[TASK] Use arrays in str_replace() calls

Multiple consecutive calls to str_replace can be replaced with a single
call if the subject is the same.

This will speed up the replacement and in some cases has the benefit of
being able to return or use the result of the str_replace directly without
creating an intermediate variable.

Bad:
$lala = 'something';
$lala = str_replace('so', 'the', $lala);
$lala = str_replace('me', ' ', $lala);
$lala = str_replace('thing', 'other', $lala);

Good:
$lala = str_replace(
  array('so', 'me', 'thing'),
  array('the', ' ', 'other'),
  'something'
);
