A little help with a php file to an image

pedroteixeira07

Hello there!

I have this PHP file that performs some queries to my database. Besides that I need the result of this PHP to be an image file that is stored in the server. How can I do this? Any suggestions?

How can I make the result of my PHP an image file ?
I've thought of echoing the link but the most correct way would be to echo the picture itself as a MIME type or something like that.. Please HELP ..desperate :S

dagon

are you wanting the text to be a graphic (why?) or are you storing images in the db?

Hey again.. I'm creating an application in Android on which I make an HTTP POST to a PHP.
In that PHP I select some pictures from my database according to some keywords and a date range.
The result of that query should be the picture itself which I want the PHP to post back to the Android.

Ps: The pictures are stored in my server, and the only thing that the database stores is the link to them.

I'd like to try sending the link with PHP to Android, I think it will work to make the Android retrieve the picture from the link.

But to be easier I'd prefer the PHP to end the picture itself. MAybe sending a header? I'm not sure how to work with content_types :/

You could use [man]header/man to send the appropriate header (e.g., Content-type: image/png), then use [man]readfile/man to read the image file and output it.

That would be great! Can you you show me some example of how to do it? Sorry for the waisted time :S

For example:

<?php
header('Content-type: image/png');

readfile('http://phpbuilder.com/board/image.php?u=145249');

Thank you very much. So at this point. The Readfile is the output of this php file right? thank you

laserlight

Yes. You might want to place an [man]exit[/man] right after the readfile() in a larger script so as to avoid the possibility of there being more (unexpected) output later that corrupts the image.
