Need help with regex

[aditan22]

Supposed I have a string like this:

bla bla {strong} bla bla bla {bold} bla bla

How to get {strong} and {bold} using regex? I've already tried:

/\{.*\}/

but the result is:

{strong} bla bla bla {bold}

/\{.*?\}/

[aditan22]

ah okay, thanks... lol, why I missed that one

actually I'm working for something like:

bla bla {{strong} bla} bla bla {bold} bla bla

so it's nested, and I need this result:

{{strong} bla}
{strong}
{bold}

can I only use regex? I'm thinking to create recursive function

Simple iteration would be enough

$s = 'bla bla {{stro{ng}} bla} bla bla {b{o}ld}bla bla';
$re = '/\{([^{}]*)\}/e';

while(preg_match($re, $s))
    $s = preg_replace($re, '$matches[]="$1"', $s);

print_r($matches);

That's cool simple solution stereofrog!
Darn... I'm too late seeing your reply here, I have already made a recursive function, it's more complicated lol.
Btw, I want to have '\{' and '\}' not being translated, how to tell regex to ignore that?

For example:

bla \{bla\} {{strong} bla} bla bla {bold} bla bla

and the result is the same with above while '\{bla\}' is not selected.

thanks.

To handle escapes, change bounding \{'s to (?<!\\\\)\{ , inner group should be something like ((\\\\.|[^{}])*).
