Question

Is there a function or way on how to get the CAPS words on a sentence or string?
Example: $str = "ABOUT US who we are"
how am i able to identify and get the capitalized words "ABOUT US"and separate it to small letter words "who we are"? So that the output would be $str1 = "ABOUT US" and $str2 = "who we are"… thanks!

Answer 1

You can use a regular expression for it:

preg_match_all('/\b([A-Z]+)\b/', $str, $matches);

To match the lowercase words, use this:

preg_match_all('/\b([a-z]+)\b/', $str, $matches2);

Then you can use functions such as implode() to build the strings.
