 A joint list of all your crawl / bulk jobs can be fetched via:
 
-```
+```php
 $diffbot = new Diffbot('my_token');
 $jobs = $diffbot->crawl()->call();
 ```
 
 This returns a collection of all crawl and bulk jobs. Each type is represented by its own class: `JobCrawl` and `JobBulk`. It's important to note that Jobs only contain the information about the job - not the data. To get the data of a job, use the `downloadUrl` method to get the URL to the dataset:
 
-```
+```php
 $url = $job->downloadUrl("json");
 ```
