Serach Engine URL Scraper

I need a tool that will scrape the urls from google search results pages, and write these urls to a text file. I am envisaging a php, server based solution, however I am open to other options if you belive they are more feasable. The starting page should have space to enter the search term and to specify how many results (or results pages) to collect. Any search terms can be entered into this box and submitted. These search terms determine which urls the script will collect from google. For example, if the following is entered into the text box: "Send an Email to the Forum Administrator Contact Us" The script should collect the url, complete with http:// from the page below, as well all subsequent pages until X number of urls have been collected. [login to view URL] When this process is completed, there should be a list of around 59,000 urls. Note the num=100 in the url gets google to display 100 results per page. Note how the url changes as subsequent pages of results are viewed. Google will place a temp block on a ip if too many requests are made in a certain time period. So there must be support for proxy servers built into the script. The urls should be written to a txt file with one per line. If you feel this may be a performace issue when the list gets big, I welcome suggestions e.g. 1000 per file, or even using mysql. Other Points ============= 1. Code should be commented. 2.
