Hi,
I've been trying to find a tutorial on how to upload/download an image to/from a mySQL database by using php and android.
I've made a database on 000WebHost, I've uploaded string data (name,username,password,email), but I want my app to have the ability to upload/download images.
Does anyone know a good tutorial (video/text maybe) on how this can be done?
Thanks.
Php allows you to create forms which support image upload functionality. This is generally done via a multi-part post message to a form that you create. Check that out here
You can try storing the image into a MySQL db as a base64 encoded string.
However, this is not a good idea from scalability perspective.
You can checkout this tutorial here which has an android sample as well.

In php, I need to upload an large image; however it needs to upload in minimal seconds.
We have number of fields in a form with image upload. user can upload large images, using normal upload it will take long time. So I would like to use some background uploading using jQuery ajax. please provide some other solutions to make it easy.
Thanks in advance!
Use Dropzonejs, it supports Ajax upload, upload progression, drag & drop files and also multi-file upload.

A while ago I built a PHP application for a local radio. They get requests from listeners and then put them into the application. The application then shows the DJ what the listener's requests are.
Now that all works fine but they have to build a music database by themselves which I use to search for music. My question is:
Is there an online music database that I can use cross scripting with soap/xml or something similar? I prefer XML but if there is a good database which gives the result in other format that won't be a problem.
I searched Google for this but I only find information how to download illegal mp3 files. I just need to find the music information like: album name, artist name and song title. Not the mp3/wma/etc file itself.
You may find something useable here http://en.wikipedia.org/wiki/List_of_online_music_databases ?

We are developing PHP & MySQL based application. We distribute a registration form in PDF format. After filling form, user will upload PDF form to our application to register. We want to extract registration data in PDF form from PHP and save these data to database.
Can someone point me PHP classes for extracting field value from PDF form?
An alternative could be using an external program like http://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/ and so something like:
$ pdftk file.pdf dump_data_fields
and then process the output. However, this would involve a lot of parsing logic and output processing. Plus, if you cannot install binaries on your server, never mind. :)
It might be just simpler to do as hoppa mentioned.
Edit: This question might be a duplicate of The best pratice to parse PDF forms fields with PHP5 that question has an interesting comment!

I am working on creating a website which will allow users to update a table using Javascript.
What I am looking for is a way to allow the user to export the table as an image (jpg, png etc.) or a PDF once it has been modified.
If there is a similar thread or topic please let me know, I don't really know where to start here. If you can recommend background reading that would be great too.
This is not something that can really be done client side (without installing software on the clients, of course). You will need to generate this PDF server-side.
How you do that depends on the language and platform you are using.
There are a couple open source PDF librarys you can use;
SharPDF, PDFClown, iTextSharp just to name a few...

This is not a question about the names of libraries for making graphs.
I have a project that needed a way to make graphs with data that comes from MySQL.
My question is: A library that provide a good integration and flexibility with external data, in this case MySQL data?
I need to calculate averages, make pie charts, change the data in real time, etc.
I would prefer a library that doesn't use JPEG images in final graphs. I would like something like
http://raphaeljs.com/analytics.html (anyone know if there's MySQL integration for this library?).
I saw the Google Charts API but I don't like the idea of not having library control on my server, and I read that it has limitations.
I would let jquery or dojo render the data in a graph therefore saving computing power on the server take a look at these links
