How to include EOL in this regex?

Question

I have this regex which can extract any substrings like {{string}} my regex: '/{{+(.*?)}}/'

and I need to modify it where it could extract strings like {{ something -enter-char-\r-OR\r\n- somthing }}

function replace_callback($matches)
{
    // just in case
    if ( !isset($matches[1]) || !is_string($matches[1]) ) throw new Exception(__FUNCTION__.': invalid $matches[1].');
    // detected var without brackets
    $var = $matches[1];

    // my program's processing on $var

    return $var;
}

$text = ' sdfhh fdfdf {{do:somecoolthings}} sdfggg';

echo preg_replace_callback(
    '/{{+(.*?)}}/',
    'replace_callback',
    $text
);

thanks in advance!

Edit: The people who see questions like this are programmers who don't have as much knowledge about regex, and this question asks a different goal than the other 2 "duplicate" questions, and I'm sure this post will become useful to someone.

final code:

function replace_callback($matches)
{
    // just in case
    if ( !isset($matches[1]) || !is_string($matches[1]) ) throw new Exception(__FUNCTION__.': invalid $matches[1].');
    // detected var without brackets
    $var = $matches[1];

    // my program's processing on $var

    return $var;
}

$text = ' sdfhh fdfdf {{
do:somecoolthings
}} sdfggg';

echo preg_replace_callback(
    '/{{(.*?)}}/s',
    'replace_callback',
    $text
);

The answer like this can easily be found on SO and in the Web, no need to post another one. — Wiktor Stribiżew, Jan 12 '17 at 08:37
should I delete this then? People could use this piece of code tho! — Mac A., Jan 12 '17 at 08:41
You do not have to delete the question, but you may. http://stackoverflow.com/questions/19316891/regular-expression-to-get-the-value-inside-double-curly-braces is easy to find, and the other one about the `s` modifier is also easy to find. — Wiktor Stribiżew, Jan 12 '17 at 08:43
It is not a rocket science to search for `regex spanning multiple lines` in Google. You'd get the answer quicker than writing all these comments. — Wiktor Stribiżew, Jan 12 '17 at 08:52
Thanks dude, I just found this awesome website about regex http://regexr.com/ perfect for learning — Mac A., Jan 17 '17 at 08:07
Yeah, it is popular. However, it only supports JS regex. If you want to test PCRE/Python regexes, too, use http://regex101.com — Wiktor Stribiżew, Jan 17 '17 at 08:08
