two things, do you want to match with image name or with the whole image.
if you want to match with simply name, that must be easy.
but if you want to match with a random image, then the story will get little bit harder.

some question regarding your post(I'm not going to solve your problem but I can suggest you something that may help you)
1. what are you going to do?
2. why do you need to store image in database, why not in filesystem ?
3. why do you need image matching things?

and if you tell us the whole story, we may suggest you some way that might help you to solve your own problem.
the thing is, Forhad already said, this forum is not kind of "get home work done" type forum. We simply help each other. That's all. and definitely we are very much helpful.

Hello there,
Matching images may be a bit difficult than matching texts. For example, you can macth exact text or use RegEx for texts, but this is not possible for images. Two similar looking images may have completely different binary representations.

Fortunately, solution exist for this problem. What you're looking for, is known as Content-based image retrieval. To the best of my knowlwdge, there is no existing PHP library for achieving this.

However, you can build a library of your own if you're interested. This type of matching can be easily done using a neural network named Self-organizing map. Codes for SOM in PHP should not be hard to find in the internet. Modifying a SOM library should achieve this easily.
