PHP - Extract Data from other web pages(repost)

Require a php page that will extract specific pieces of data from other URLs. There are 3 main types of pages with different formats : Type 1 - approx. 10 different URLs - all the same format example : <[login to view URL]^DJI&d=t> Extract the 'Value' and 'Day's Range' ( split into 2 parts ). Save the extracted data into a comma delimited text file ( sample of required layout will be supplied ). Type 2 - 1 page only example : <[login to view URL]> Extract the 'Price' for the 'Brent Oil' and the 'Gold' values. Type 3 - 1 master page with multiple sub-pages example : <[login to view URL]> Extract a list of all URLs contained in the main body section ( the 'master page' ). There may be up to 150 sub-pages referenced in the 'master page'. Then, extract the heading and body text from each of the extracted URLs ( the sub-pages ). Check the extracted heading and body text of each sub-page for the existance of any one of 400 keywords ( should be read from a text file that we upload ). If the article contains any of the keywords, save the article into a text file. ( example URLs are examples only - may not be the final URLs to be used ) ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
