What is the best way to check if table exists in DynamoDb?

I would appreciate it if the code would be in PHP.

Either active or not.

With dynamodb cli you can do it very simple as follows:

aws dynamodb describe-table --table-name "my-table"

If the table exists it returns

0 -- Command was successful. There were no errors thrown by either the CLI or by the service the request was made to.

If the table does not exist it returns

255 -- Command failed. There were errors thrown by either the CLI or by the service the request was made to.
