PHP-每个单词的首字母大写期望某些单词

问题描述：

我有一堆这样的字符串：

I have a batch of strings like so:

tHe iPad hAS gONE ouT of STOCK
PoWER uP YOur iPhone
wHAT moDEL is YOUR aPPLE iPHOne

我要大写每个单词的第一个字符其余字符均小写- iPhone 或 iPad 的引用除外。如：

I want to capitalise the first character of each word and have the remaining characters lowercase - except any references of iPhone or iPad. As in:

通过使用：

ucwords(strtolower($string));

这可以满足大部分需要，但显然也可以在 iPad上完成和 iPhone ：

This can do most of what is needed but obviously also does it on iPadand iPhone:

The Ipad Has Gone Out Of Stock
Power Up Your Iphone
What Model Is Your Apple Iphone

如何实现以下目标：

The iPad Has Gone Out Of Stock
Power Up Your iPhone
What Model Is Your Apple iPhone

答

为此 str_replace 。如果对前两个参数使用数组，则可以定义一组单词和替换：

You can use str_replace for this. If you use arrays for the first two arguments, you can define a set of words and replacements:

echo str_replace(['Ipad', 'Iphone'], ['iPad', 'iPhone'], ucwords(strtolower($string)));

来自文档：

如果搜索和替换是数组，则str_replace（）从每个数组中获取一个值，并使用它们对主题进行搜索和替换。

If search and replace are arrays, then str_replace() takes a value from each array and uses them to search and replace on subject.
