PHP 5 provides a way for objects to be defined so it is possible to iterate through a list of items, with, for example a foreach statement. By default, all visible properties will be used for the iteration.
Example #1 Simple Object Iteration
<?php
class MyClass
{
   public $ var1 = âvalue 1â²;
   public $ var2 = âvalue 2â²;
   public $ var3 = âvalue 3â²;
   protected $ protected = âprotected varâ;
   private  $ private  = âprivate varâ;
   function iterateVisible() {
      echo âMyClass::iterateVisible:\nâ;
      foreach($ this as $ key => $ value) {
          print â$ key => $ value\nâ;
      }
   }
}
$ class = new MyClass();
foreach($ class as $ key => $ value) {
   print â$ key => $ value\nâ;
}
echo â\nâ;
$ class->iterateVisible();
?>
The above example will output:
var1 => value 1
var2 => value 2
var3 => value 3
MyClass::iterateVisible:
var1 => value 1
var2 => value 2
var3 => value 3
protected => protected var
private => private var
Canât get a decent cell signal in your living room? I know the feeling. Thatâs why more and more carriers are offering femtocells: compact, antenna-equipped boxes that use your home broadband network to boost cell reception. Clever ideaâalthough youâll pay extra for the privilege, of course.
Sprint has had its own femtocell deviceâthe Airaveâon sale for more than a year now, while Verizon Wireless announced its own femtocell service this week. That leaves AT&T, which is rumored to have a femtocell product in the works, and T-Mobile, which offers something a little different: Unlimited HotSpot Calling (formerly known as T-Mobile HotSpot @Home).
Helio may have been gobbled up by Virgin Mobile last summer, but the brand name lives on, as evinced by the newâif only modestly revampedâOcean 2 QWERTY slider. Is the latest Ocean worth the $ 70 premium over the already robust original?
Set to go on sale next Thursday (Feb. 12) for $ 149 with a two-year contract (post-paid, not pre-paid as with Virgin Mobileâs other handsets), the Ocean 2 has been whispered about for monthsâindeed, the first fuzzy photos appeared on the Web last May, while a series of leaked images have had the blogosphere buzzing in recent days.
Unless youâre a digital artist or professional photographer, you probably donât give color accuracy much consideration. But if youâve ever wondered why little Johnny looks a bit green when youâre flipping through digital photos on your laptop, maybe you should. While the color accuracy of your LCD remains a topic largely of interest to the pros, digital photo expert Rob Galbraith found that even inexpensive laptops can have great color⦠and some of the sacred cows of the business may not be as sophisticated as youâd think.
40 years ago, the first two computers on the ARPAnet â the military-run precursor to the Internet we know today â were connected to each each other, creating the first link in what would arguably become the most important technological advance in history.
