Question

I’m looking for elegant regular expression to clean brackets with content looks like file name.

[Nibh justo] elit Nulla [link.pdf]  auctor ipsum molestie (link.pdf) 
Condimentum euismod non [link.xls](link.xls) [link.doc](link.doc) tempus 
In [Curabitur] et

The result should be:

Nibh justo elit Nulla auctor ipsum molestie Condimentum euismod 
non tempus In Curabitur et

I trust there must be a short way do that.
(File means simply – dot included. No sentences check is necessary.)

thank for help

Something like this ?

$str = '[Nibh justo] elit Nulla [link.pdf]  auctor ipsum molestie (link.pdf) 
Condimentum euismod non [link.xls](link.xls) [link.doc](link.doc) tempus In 
[Curabitur] and other [./beta/link.pfd]';

$str = preg_replace('`(\(|\[)[\w/\.-]+\.[a-z]+(\)|\])`i', '', $str);
$str = str_replace(array('[', ']'), '', $str);

echo $str;

Result is :

Nibh justo elit Nulla auctor ipsum molestie Condimentum euismod 
non tempus In Curabitur and other
