note 24800 added to function.intval

Note that you may substitute '\d' above by '[0-9]' for faster operations of PCRE regexps: - '[0-9]' is an explicit and constant character class that can be precompiled and reused. - '\d' is a conditional character class which is evaluated at runtime according to the current locale at invokation time with ctype_digit() function called to check each character; this disables some optimizations in the PCRE regexp compiler, as the following sets can't be precompiled. -- http://www.php.net/manual/en/function.intval.php http://master.php.net/manage/user-notes.php?action=edit+24800 http://master.php.net/manage/user-notes.php?action=delete+24800 http://master.php.net/manage/user-notes.php?action=reject+24800
