Apostrophes

Can anyone please help me with the following problem?

I have a user whose name ends with an apostrophe (i.e Bonet'). I want to make the name with an s like this (for ownership) Bonet's instead of Bonet''s with 2 apostrophes. I am using $userinfo[username] to get the name and if I use an 's for ownership on all other names it appears fine. I need to have it not add an apostrophe after the name if one is already there, just the s, but still keep the 's for all other names. I know it sounds confusing. I'm not sure how to pull the information out of the username variable to do this. Can anybody help?

em you could use a regexp but simpliest way is

if(substr($userinfo['username'], -1) == '\\'') {
$userinfo['username'] .= 's';
} else {
$userinfo['username'] .= '\\'s';
}

Scott, that works perfect. As a matter of fact, it works too perfect. Is there a way I can use a variable after the users name (like $s) instead so I can just use it where I need it and not have it show up where I don't?

BTW: What is a regexp? Just curious.

Here's what I came up with. It seems to work. Is it right? And thank you, Scott.

if(substr($userinfo['username'], -1) == '\\'') {
$a= 's';
} else {
$a= '\\'s';
}

could use

if (preg_match ("(\\'$)", $userinfo['username'])) {
$a .= 's';
} else {
$a .= '\\'s';
}

Ok, one last question, please. And thank you for all of the help on this. I really appreciate it.

Is there a way to do it globally for any username variable (i.e. $bbuserinfo[username] and $userinfo[username] and $post[username]) instead of having to do it individually in each area and with each different username variable?

And thank you for the link, Chen. I will check it out.

you could just make a function

function doapostrophe($username) {
if (preg_match ("(\\'$)", $username)) {
$username .= 's';
} else {
$username .= '\\'s';
}
return $username;
}

and when you need to just use
$userinfo['username'] = doapostrophe($userinfo['username']);

something like that?

[Boofo]

That sounds like what I am looking for. But would there be a way to make it with the $a variable so I could just add the $a where I needed it instead of having to do the doapostrophe all over the site? And I could put this anywhere in the functions.php and it would work site wide, right? Or do I need to put it a certain place in there?

You could just use

$userinfo['usernames'] = doapostrophe($userinfo['username']);

and just user $userinfo['usernames'] where you want it with the s at the end.

Correct anywhere in functions.php
