How to remove whitespace via php preg_replace between all brackets in text

I have the The similar text:

"Eat [ 12 ] my [ 15] shorts [ 20 ]"

And I would like to remove whitespace from all brackets in string.

I tried something like:

$str = 'Eat [ 12 ] my [ 15]  shorts [ 20 ]';
$str = preg_replace_callback("~\([^\)]*)\)~", function($s) {
    return str_replace(" ", "", "($s[1])");
}, $str);
echo $str;

But still without succes.

Could somebody tell my, how to do this right way please?

Many thanks for any help.

If you know, that there is going to be only one white space, you can use simple str_replace. That will be a lot faster then preg_replace:

$str = str_replace( array( '[ ', ' ]' ), array( '[', ']' ), $str );

Try this:

$str = 'Eat [ 12 ] my [ 15]  shorts [ 20 ]';
$str = preg_replace('#\[\s+#', '[', $str);
$str = preg_replace('#\s+\]#', ']', $str);
