Edit 1 php file

I have 1 php file which scrapes the Google ads on the search engine ranking page. The output is a file which can be downloaded as xml. It's working with selection of proxies. The output is all active advertisers in the google result. 1: I need to have output in UTF8 format because sometime output have weirds chars. 2: In the input file I need a new option to add a google spreadsheet link, where a) the output automatically is sent to in a new tab of the spreadsheet. Name of the new tab is the date of the export f/e 08-09. and b) A possibility to set a frequency on the time the export to google spreadsheets is generated. For example every 3 hours, twice a day, every day, every 7 days See attached file for input page
