Good Morning,
I am working on creating a function that adds http://domain.com to an image/link source. Example:
I have this bit of code in a MySQL database:
here is some random text with an image<img src="http://www.webmaster-talk.com/images/image.png" alt="" /> and a <a href="index.php">link</a> and some more random text.

I would like to turn it into something like this:
here is some random text with an image<img src="http://domain.com/images/image.png" alt="" /> and a <a href="http://domain.com/index.php">link</a> and some more random text.

I am currently using str_replace like this: str_replace("<img src=\"", "<img src=\"http://domain.com", $text);

I have thought about that and I will run into a problem if I am adding http://domain.com to every place even if one already exists (so I would end up with something like this: <img src="http://domain.com/http://domain.com/images/image.png" alt="" />

How do I do this correctly?

Thanks,
Mike

Step 1. Remove http://domain.com/ from links and img src that have it so that all your urls become relative.
Step 2. Add http://domain.com/ just everywhere because now there is no way to get dupes.

That makes sense however what if there is a link to an external site? How would I handle that?

If you replace only http://domain.com/ then links to other domains will remain untouched.

That's a little bit more complicated.

I think you could do it like this:
1. Find the position of an occurence of the string <img src="http://
2. Go to that position and remove anything between " and the third / (including the third / )
3. str_replace("<img src=\"", "<img src=\"http://domain.com", $text);

You definitely need a combination of some different string functions.
