How to use PHP to delete Base64 format images from Qiniu Cloud Storage?

With the development of the Internet, data storage and processing have become more and more convenient. The emergence of cloud storage services provides developers with a more convenient way to store and manage data. As a well-known cloud storage service provider, Qiniu Cloud Storage provides rich functions and good performance, and is favored by the majority of developers.

When using Qiniu Cloud Storage, sometimes we need to delete images that have been uploaded to the cloud storage on the server side. If the image is stored in a database or program in Base64 format, some operations are required to delete it from cloud storage. Let’s introduce how to use PHP to delete Base64 format images from Qiniu Cloud Storage.

First, we need to obtain the URL of the picture to be deleted and the Access Key and Secret Key of Qiniu Cloud Storage. Before you begin, make sure you have the PHP SDK installed on your server and included in your code.

delete($bucket, $key);

echo "图片删除成功！";
?>

In the above code, we first need to set the Access Key and Secret Key of Qiniu Cloud Storage. Then, create an Auth object to generate credentials for Qiniu Cloud Storage. Next, set the URL of the picture to be deleted, and obtain the Bucket and Key of the picture. Then, instantiate the BucketManager object and delete the image from the cloud storage by calling the delete method.

It should be noted that the same picture may be in different Buckets, so you need to specify the correct Bucket when deleting. If you don't know which Bucket the image belongs to, you can call the listBuckets method in BucketManager to get the list of all Buckets.

Finally, delete the image from the cloud storage by calling the delete method in the above code, and output a prompt message after the deletion is successful.

To summarize, by using the Auth and BucketManager objects in the PHP SDK, combined with the Access Key and Secret Key of Qiniu Cloud Storage, we can easily delete Base64 format images in Qiniu Cloud Storage. This method allows us to better manage and process image resources in cloud storage, improving development efficiency.
