FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

roach-php-bundle

Symfony bundle for Roach PHP.

Latest Stable Version PHP Version Require Tests Build Status Scrutinizer Code Quality Code Coverage License

Roach is a complete web scraping toolkit for PHP. It is a shameless clone heavily inspired by the popular Scrapy package for Python.

The Symfony bundle mostly provides the necessary container bindings for the various services Roach uses, as well as making certain configuration options available via a config file. To learn about how to actually start using Roach itself, check out the rest of the documentation.

Installing the Symfony bundle

Add nelexa/roach-php-bundle to your composer.json file:

Available Commands

The Symfony bundle of Roach registers a few console commands to make out development experience as pleasant as possible.

Run spider

After that, you will get the entire list of available spiders.

Simply select the desired spider (▼ or ▲) or enter its number and press Enter.

You can pass as the first argument the name spider class name to run or its alias. For example, if you have a class App\Spider\GoogleSpider, then you can pass the following aliases: GoogleSpider, google_spider or google.

Sometimes it is useful to override the number of concurrent requests and the pre-request delay. To do this, you can pass the --concurrency and --delay options.

These options override the $concurrency and $requestDelay public properties of your spider.

Add the --output (-o) option and you can save the collected data to a JSON file.

Starting the REPL

Roach ships with an interactive shell (often called Read-Evaluate-Print-Loop, or Repl for short) which makes prototyping our spiders a breeze. We can use the provided roach:shell command to launch a new Repl session.
