PHP wrapper for the Crocodoc API
crocodoc-php is a PHP wrapper for the Crocodoc API. The Crocodoc API lets you upload documents and then generate secure and customized viewing sessions for them. Our API is based on REST principles and generally returns JSON encoded responses, and in PHP are converted to associative arrays unless otherwise noted.
First, get the library. Navigate into the folder you want to keep the library in. We suggest adding the library as a submodule in your git project.
git submodule add firstname.lastname@example.org:crocodoc/crocodoc-php.git
You can also get the library by cloning or downloading.
git clone email@example.com:crocodoc/crocodoc-php.git
wget https://github.com/crocodoc/crocodoc-php/zipball/master -O crocodoc-php.zip unzip crocodoc-php.zip mv crocodoc-crocodoc-php-* crocodoc-php
Require the library into any of your PHP files:
You can see a number of examples on how to use this library in examples.php. These examples are interactive and you can run this file to see crocodoc-php in action.
To run these examples, open up examples.php and change this line to show your API token:
$exampleApiToken = 'YOUR_API_TOKEN';
Save the file, make sure the example-files directory is writeable, and then run examples.php:
You should see 15 examples run with output in your terminal. You can inspect the examples.php code to see each API call being used.
To start using crocodoc-php in your code, set your API token:
And now you can start using the methods in CrocodocDocument, CrocodocDownload, CrocodocSession.

Errors are handled by throwing exceptions. We throw instances of CrocodocException.
Note that any Crocodoc API call can throw an exception. When making API calls, put them in a try/catch block. You can see examples.php to see working code for each method using try/catch blocks.
These methods allow you to upload, check the status of, and delete documents.
To upload a document, use CrocodocDocument::upload(). Pass in a url (as a string) or a file resource object. This function returns a UUID of the file.
// with a url $uuid = CrocodocDocument::upload($url); // with a file $fileHandle = fopen($filePath, 'r'); $uuid = CrocodocDocument::upload($fileHandle);
To check the status of one or more documents, use CrocodocDocument::status(). Pass in the UUID of the file or an array of UUIDS you want to check the status of. This function returns an associative array containing a "status" string" and a "viewable" boolean. If you passed in an array instead of a string, this function returns an array of associative arrays containing the status for each file.
// $status contains $status['status'] and $status['viewable'] $status = CrocodocDocument::status($uuid); // $statuses contains an array of $status associative arrays $statuses = CrocodocDocument::status(array($uuid, $uuid2));
To delete a document, use CrocodocDocument::delete(). Pass in the UUID of the file you want to delete. This function returns a boolean of whether the document was successfully deleted or not.
$deleted = CrocodocDocument::delete($uuid);
These methods allow you to download documents from Crocodoc in different ways. You can download originals, PDFs, extracted text, and thumbnails.
To download a document, use CrocodocDownload::document(). Pass in the uuid, an optional boolean of whether or not the file should be downloaded as a PDF, an optional boolean or whether or not the file should be annotated, and an optional filter string. This function returns the file contents as a string, which you probably want to save to a file.
// with no optional arguments $file = CrocodocDownload::document($uuid); fwrite($fileHandle, $file); // with all optional arguments $file = CrocodocDownload::document($uuid, true, true, 'all'); fwrite($fileHandle, $file);
To download a thumbnail, use CrocodocDownload::thumbnail(). Pass in the uuid and optionally the width and height. This function returns the file contents as a string, which you probably want to save to a file.
// with no optional size arguments $thumbnail = CrocodocDownload::thumbnail($uuid); fwrite($fileHandle, $thumbnail); // with optional size arguments (width 77, height 100) $thumbnail = CrocodocDownload::thumbnail($uuid, 77, 100); fwrite($fileHandle, $thumbnail);
To download extracted text from a document, use CrocodocDownload::text(). Pass in the uuid. This function returns the extracted text as a string.
$text = CrocodocDownload::text($uuid);
The session method allows you to create a session for viewing documents in a secure manner.
To get a session key, use CrocodocSession::create(). Pass in the uuid and optionally a params associative array. The params array can contain an "isEditable" boolean, a "user" associative array with "id" and "name" fields, a "filter" string, a "sidebar" string, and booleans for "isAdmin", "isDownloadable", "isCopyprotected", and "isDemo". This function returns a session key.
// without optional params $sessionKey = CrocodocSession::create($uuid); // with optional params $sessionKey = CrocodocSession::create($uuid, array( 'isEditable' => true, 'user' => array( 'id' => 1, 'name' => 'John Crocodile', ), 'filter' => 'all', 'isAdmin' => true, 'isDownloadable' => true, 'isCopyprotected' => false, 'isDemo' => false, 'sidebar' => 'visible' ));
