PHP - Need to fill array from text

Question

I need to fill an array from all text, within a string that begins with [ and ends with ].

For Example:

here is some text [to do] and something else [/find] for the way this works is [object] and [tada]

This should return an array like so:

array('[to do]', '[/find]', '[object]', '[tada]');

How can I do this quickly? And in the same order that's in within the text?

There can be any characters at all within the square brackets. I just need to grab them all, plus both brackets.

In the PHP Language. Sorry bout that.

$subject = "here is some text [to do] and something else [/find] for the way this works is [object] and [tada]";
preg_match_all("/\[[^\[\]]+\]/", $subject, $out);
var_dump($out[0]);

You can use preg_match_all.

preg_match_all('/\[(.*?)\]/', $text_to_filter, $array);

$array will contain your matches.

It won't work with nested square brackets, though.
