ucwords method in php

What will be the output of [ ucwords(INTERVIEWHOME)?
Answer:
The ucwords function makes every first letter of a word capital. It transforms every first letter of a word to a uppercase character.

However, in this example the rest of the letters are also capital.
Hence the output of ucwords(INTERVIEWHOME) will be
- INTERVIEWHOME

To convert the given string to "INTERVIEWHOME", you can first use strtolower to convert it to all lower case characters and then use ucwords on it.
