Php find string with regex

Question

I've read multiple tutorials on regex but it just won't stick in my head. I can never get my patterns to work. Hope someone can help.

I have a php variable ($content) where I need to find a certain pattern that looks like this

[gallery::name/of/the/folder/]

I would like to search:

- starting with "[gallery::" - any other character (variable length) - ending with "]" 

So far, in PHP I have:

   preg_match('/\[gallery\:/', $content, $matches, PREG_OFFSET_CAPTURE); 

I can find [gallery: but that's it. I would like to be able to find the rest (:name/of/the/folder/])

Any help is appreciated! Thanks!

Answer 1

Try capturing it:

preg_match("/\[gallery::(.*?)]/", $content, $m); 

Now $m is an array:

0 => [gallery::/name/of/the/folder/] 1 => /name/of/the/folder/ 

Answer 2

change your regex to

'/\[gallery::([A-Za-z\/]+)\]/' 

Since I put the folder/path part in parenthesis, you should get a capture group out of it.
