如何在大写字母中回显文本?

问题描述:

我想知道如何在PHP中大写

I want to know how to capitalize in PHP

echo strtoupper('hello');

strtoupper 将大写整个字符串。

如果您只对首字母大写感兴趣,则可以使用 ucfirst

If you're only interested in capitalizing the first letter, you can use ucfirst:

echo ucfirst('hello!'); //Hello!

如果要大写字符串中每个单词的首字母,请使用 ucwords

If you want to capitalize the first letter of each word in a string, use ucwords:

echo ucwords('hello world!'); //Hello World!
