PDF splitter in php 7x

PDF splitter in php 7x I need a class that works this way. $pdf = new pdfSplit(); $pdf->setFiles("[login to view URL]", "[login to view URL]", 1-10, "[login to view URL]", 11-22, "[login to view URL]", 22-30 ); //new pdfs will be put in the split dir. Original pdf will stay in current dir. $pdf->outputDir(/split/); $pdf->split(); The class should get a large pdf and split it into smaller pdfs base on the parameters in setFiles. [login to view URL] is the PDF that needs to be split. (30 pages) [login to view URL] is part of [login to view URL] (pages 1-10) [login to view URL] is part of [login to view URL] (pages 10-22) [login to view URL] is part of [login to view URL] (pages 22-30) [login to view URL] could be any size. Up to hundreds of pages if not thousands of pages, ie no limit. And should be able to be broken down into how ever many smaller pdfs needed as long as the smaller pdfs number does not exceeds the total number of pages in the original pdf. ie A 100 page PDF can only be broken down to 100 one page pdfs. I will be using this in a larger project and will probably be reworking as need so please make the code as readable as possible. I dont care if you use some code from the web or libraries but it needs to be production/enterprise level. Thanks
