From the preg_replace documentation on php.net :

substitute might have referrals of the kind \ n or (given that PHP 4.0.4 ) $n,. with the last kind being the. favored one. Every such reference. will certainly be changed by the message recorded. by the n'th parenthesized pattern.

See Flubba's instance.

You require to place the pattern in parentheses /([A-Z])/, similar to this :

preg_replace("/([A-Z])/", "<span class=\"initial\">$1</span>", $str)
