PHP: count uppercase words in string

Question

is there an easy way to count uppercase words within a string?

Answer 1

You could use a regular expression to find all uppercase words and count them:

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

The expression \b is a word boundary so it will only match whole uppercase words.

Answer 2

Shooting from the hip, but this (or something like it) should work:

function countUppercase($string) {
     return preg_match_all(/\b[A-Z][A-Za-z0-9]+\b/, $string)
}

countUppercase("Hello good Sir"); // 2
