preg_replace multiple strings between brackets (php/regex)

Question

I have string

[test](test\\-test\\-abc) abcde\\-

I would like to have

[test](test-test-abc) abcde\\-

I need to replace \\- with - with regex/preg_replace. Need to replace string only between parenthesis. I found a solution but it only replaces first occurance.

$result = preg_replace("/(\[.*?\])(\(.*?)(\\\\-)(.*?\))/", '$1$2-$4', $str);

Those aren't brackets: those are parenthesis.

You can use preg_replace_callback:

$str = '[test](test\\\\-test\\\\-abc) abcde\\\\-';
$txt = preg_replace_callback('~\([^)]+\)~',
    function ($m) { return str_replace('\\\\-', '-', $m[0]); }, $str);
echo $txt;
//=> [test](test-test-abc) abcde\\-
