Initial capitalization of strings in PHP

I've got someone's first name in a string, and I'd like to do two things:

1. Make sure that it's capitalized properly: Joe, not JOE, joe, JOe, jOe, etc.
2. Strip any titles (and the titles may be in any permutation of lower/uppercase letters, and may or may not be punctuated: Dr, Mr, Mrs, Ms, and all the variations of those.

Are there functions I can use to do this?

for 1) are you aware of the functions ucfirst() and ucwords() in php?

for 2) I will leave that for the regexp experts...
1. To make sure that only the first letter of the word is capitalized, first lower-case the entire word:

$name = strtolower($name);

Then capitalize the first letter:

$name = ucfirst($name);

Or, to do it all at once:

$name = ucfirst(strtolower($name));

2. You should make an array of all the titles that you wish to replace:

$arrTitles = array('Mr', 'Mr.', 'Mrs', 'Mrs.', 'Dr', ...);

Then, use str_replace to remove them:

$name = str_replace($arrTitles, '', $name);

If you're going to do it by an array you should probably have the titles with a dot in them before the titles without the dot... WHY? Case of Mr. Rodgers Well if you replace Mr and then go on to check for Mr., the latter will not be found and you will be stuck with a period before the persons name.
Good catch, Brian. You are exactly right.
