Question

I need a help with this regexp..

using

/\{block:(Posts|Photos|Videos)(\s\[.*?\])?\}(\s?[^\"]+\s?)\{\/block\}/U

i get {block:Posts}abcdef{/block} from this:

<div>
 {block:Posts [a=1, b=2]}
  abcdef
 {/block}
</div>

But if my text is like this:

<div>
 {block:Posts [a=1, b=2]}
  {block:Text}
   abcdef
  {/block}
 {/block}
</div>

i get {block:Posts}{block:Text}abcdef{/block} because it’s based on the first {/block} found in text.

A simple way to avoid this is using {/block:Posts} to close the block, but how can I do that since the opening block tag is optional (Posts|Photos|Videos)? If I open the block with Photos I must be sure it has to be closed with {/block:Photos}.

Using /\{block:(Posts|Photos|Videos)(\s\[.*?\])?\}(\s?[^\"]+\s?)\{\/block\:(Posts|Photos|Videos)\}/U of course doesn’t help…

Can anyone please help me?

Thanks!!

PS
Is it possible, modifying the regex above, to get the optional parameters a and b as an array?

There might be an overall better solution for your problem, but you can use a backreference in this case, as (Posts|Photos|Videos) is capture group already:

\{\/block:\1\}
