PHP字符串转换第一个字符大写/小写

Question

I have two types of strings, 'hello', 'helloThere'.

What I want is to change them so they read like: 'Hello', 'Hello There' depending on the case.

What would be a good way fo doing this?

Thanks

Answer 1

you can use ucwords like everyone said... to add the space in helloThere you can do $with_space = preg_replace('/[A-Z]/'," $0",$string); then ucwords($with_space);
