IMO it's not so much about cleaner code, than about performance.  Using
regexp's will shift all the hard work from PHP to C, which is much
faster.  Consider the code you've posted: it calls strpos(), substr(),
str_replace() et al. in a loop multiple times; for sure not the fastest
way of doing things.

A quick example, what can be accomplished with a simple regexp:

  >>> $str = 'Hello world, [key=value] [key2=value1] This is just a
  test. [key=value2]';
  >>> echo preg_replace('/\[key[0-9]*=value[0-9]*\]/', '', $str);
  Hello world,   This is just a test.

To fill the array of key/value pairs, you can start with:

  >>> preg_match_all('/\[(key[0-9]*)=(value[0-9]*)\]/', $str, $m);
  >>> var_dump($m)
