How to echo text in capital letters?

Question

I want to know how to use in PHP

Answer 1

echo strtoupper('hello');

strtoupper will use the entire string.

If you are only interested in writing the first letter, you can use ucfirst :

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

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

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

Answer 2

Function strtoupper()is what you are looking for.
