Hi All,
I want to cut down the name of the user to 10 characters so it will
fit to the picture of the user.
At this moment I use $firstnameCut = substr($firstname, 0, 10);
However sometimes the name is like:
Johannes Paul.
with my code it will show: Johannes P
How can I change this so if the second or third name doesn't fit
within the 10 characters
it will not be shown at all?
Regards
Marco

a) Count back from the end of the string to find the location of the last
space, and truncate the string to that point.
b) split the name string into an array, and add bits of the string
together with spaces until the next added bit would exceed your maximum
length.
There may be other ways.

This is not a PHP answer per se. Give some though to using the first X
characters from the first name and the first Y characters from the last
name. It may resolve some of your dilemma. It has a favorable side
effect of producing a decently unique set of characters (most of the time).

What will you do if the *first* name doesn't fit within 10 characters? In
English-speaking countries, "Christopher" (11 characters) is a fairly common
given name for men. I have a Polish friend whose given name is Wlodzimierz
(also 11 characters). In some languages (e.g. Thai or Malayalam) names can be
*much* longer than that.
Perhaps this will produce what you want:
a) if the 11th character is a space, truncate at 10 characters and quit
b) if there are no spaces in the first 10 characters, truncate at 10 and quit
c) if neither a) nor b) is true, search backward from the 10th character and
truncate at the first space you find.

How about somthing like this:
$x = strpos($Name, " ");
if ($x > 10) { $x = 10; }
$FirstName = substr($Name, 0, $x);
This might accomplish close to what you are looking for. Tweat this
and it should work OK for you.
Good luck.

Hello Marco,
I like using ... to show the visitor that something is cutted away.
eg:
Marco --> Marco
Johannes Paul -> Johannes...
But that works better for longer strings. If you only want 10
characters, the 3 ... take up too much space I expect.
Also, make sure you give your image a title="Johannes Paul" and
alt="Johannes Paul" so everybody can easily find the full name by
hovering over the image.
Regards,

And, an 'interesting' side effect of sometimes producing fairly
vulgar character strings...
