No need to reinvent the wheel:

For email validation:

var_dump(filter_var(‘bob@example.com’, FILTER_VALIDATE_EMAIL));

#1 is a very very week way of validating email, this should not be implemented as it has many many flaws. (ALSO #1, #2, #3, #4, #5, #6 have been copied word for word out of CodeIgniter!! perhaps you should give some credit where credit is due). thanks.

Please, learn PHP the right way!

Your regular expression for email addresses is wrong. PHP has a very well builtin function to check if an email address is valid. Just have a look at the manual: http://www.php.net/manual/de/function.filter-var.php#refsect1-function.filter-var-examples

Your random string generator is ok for random strings, but never (!!!!) use it for passwords or if you need a safe random string / value. There are much better ways from a security point of view, just look at https://github.com/padraic/SecurityMultiTool/blob/master/library/SecurityMultiTool/Random/Generator.php for a good implementation.

And as Kristopher Wilson said, just use DateTime! http://php.net/DateTime

Most of these are crazy balls, but #9 is my favorite: How about just doing date(‘t’, strtotime(“$month/01/$year”)); ? or better yet: new DateTime(“$month/01/$year”)->format(‘t’); ?

Why write (! $some_boolean_expression) ? FALSE : TRUE when you could just use (! $some_boolean_expression)
