How to find (and replace) words with capital letters from a string?

$string = "WORD is the first HEJOU is the Second BOOM is the Third";
$sring = str_replce('???', '???<br>', $string);
echo $string; // <br>WORD is the first <br>HEJOU is the Second <br>BOOM is the Third

Well the illustration speaks for itself. I want to select all words with capital letters (not words that start with capital letter) and replace with something in front of it. Any ideas?

str_replace just replace specific string to other specific one. You may use preg_replace

print preg_replace('~\b[A-Z]+\b~','<br>\\0',$string);

$string = "WORD is the first HEJOU is the Second BOOM is the Third";
$string = preg_replace("#\b([A-Z]+)\b#", "<br>\\1", $string);
echo $string;

OUTOUT
<br>WORD is the first <br>HEJOU is the Second <br>BOOM is the Third

The regular expression being used says: 

\b - Match a word boundary, zero width
[A-Z]+ - Match any combination of capital letters 
\b - Match another word boundary
([A-Z]+) - Capture the word for use in the replacement

Then, in the replacement

\\1, replace with the captured group.
