An alternative:
$str = preg_replace('/[\\!\\?\\.]*/', ' ', $str);
And usual rant #37:
\ and ' are special characters inside of '' and you really SHOULD
escape them, even though PHP will let you get away with not doing it,
yea, even unto it being a "documented feature" that \x will turn into
\x so long as x is not \ or '
I also think str_replace() might be more appropriate, but would be
cautious about claims on speed for str_replace versus preg_replace,
if, for example, the array() of characters to be replaced was HUGE...
You'll have to benchmark on your own gear *IF* it matters to you,
which I doubt.
