Answer 1

来自苏格兰的麦克唐纳先生更喜欢这样大写他的名字，而来自爱尔兰的麦克唐纳先生更喜欢这样。 如果不事先知道你指的是哪位先生，就很难知道哪个是"正确的"，这需要比文件中的单词更多的上下文。

此外，BBC

（或者说是BBC？）已经开始拼写一些名字，如NASA和Nato。 它震撼了我;我非常不喜欢它。 但这就是他们现在所做的。 acrynom（或有些人喜欢称之为"首字母缩写"）什么时候成为一个独立的词？

Answer 2

这有点黑客，您可以存储要保持大写的首字母缩略词列表，然后将字符串中的单词与$exceptions列表进行比较。虽然乔纳森是正确的，但如果它命名你的工作而不是首字母缩略词，那么这个解决方案是没有用的。但显然，如果来自苏格兰的麦克唐纳先生处于正确的情况，那么它就不会改变。

$exceptions = array("to", "a", "the", "of", "by", "and","on","those","with",
                    "NASA","FBI","BBC","IBM","TV");
$string = "While McBeth and Mr MacDonald from Scotland
was using her IBM computer to watch a ripped tv show from the BBC,
she was being watched by the FBI, Those little rascals were
using a NASA satellite to spy on her.";
echo titleCase($string, $exceptions);
