to running strtoupper() on the string literal '\\2' which after it has been
capitalized will be '\\2'.
if you *really* want to use preg_replace():
echo preg_replace("/(^)(.)(.*\$)/e", "\"\\1\" . strtoupper(\"\\2\") . \"\\3\"", "yikes!"),
"\n";
notice the 'e' modifier on the regexp - it causes the replace string to be treated as a string of php
code that is autoamtically evaluated - checvk the manual for more info.
(I used double quotes only so that I could test the code on the cmdline using 'php -r')
...BUT I suggest you try this function instead: ucfirst()
