Geoffrey, another way of saying this is that it's only the SCREEN
RENDERING that makes multiple whitespace characters APPEAR to be a
single space. If you view the source of your page I think you'll see
all your spaces intact.
Since the multiple spaces are really there in your string, you should
be able to operate on all of them, for example using string-array functions.
In your script:
$name = "Space 9";
* print "<p>Length: ".strlen($name);
printf("<p>Variable: %s",$name);
print "<p>Variable: '".$name."'";
echo "<p>Variable: ".$name;
* for($i=0; $i< strlen($name); $i++)
* print "<p>Character: ".$i."\"$name[$i]\"";
...the lines I've marked with an asterisk should reveal the true
length of the string, including all nine spaces, even though the
screen-print functions make it look like they've been consolidated
into one space.
