Question for php and regex gurus...

[BigBen]

I need to parse html for any image tags and store all of them in an array...

So if this is the html:

blah blah <img src="asdf.jpg" width="150"> more blah <img border="1" src="kasdf.gif">

The array should be:

$images[0] = asdf.jpg
$images[1] =kasdf.gif

Anybody know how I can do this?

I'm thinking something similar to this:

preg_match_all("|src\=\"?'?`?([[:alnum:]:?=&@/._+-]+)\"?'?`?|i", $string, $matches);

That works great. Thank you!

there are things other then images that use src= so you might want to be more explicit with that regex

Good point. It matches anything after src even if it's not in an img tag. Any ideas?

[Why]

preg_match_all("|src\=\"?'?`?([[:alnum:]:?=&@/._+-]+)+\.(gif|GIF|jpg|JPG)\"?'?`?|i", $string, $matches);

might work. but i didnt test it. it would only check for gifs and jpegs though.

Thanks for the help. What can I use to match just the image name from the string extracted from the first match?

Ie. How do I match just pic.jpg out of: src="http://example.com/images/pic.jpg"

I tried: preg_match("/\/.+?\.jpg/", $matches[1], $imagematch);
but that matches the longest string possible (//example.com/images/pic.jpg)

Thanks.

Thanks.

Maybe do a greedy match at first, just to get all the full & relative paths to the actual images grabbed out of the src tags. Then implode that $matched array into a string. Against that string, do a more refined match to just grab out the image names.

I'm having trouble doing that second part. My first regex will store the full path and I need to do a match against that string for the single image.
