我想标准化用户提供的字符串。我希望名称的第一个字母大写，如果他们输入了两个姓氏，则将名字和第二个名字大写。例如，如果有人输入：
marriedname maidenname
如果有两个以上的名称，它会将其转换为Marriedname Maidenname等等。
另一种情况是某人的名字中有撇号。如果有人进入：
o'connell
这需要转换为O'Connell.
我正在使用：
ucfirst(strtolower($last_name));
但是，正如您所知，这不适用于所有场景。
这将大写所有单词的第一个字母，以及撇号后的字母。它将使所有其他字母小写。它应该适合你：
str_replace('\' ', '\'', ucwords(str_replace('\'', '\' ', strtolower($last_name))));
你可以试试这个
<?php echo ucwords(strtolower('Dhaka, JAMALPUR, sarishabari')) ?>
结果是：Dhaka, Jamalpur, Sarishabari
这些都不是 UTF8 友好的，所以这是一个完美无缺的（到目前为止）
function titleCase($string, $delimiters = array(" ", "-", ".", "'", "O'", "Mc"), $exceptions = array("and", "to", "of", "das", "dos", "I", "II", "III", "IV", "V", "VI"))
{
/*
* Exceptions in lower case are words you don't want converted
* Exceptions all in upper case are any words you don't want converted to title case
* but should be converted to upper case, e.g.:
* king henry viii or king henry Viii should be King Henry VIII
*/
$string = mb_convert_case($string, MB_CASE_TITLE, "UTF-8");
foreach ($delimiters as $dlnr => $delimiter) {
$words = explode($delimiter, $string);
$newwords = array();
foreach ($words as $wordnr => $word) {
if (in_array(mb_strtoupper($word, "UTF-8"), $exceptions)) {
// check exceptions list for any words that should be in upper case
$word = mb_strtoupper($word, "UTF-8");
} elseif (in_array(mb_strtolower($word, "UTF-8"), $exceptions)) {
// check exceptions list for any words that should be in upper case
$word = mb_strtolower($word, "UTF-8");
} elseif (!in_array($word, $exceptions)) {
// convert to uppercase (non-utf8 only)
$word = ucfirst($word);
}
array_push($newwords, $word);
}
$string = join($delimiter, $newwords);
}//foreach
return $string;
}
用法：
$s = 'SÃO JOÃO DOS SANTOS';
$v = titleCase($s); // 'São João dos Santos'
使用这个内置函数：
ucwords('string');
我不相信会有一个涵盖所有场景的好答案。PHP.net 论坛ucwords有相当多的讨论，但似乎没有一个能解决所有问题。我建议您使用大写字母或单独保留用户的输入进行标准化。
这是对主要问题的更简单和更直接的答案。下面的函数模仿了 PHP 方法。以防万一 PHP 将来使用它们的命名空间扩展它，首先检查一个测试。我正在为我的 wordpress 安装中的任何语言使用这种防水。
$str = mb_ucfirst($str, 'UTF-8', true);
这使第一个字母大写，所有其他小写字母与 Q 一样。如果第三个 arg 设置为 false（默认值），则不会操纵字符串的其余部分。
// Extends PHP
if (!function_exists('mb_ucfirst')) {
function mb_ucfirst($str, $encoding = "UTF-8", $lower_str_end = false) {
$first_letter = mb_strtoupper(mb_substr($str, 0, 1, $encoding), $encoding);
$str_end = "";
if ($lower_str_end) {
$str_end = mb_strtolower(mb_substr($str, 1, mb_strlen($str, $encoding), $encoding), $encoding);
} else {
$str_end = mb_substr($str, 1, mb_strlen($str, $encoding), $encoding);
}
$str = $first_letter . $str_end;
return $str;
}
}
您可以preg_replace与e标志一起使用（执行 php 函数）：
function processReplacement($one, $two)
{
return $one . strtoupper($two);
}
$name = "bob o'conner";
$name = preg_replace("/(^|[^a-zA-Z])([a-z])/e","processReplacement('$1', '$2')", $name);
var_dump($name); // output "Bob O'Conner"
也许正则表达式模式可以改进，但我所做的是：
$1是行首或任何非字母字符。$2是任何小写字母字符processReplacement()然后我们用简单函数的结果替换这两个。
如果您有 PHP 5.3，那么创建processReplacement()一个匿名函数可能是值得的。
这是我对 PHP 中拉丁名称大写的高度过度设计但非常包罗万象的解决方案。它将解决您所有的大小写问题。他们全部。

玩一玩。
首先转换为标题大小写，然后找到第一个撇号和大写的 NEXT 字符。您将需要添加许多检查，以确保撇号后有一个字符，并且此代码仅适用于一个撇号。例如“玛丽·奥卡拉汉·奥康奈尔”。
$str = mb_convert_case($str, MB_CASE_TITLE, "UTF-8");
$pos = strpos($str, "'");
if ($pos != FALSE)
{
$str[$pos+1] = strtoupper($str[$pos+1]);
}
如果您使用的是 WordPress，请使用：
function archive_title() {
$title = '<h1>' . ucwords( single_tag_title( '', false ) ) . '</h1>';
}
