Google Voice and its awesomeness

So here is an embedded voicemail from google voice, which manages all my sms, and voicemails. very slick.

self:: vs this->

Here is an example of correct usage of $this and self for non-static and static member variables:

PHP Code:

class X {
private $non_static_member = 1;
private static $static_member = 2;

function __construct() {
echo $this->non_static_member . ' '
. self::$static_member;
}
}

new X();
?>

Here is an example of incorrect usage of $this and self for non-static and static member variables:

PHP Code:

class X {
private $non_static_member = 1;
private static $static_member = 2;

function __construct() {
echo self::$non_static_member . ' '
. $this->static_member;
}
}

new X();
?>

Here is an example of polymorphism with $this for member functions:

PHP Code:

class X {
function foo() {
echo 'X::foo()';
}

function bar() {
$this->foo();
}
}

class Y extends X {
function foo() {
echo 'Y::foo()';
}
}

$x = new Y();
$x->bar();
?>

Here is an example of suppressing polymorphic behaviour by using self for member functions:

PHP Code:

class X {
function foo() {
echo 'X::foo()';
}

function bar() {
self::foo();
}
}

class Y extends X {
function foo() {
echo 'Y::foo()';
}
}

$x = new Y();
$x->bar();
?>

The idea is that $this->foo() calls the foo() member function of whatever is the exact type of the current object. If the object is of type X, it thus calls X::foo(). If the object is of type Y, it calls Y::foo(). But with self::foo(), X::foo() is always called.

CSS clutter, resolved

It might be an old trick, but i like it. when you find yourself linking to many CSS files and want to clear up some of them, just link to one, and use:

@import url("common.css");
@import url("links.css");
@import url("content.css");
@import url("buttons.css");
@import url("cp.css");
@import url("forms.css");
@import url("tweaks.css");
@import url("colours.css");

ajax + back/forward + bookmark

so, not only does this site do a great job of using ajax in a very pretty way, but it supports a simple back forward bookmarking method, as well as linking.

Useful PHP - jsCheck

I just came accross this PHP class, it is definetly useful for web 2.0 style sites that rely heavily on javascript. Using only PHP it checks to see if javascript is enabled.

This class can be used to check whether Javascript is enabled in the browser.

It can generate a HTML form with Javascript to automatically submit it when the page is load.

The class can set cookies or session variables to avoid the need to generate the form to check again if the browser has Javascript enabled.
