[SOLVED] Regex [img] tags

[chocopi]

I was just flicking through the tutorials on phpfreaks and came across Akitchen's phpBB tut. The pattern he uses for the img tags is:

 

"|\[img\](http://.*?)\[/img\]|s"

 

However, anything that starts with http:// and is within img tags will statisfy the pattern

 

So basically the whole point of this message is can someone help me so that this pattern will only be true if it ends in an image extension. I have got a feeling this means i will have to change most of the pattern

 

Anyways, Many Thanks

try this

 

"|\[img\](http://.*?(jpg|bmp|gif|jpeg))\[/img\]|s"

 

 

PS wrong section

 

should be in RegEx

[chocopi]

no that doesnt work

 

btw im using this string:

"hello your image is [img=http://www.google.com/image.gif] some extra text"

 

And yea I know it should be in regex but they are just quite a bit slower at responses, and seeing as it is not major regex didn't think it would be too bad posting it here.

Cheers, thats sorted it !

 

Just out of intrest do you know any good regex tutorials ? As I currently have the php pattern syntax and some other google ones, but I don't think they are that useful to me.

 

Anyway, Thanks
