ucfirstletter()

Description

Returns a string with the first LETTER of $string capitalized.
Compare with ucfirst($string) which returns a string with first CHAR of $string capitalized:
ucfirstletter("abc") / ucfirstletter("%abc") returns "Abc" / "%Abc"
ucfirst("abc") / ucfirst("%abc") returns "Abc" / "%abc"

Search for the first letter ([a-zA-Z]), which may or may not be followed by other characters (.).
Replaces the found substring ('$0') with the same substring but now with the first character capitalized, using ucfirst().
Note the /e modifier: If this modifier is set, preg_replace() does normal substitution of backreferences in the replacement
string, evaluates it as PHP code, and uses the result for replacing the search string.
