /* Write the file over to the new name */
    $uploadfile = $path ."/". $name;
    file_put_contents($uploadfile, $img);

    /* you will need the file size */
    $img_size = filesize($path ."/". $name);    

    /* You could try loading that stuff into FILES array to 
    ** trick the upload script.

    $_FILES['picture_file']['name'] = $name;
    $_FILES['picture_file']['type'] = "image/$extension";
    $_FILES['picture_file']['size'] = $img_size;
    $_FILES['picture_file']['tmp_name'] = $uploadfile;
    $_FILES['picture_file']['error'] = '';

    OR just show it */

    die('Success!
      <center>
        <br />
        <img src="'.$uploadfile.'" 
        width="250" height="175" border="3" />
    </center>');


} /* else use the other idea that handled the local image. */
