I want to open an .epub document with PHP, to modify it (for example to add some text on the first page and last page) and to save it back to .epub I found some classes for saving a text into epub file, but I can't find anything about opening an epub in PHP.
epub files are just HTML+CSS files inside a ZIP archive (called the Open Container Format (OCF)) files with a different file extension :) So you can use PHP's ZipArchive class to work on the file.
There are libraries that support EPUB files. BookGlutton is one.

A Laravel-based application is converting documents (.doc, .docx, .pdf, .png, .otd, html, etc) to PDF so that they can all be merged together into a master PDF document. It is using a combination of plugins like PHPWord and DOMPDF Wrapper to do the file loading and creation. Every once and awhile, the process encounters an error due to a Word file.
ERROR: PhpOffice\PhpWord\Exception\InvalidImageException: Invalid
image: zip:// ... #word/media/image2.emf
The error is caused by an image background within the document that acts like a watermark. The PHPWord part that errors out is the PhpOffice\PhpWord\Element\Image->checkImage() method, but happens when the file is trying to be loaded.
Settings::setPdfRendererName(Settings::PDF_RENDERER_DOMPDF);
$pdfWord = IOFactory::load(storage_path() . '/app/uploads/randomfile.docx', 'Word2007');
How can the application convert a Word document, with an EMF image embedded, to a PDF?
For more code/info on how to recreate the error, a few issues exist in the Github PHPWord library.
Support EMF image #1480
Read docx error when contains image from remote url #1173
The environment-related information:
Server: Windows / IIS
PHP: 7.2.11
Laravel: 5.7.15
PHPWord: 0.15.0
EDIT:
I also tried to come at this from a different angle, to no avail. I tried using PHP's ZipArchive to unzip the docx file, remove the emf image from the document (ZipArchive::deleteName()), remove the reference to the emf image in the [Content_Types].xml (ZipArchive::getFromName()), then zip the docx file back up but that did not work. I can open the new docx file and see that the image is gone, but the PHPWord error still persists in the application.
It looks like PHPWord has a feature request open to solve this issue.

I think you're on the right path with the file alteration, there is probably a reference to the image you are missing somewhere that PHPWord is still trying to access.
I would unzip the file on your local drive and grep (search the contents of the exploded file) the directory for the file you are looking for. This will show you where else you may need to remove it from being referenced in the file.
I wanna edit epub file content in PHP to erase some text from begging of the ebook. I have tried some libraries with no success.
https://github.com/Grandt/PHPePub
https://github.com/Vaporbook/BookGluttonEpub
https://sourceforge.net/projects/oplsepublibrary
They can edit authors, isbn, description, creator, cover, etc., or create new epub file, or open epub file, but I haven't found some solution for editing content.
Do you know some easy way how to do it?
Now I know, that you can just unzip epub as simple zip file and then edit all html and css files :)
After you have done changes, just zip the files back.
I followed this tut :
http://klewos.wordpress.com/2010/04/16/using-php-to-fill-a-word-document-quick-tip/
and all is fine till i open the downloaded .doc into libre office,
instead of outputing the doc content, it shows the full xml code as content !
Just note that i would prefer to create a PDF as final document but it seems easier with doc
I should miss a step with the xml to doc ?
if someone sees a better way to do this kind of thing (my base doc is 10 pages long so i don't really want to create a line by line pdf)
Anyhelp is welcome ;)
The article does mention that particular situation:
I’ve tried to open the Word 2003 XML document in OpenOffice.org 3.1.
Unfortunately, Writer wasn’t fooled by the .doc extension and opened
the document as plain text. Only after changing the document’s
extension to .xml, the editor opened it correctly. So, the documents
are portable after all.
I have 16631 files hosted in a webserver, 2719 of them are text files that contains a list of specific files located on the server.
Using PHP, is possible to create a ZIP for each text file?
could be the text file name as ZIP file name?
I want to keep the same directory structure in the ZIP file.
Thanks in advance.
Taking the suggestion from Jeff Hines, you could use the ZipArchive class to create the zip.
In Pseudo code
Get List of Text Files in your folder
Read Text file and get list of files to add to zip
Using ZipArchive add each listed file to your new zip file.
Write flag to specify you've done this file.
You might need to run it on 10 files at a time since it may time out.
I want to automate the following:
Once a day my cronjob starts a PHP script that obtains a zipped XML file from an URL.
What would be the best way to handle this? Is there any way to directly read the XML file from within the zip file?
Right now, i'm just downloading the zipped file to the server and manually unpacking it later that day.
Any ideas? All suggestions are very much welcome.
You can use PHP's ZipArchive coupled with cURL to download and read the zip file.
Also, the ZipArchive class has a method called getStream which allows you to then use fread to access the contents without explicitly extracting the file.
The only problem I see if that the zip does have to be saved somewhere for PHP's library to read it. But, given you're already doing this, it shouldn't be an issue.
If you need an example, leave me a comment and I can write on up.
There is a collection of zip-related functions that can be used in PHP.
The problem with these is that it requires the compressed file to exist on the server (not just loaded from an external server somewhere using, for example, $file = file($url);).
If you were to save the file to your server then you could use $zip = zip_open($filename) and zip_read($zip) to process the zip file.
