List objects by using PHP SDK (PHP SDK V1) - Object Storage Service

This topic describes how to list all objects, a specific number of objects, and objects whose names contain a specific prefix in an Object Storage Service (OSS) bucket.

Usage notes

In this topic, the public endpoint of the China (Hangzhou) region is used. To access OSS from other Alibaba Cloud services in the same region, use an internal endpoint. For details about supported regions and endpoints, see Regions and endpoints.
In this topic, an OSSClient instance is created by using an OSS endpoint. If you want to create an OSSClient instance by using custom domain names or Security Token Service (STS), see Create an OSSClient instance.
To list objects, you must have the oss:ListObjects permission. For more information, see Attach a custom policy to a RAM user.

List objects

You can call the listObjects or listObjectsV2 method to list objects in the root directory of a specified bucket. Subdirectories and objects in the subdirectories are not listed.

Use the listObjects method

The following code shows how to call the listObjects method to list objects in the root directory of a bucket named examplebucket. Subdirectories and objects in the subdirectories are not listed. By default, 100 objects are returned.

Specify the encoding of object names

If an object name contains special characters, you must encode the object name for transmission. OSS supports only URL encoding.

Single quotation marks (')
Double quotation marks (")
Ampersands (&)
Angle brackets (< >)
Enumeration commas (、)
Chinese characters

You can call the listObjects or listObjectsV2 method to specify the encoding of object names.

Use the listObjects method

The following code shows how to call the listObjects method to specify the encoding of object names.

Simulate directories

OSS uses a flat structure where all data is stored as objects. To simulate a directory, you can create a 0-byte object whose name ends with a forward slash (/). You can upload and download this object. The OSS console displays objects whose names end with a forward slash (/) as directories.

You can specify the delimiter and prefix parameters to list objects by directory.

If you set prefix to a directory name in the request, the objects and subdirectories whose names contain the prefix are listed.
If you specify a prefix and set delimiter to a forward slash (/) in the request, the objects and subdirectories whose names start with the specified prefix in the directory are listed. Each subdirectory is listed as a single result element in CommonPrefixes. The objects and directories in these subdirectories are not listed.

For example, a bucket contains the following objects: oss.jpg, fun/test.jpg, fun/movie/001.avi, and fun/movie/007.avi. The forward slash (/) is specified as the directory delimiter. The following examples describe how to list objects in simulated directories.
