I use the function getValue to query the database and get the value of the variable. This function is pretty slick; now, PHP just needs to support callbacks that aren’t created as strings and we’ll be all set.

CREATE ROLE db_executor GRANT EXECUTE TO db_executor EXEC SP_ADDROLEMEMBER 'db_executor', 'username'

The above:

Creates the role db_executor Grants execute permissions to the role Adds the desired user to the role

Because roles exist within a database, this should be done in the context of the database desiring the programmability required.

trait HelloWorld { public function sayHello() { echo 'Hello '; }   public function sayWorld() { echo 'World!'; } }   class MyClass { use HelloWorld; public function sayHelloWorld() { $this->sayhello(); $this->sayWorld(); } }   $h = new MyClass(); $h->sayHelloWorld(); // outputs "Hello World!"

In implementing traits, the keywords trait and insteadof were added to PHP. Usage of trait is outlined above. The PHP keyword insteadof is used for conflict resolution. Here’s an example of how to use insteadof:

trait A { public function smallTalk() { echo 'a'; } public function bigTalk() { echo 'A'; } }   trait B { public function smallTalk() { echo 'b'; } public function bigTalk() { echo 'B'; } }   class Talker { use A, B { B::smallTalk insteadof A; A::bigTalk insteadof B; } }   class Aliased_Talker { use A, B { B::smallTalk insteadof A; A::bigTalk insteadof B; B::bigTalk as talk; } }

<? $res = "";   $f = new NumberFormatter("en", NumberFormatter::SPELLOUT);   for($i = 1; $i format($i)); if($i > 100 && $i % 100 != 0) { $res .= 'and'; } } echo strlen($res)."\n";

My first submission was incorrect and I quickly figured out it was because the NumberFormatter class was missing the “and” after the hundreds. I simply added that at the end since we’re only looking for a count and came up with the correct result. Installing the NumberFormatter class in Debian squeeze was pretty easy. I simply had to install the PHP5 international compatibility package: sudo apt-get instal php5-intl
