问题
I am having trouble with the capitalization of names using PHP. There are some names that have 2 capital letters in them (ex: McCall). When storing a users name that registers for our website, we run the following code:
$name = ucwords(strtolower(trim($_SESSION['last_name']))) ;
What this does is change 'mccall' to 'Mccall'. What we need is a way to check if the first 2 letters begin with 'Mc' and if so, the 3rd letter will be capitalized as well changing the name to 'McCall'.
Any help is greatly appreciated.
回答1:
$name = 'mccall';
$name = ucwords(strtolower(trim($name))) ;
if (strpos($name, 'Mc') === 0) {
$name = 'Mc' . ucwords(substr($name, 2, strlen($name)));
}
echo $name; // McCall

Here's a solution that will just catch Mc, if that's really all you're interested in:
function capitalizeLastName($name) {
$result = ucwords(strtolower(trim($_SESSION['last_name'])));
if(substr($result, 0, 2) === 'Mc') {
$result[2] = strtoupper($result[2]); // Yes, this works in PHP!
}
return $result;
}

Just FYI, I have a REALLY nice function for capitalizing a lot more than just names. It also does titles, phrases, etc...
It takes a string parameter and a boolean. The bool is TRUE if you're capitalizing a name, and FALSE or nothing if it's a title, phrase, etc...
Use is as simple as:
capitalize('mccall', TRUE); // result 'McCall'
capitalize('merry christmas and happy holidays!'); // result 'Merry Christmas and Happy Holidays!'
capitalize('jd mckinstry', TRUE); // result 'JD McKinstry'
The fun ction!
function capitalize($str, $is_name=FALSE) {
$str = trim(stripcslashes($str));
// exceptions to standard case conversion
if ($is_name) {
$all_uppercase = '';//'Aj|Jd';
$all_lowercase = 'De La|De Las|Der|Van De|Van Der|Vit De|Von|Or|And|Van ';
}
else { // addresses, essay titles ... and anything else
$all_uppercase = 'Po|Rr|Se|Sw|Ne|Nw';
$all_lowercase = 'A|And|As|By|In|Of|Or|To';
}
$prefixes = 'Mc';
$suffixes = "'S";
// captialize all first letters
$str = preg_replace('/\\b(\\w)/e', 'strtoupper("$1")', strtolower(trim($str)));
if ($all_uppercase) { // capitalize acronymns and initialisms e.g. PHP
$str = preg_replace("/\\b($all_uppercase)\\b/e", 'strtoupper("$1")', $str);
}
if ($is_name) {
if (strpos($str, " ") !== FALSE) {
$ara = explode(" ", $str);
foreach ($ara as $k => $v) {
if ($k != count($ara)-1 && !preg_match("/[aeiouyAEIOUY]/", $v)) $ara[$k] = strtoupper($v);
}
$str = implode(" ", $ara);
}
elseif (!preg_match("/[aeiouy]/", $str)) {
$str = strtoupper($str);
}
}
if ($all_lowercase) { // decapitalize short words e.g. and
if ($is_name) { // all occurences will be changed to lowercase
$str = preg_replace("/\\b($all_lowercase)\\b/e", 'strtolower("$1")', $str);
}
else { // first and last word will not be changed to lower case (i.e. titles)
$str = preg_replace("/(?<=\\W)($all_lowercase)(?=\\W)/e", 'strtolower("$1")', $str);
}
}
if ($prefixes) { // capitalize letter after certain name prefixes e.g 'Mc'
$str = preg_replace("/\\b($prefixes)(\\w)/e", '"$1".strtoupper("$2")', $str);
}
if ($suffixes) { // decapitalize certain word suffixes e.g. 's
$str = preg_replace("/(\\w)($suffixes)\\b/e", '"$1".strtolower("$2")', $str);
}
// Mac Exceptions
if (strpos($str, "Macd") === FALSE || strpos($str, "Macv") === FALSE) {
$str = preg_replace("/Macd/", 'MacD', $str);
$str = preg_replace("/Macv/", 'MacV', $str);
}
return trim(stripcslashes($str));
}
As some of you might notice, this was originally taken from the PHP site, but I've since nurtured it and matured it into a much more useful and "intelligent" method!

I found this answer as I was searching on the function found in the PHP manual, as answerd by SpYk3HH.
The preg_replace has been deprecated as correctly noticed by Michelangelo. To save others some time here the renewed function.
Plus some additions to support Dutch names:
<?php
function capitalize($str, $is_name = FALSE) {
$mylist = "S|‘s|‘t|A|Aan|Aan ‘t|Aan De|Aan Den|Aan Der|Aan Het|Aan T|Af|Al|Am|"
