You could use preg_split or split with a limit of 1 set but it's just as easy to use a match.

CODE

<?

$text = 'this is some 1.5 text. this is some more. and so is this.';

# matches '<dot><space>' so that it should split at the
# end of a sentence, not within a number such as 1.5
if(preg_match('/(.*?\. )(.*)/',$text ,$match)) {
   array_shift($match); # remove first match because it's the whole string.
   print_r($match); # $match[0] is before <dot><space> $match[1] is after.
} else {
   print $text;
}

?>

Why with the split function? The code I gave does exactly what you asked for.

You said at the first '.' not every '.' so I would suggest the above method to split at the first '.'. You could use:
CODE

$text_split = split('[.]', $text, 1);


but then it will split when it sees a dot regardless of if it's contained within a number or not, this could lead to unexpected results.

If you want to split at all dots then all you need to do is remove remove the limit. The manual should spell out any other questions regarding the split() or preg_split() functions.
