Retrive list of documents from issuu.com site without using limit

Question

I am using http://issuu.com site in laravel for uploading documents and retrieving listing of it. I have a problem in fetching list from site. I want to get all records from http://issuu.com. I have used code

   $issuu = new Issuu('--my API key--', '--my API secret--');
   $documents = new Documents($issuu);
   $documentsList = $documents->list();

using above code i only get 0 to 9 records from all document list. I want to retrieve all records from that site.How can i get all documents list those are uploaded on that site?? can anyone please help me!

As documented here, the Documents->list() method takes parameters for the start index and page size, which default to 0 and 10 respectively (i.e. you get the first 10 results, starting from result #0). The maximum page size is 30, so if you have more document than that you'll need to make multiple requests to get all of them.

There's a good blog post here explaining API pagination, including how to get all results from a paged API. The crux of it is as follows (pseudocode, so you'll need to translate it to PHP and your API):

allResults = empty list
nextStart = 0
pageSize = 30
do {
    newResults = request $pageSize more results, starting at $nextStart
    add $newResults to $allResults
    nextStart = highest index in $newResults + 1
} while ($newResults indicates that there are more results)

The condition of the do...while loop will depend on your API. Some will include something like hasMore: true/false in their response, some will require you to keep going until you get zero results, etc.
