Create PHP script to convert PDF to PNG file using imagemagic

Write a PHP script, which will utilize [login to view URL] to convert a PDF file to a PNG file. All text on the PDF file needs to be readable after the conversion even if the PDF file has 10 pages. Please make a method in the PHP script, which has a PDF filename as input parameter and the PNG file name as return value. I also need you to change the file names of both the PDF file and the PNG file so that they no longer contain special characters and no spaces (these should be replaced with "_". Please convert the following special characters: æ -> ae, Æ -> Ae, ø -> oe, Ø -> Oe, å -> aa, Å -> Aa. Please remove all other special characters (non alpha-numerics). I will accept a bid of less than 20$ immediately. I expect delivery within 2 days.
