Problem evaluating code with {}

[silviuchingaru]

I have the folowing subject:

[code]<table border="1" class="dashed">
 <tr>
   <th class="title">{title}</th>
 </tr>
<!--loopStartLink-->
 <tr>
   <td>{link}</td>
 </tr>
<!--loopEndLink-->
</table>[/code]

and the folowing preg_match shoud change an tag like {link} only if array $tags['link'] is set, else it should leave the tag unchanged:

[code]preg_replace("/\{(\w+)\}/e",'!$tags["\\1"]?"{\\1}":$tags["\\1"]',$output);[/code]

it works perfect without the } like this:

[code]preg_replace("/\{(\w+)\}/e",'!$tags["\\1"]?"{\\1":$tags["\\1"]',$output);[/code]

and writes only {link but I have to write full tag like {link}.

What is the problem? Why when I add } it doesn't work. Is there a way to escape } (I tried with \} but doesn't work).

Please help!
Thank's!

I'm not sure what you're trying to say; your first regex works fine. What version of PHP are you running?
