PHP : how to capitalize each word in a string

Question

I want to convert the first character of each word in a string to uppercase. What PHP function should I use?

e.g.

"hello brother, how are you?"

to

"Hello Brother, How Are You?"

Answer 1

You can use the ucwords() function. It converts the first character of each word in a string to uppercase. 

Here is an example:

<?php
$str = "hello brother, how are you?";
echo ucwords($str);
?>

The above code will return the following output:

Hello Brother, How Are You?
