Website Spider & Scraper

We need a spider/scraper to spider through a freelance market site like getafreelancer (don't worry, it's not getafreelancer though as they have an API already) and scrape some information from the projects.

First it will need to spider throughout the site at a reasonable speed but not as to cause any thouble with the site itself. For each project page it will pull: Project Name, Description, Type, Creation Date, End date, Budget, Project ID and place this information in 2 seperate MySQL databases (1 of them are basically a realtime backup).

This is basically how I figured out how to make the spider run so it doesn't run out of memory:

The spider will land on the index page and grab all the internal links and place those in a database table. So you'll have:

Link Status

[url removed, login to view] | Spidered

[url removed, login to view] |

[url removed, login to view] |

[url removed, login to view] |

[url removed, login to view] |

Then it will start spidering [url removed, login to view] and place all those links in the database. ie:

Link Status

[url removed, login to view] | Spidered

[url removed, login to view] | Spidered

[url removed, login to view] |

[url removed, login to view] |

[url removed, login to view] |

[url removed, login to view] |

[url removed, login to view] |

[url removed, login to view] |

[url removed, login to view] |

After that it of course spiders [url removed, login to view] grabbing the links as well as since it's a project page it'll scrape it. ie:

Link Status

[url removed, login to view] | Spidered

[url removed, login to view] | Spidered

[url removed, login to view] | Spidered & Scraped

[url removed, login to view] |

[url removed, login to view] |

[url removed, login to view] |

[url removed, login to view] |

[url removed, login to view] |

[url removed, login to view] |

By doing it this way the script won't run out of memory or use an excessive amount.

We also need a smaller version of the scraper that will watch an updates/new projects page and scrape the new projects as they appear (we can schedule this to be ran on a cron).
