I need help, I have one regular expression but I don't understand.

I have this:

```
$string = '(54) (11) 4444 5555';
echo preg_replace("/\([^)]+\)/","",$string);

```

Output: `4444 5555`

But I need this output: `(11) 4444 5555`

And if I have (54(1(1))9) (11(2(3))) 4444 5555 
I need (11(2(3))) 4444 5555.

Without first parentheses.

Thx.
