It looks to me that you want to replace all characters which are not a
number, a dot a space or a slash to "dot", is this true?? then you
might try:
$newstr = preg_replace("/[^\d.\/ ]+/", ".", $oldstr);
(untested)
I added a plus in the pattern /[^\d.\/ ]+/ to replace also something
like:
555:55;_@55_55 to 555.55.55.55 instead of 555.55...55.55
