Description:
------------
A function to trim / merge whitespace inside a string (so not just at the begin, end) would be nice to have and especially useful for single-line input.

It should replace all sequences of 1 or more whitespace characters by a single space.

Test script:
---------------
echo trim_all('A  B \t C \n D');

Expected result:
----------------
A B C D

Actual result:
--------------
A  B \t C
 D

what's the problem with
```
preg_replace('/\s+/', ' ', $str);
```

Readability / teachability maybe. http://php.net/trim got a dedicated function / name as well..

Adding yet another string function to ext/standard is certainly
not uncontroversial (at least I do not see sufficient benefit in
this case) – please, feel free to start the RFC process[1].  I'm
suspending this ticket for the time being.
