    There are classes to extract PDF to text but also return the original page of the text I am not sure if the existing ones can do it.

    PHP PDF to HTML: Convert PDF to HTML using Poppler

    This class can convert PDF to HTML using Poppler program.

    It can take the path of the Poppler program tools and execute several operations to extract information from PDF documents.

    Currently the class can convert whole PDF documents or individual pages to HTML, get the document information, return the page count, etc..

    Several parameters can be configured like the the preferred format of the pictures inside the document, zoom scale, whether to use images or CSS inline within the HTML or as external files, etc..

    I have made a class to extract text contents from pdf files ; however it does not take care of the page number. Maybe it could be a first step ?

      It would be better if you could count pages to also give the page number of each text block. Is that difficult?

      well, it could range from somewhere between tedious and a nightmare... :-) I'm kidding ; in fact, I already put that on my to-do list when posting my initial answer because, although my original concern was only extracting text, I thought it was a good idea to be able to locate text in the whole document.

      I will add a "Pages" array property that will contain the text of individual pages. I will also add a GetPageOf ( $offset ) that will return the page number given a byte offset in the Text property. And maybe, some methods to simply find the page number(s) of some text.

      I think everything should be ready by the end of this week.

      Great. That would make your package innovative. There are already classes to extract text from PDF but none would get the pages of the text objects.

      Hi everybody,

      I'm glad to announce that the PdfToText class is now able to retrieve the page number of any text located in a pdf document.

      7 new methods are available to retrieve this information : GetPageFromOffset, text_strpos/text_stripos, document_strpos/document_stripos, and text_match/document_match (see README.md).

      There is also a Pages array property that holds the text contents of individual pages in the document

      That is great. I have not seen a package, PHP or other language that could do that.

      Hello Christian, I have very large PDFs (200MB) and I can not extract all the text from them. Would you have any solution for this? Within these PDFs there are images too, so the size is excessive. I just need the text. Your function can read the file but can not process. I await your suggestion.
