Hello,
I am a core PHP developer since 4 years and i have developed many things using PHP and other languages like, Websites, Online stores, Web scraping scripts, PDF parser, Invoicing applications, custom CRMs, CMSs, micro frameworks, and many custom application according to the need of my clients. I also know languages like JAVA, C, C++, MySQL, JS etc well enough.
I can show you a live example for generating PDFs , if you want.
I have developed few PHP classes which generates PHP files on the server but does not save it on the server but download/send to the user device.
You can contact me anytime over chat to discuss your new and unique requirements for your project.
Thanks
Meeshal k
