PHP cURL Login and SEO Majestic/aHrefs Function

Hey Guys, What im building as a simple PHP system to grab data for me, this is 1/6 project, please see the others as well through my profile. Time & Quality is more important than cost. Your Script used as part of a cronjob to grab link data for a specific url. We will be collecting data from the following sources: - Open Site Explorer - Blekko - Webmaster Tools ([login to view URL]<<REQUESTEDURL>>) - Majestic SEO - Bing Webmaster ([login to view URL]<<PROFILEURL>>&linkurl=<<REQUESTEDURL>>) - aHrefs For now i only want the functions for each one of the above so no looping one to the next. We will store a clean list of URL's that link to the given URL and stored into a file for each one of these, of which the file path/name will be given. The following rules need to be applied: - PHP 5.3 Preferred and Definatley PHP5 - All the Separate Sources need to be in Separate Functions - Each Function i need to be able to give the following varibles (URL, FILE PATH, API/LOGIN DETAILS) = If File Path is not set or NULL then return Variable else return nothing = Add a $debug = TRUE / FALSE to see the script progress = All debug output needs to work with Output Buffering to show live debug - I will provide NO login and NO API keys for testing - CURL for Login to Google and Bing Webmaster tools, i dont want to mess arround with Oauth etc. - Script cannot timeout As the script runs for each one of these, i will like to see through the debug output to the screen the connectivity, the % of download for the file, the file size header etc all being displayed. Please clean code, no time wasters... im a developer myself but working on the bigger programming work. Please reply 'RedBlueGreen' to join the project More projects for right person, i.e. multi-threaded job executer for these modules and more modules as such. If you can only do some please let me know, also if you know more sources for backlink data please also let me know! Thanks Vincent
