使用PHP删除AmazonS3中的文件夹

从S3中删除文件夹及其所有文件的最佳方法是使用API deleteMatchingObjects()

$s3 = S3Client::factory(...);
$s3->deleteMatchingObjects('YOUR_BUCKET_NAME', '/some/dir');

请考虑@FranciscoCarmona的评论，我在这里报道以提供证据：

只需注意一件事。如果您在"一些"；目录，该目录也将删除该文件。所以这是不对的。你将必须添加一个正则表达式。$33->deleteMatchingObjects（'YOUR_BUCKET_NAME'，'/some/dir'，'/^some/dir//'）；

S3没有传统上认为的文件系统上的"文件夹"（一些S3客户端只是很好地使S3看起来有文件夹）。这些/实际上是文件名的一部分。

因此，API中没有"删除文件夹"选项。您只需要删除每个具有images/2012/...前缀的单独文件。

更新：

这可以通过AmazonS3PHP客户端中的delete_all_objects方法来实现。只需在第二个参数中指定"/^images'/2012'//"作为regex前缀（第一个参数是您的bucket名称）。

$s3 = new Aws'S3'Client([ 'region' => 'us-west-2', 'version' => 'latest' ]); 
$listObjectsParams = ['Bucket' => 'foo', 'Prefix' => 'starts/with/']; 
// Asynchronously delete 
$delete = Aws'S3'BatchDelete::fromListObjects($s3, $listObjectsParams); 
// Force synchronous completion $delete->delete();
$promise = $delete->promise(); 

这里有一个函数，它将执行您想要执行的操作。

/**
*   This function will delete a directory.  It first needs to look up all objects with the specified directory
*   and then delete the objects.
*/
function Amazon_s3_delete_dir($dir){
    $s3 = new AmazonS3();
    //the $dir is the path to the directory including the directory
    // the directories need to have a / at the end.  
    // Clear it just in case it may or may not be there and then add it back in.
            $dir = rtrim($dir, "/");
            $dir = ltrim($dir, "/");
            $dir = $dir . "/";
    //get list of directories
        $response = $s3->get_object_list(YOUR_A3_BUCKET, array(
           'prefix' => $dir
        ));

    //delete each 
        foreach ($response as $v) {
            $s3->delete_object(YOUR_A3_BUCKET, $v);
        }//foreach
    return true;
}//function

使用：如果我想删除目录foo

Amazon_s3_delete_dir("path/to/directory/foo/");

我已经测试过了，它可以工作2019-05-28

function Amazon_s3_delete_dir($delPath, $s3, $bucket) {
//the $dir is the path to the directory including the directory
// the directories need to have a / at the end.  
// Clear it just in case it may or may not be there and then add it back in.
$dir = rtrim($dir, "/");
$dir = ltrim($dir, "/");
$dir = $dir . "/";
$response = $s3->getIterator(
        'ListObjects',
        [
            'Bucket' => $bucket,
            'Prefix' => $delPath
        ]
);
//delete each 
foreach ($response as $object) {
    $fileName = $object['Key'];
    $s3->deleteObject([
        'Bucket' => $bucket,
        'Key' => $fileName
    ]);
}//foreach
    return true;
 }//function

用法：

$delPath = $myDir . $theFolderName . "/";        
Amazon_s3_delete_dir($delPath, $s3, $bucket);
