OOP concepts in PHP 5 in brief #16

By Author-Check- Article-or-Video in FromSitesTree.com

OOP concepts in PHP 5 in short Why this short – note? if you are familiar with OOD and any OOP language such as Java/C++, this short note will give you enough information to start with PHP 5 OOP Class

Class definition starts with the keyword class, followed by a class name (non reserved word), followed by a pair of curly braces. The curly braces contain the definition of the classes members and methods
You can create objects based on the classes. $obj = new className()
You use $obj->methodName() to access a class method (public). You can use className::classMember to access class members (static): to use :: operator the method does not need to be declared static
Inside a class all class methods have access to $this variable to refer to the calling object (if called from/using an object)
member declaration: public $var = ‘a default value
Default value always is: constant expression
Class/Object Functions
A class can use extends keyword to inherit methods and members of another class
Multiple inheritance is not allowed
To avoid using a long list of includes in the beginning of php files, you can use __autoload() function to do the job for you
When you try to use an undefined class/interface an __autoload function is automatically called

function __autoload($class_name) {                 
   require_once $class_name . '.php';               
}

Constructor syntax: void __construct ([ mixed $args [, $… ]] )
Parents’ constructors are not automatically called from children’s constructos. use explicit parent::__construct() instead
Destructor syntax: void __destruct ( void )
Destructor is called: 1. all references to the object are removed 2. the object is explicitly destroyed 3. in shutdown sequence
Parents’ destructors are not automatically called from children’s destructors. use explicit parent::__destruct() instead
Access modifiers for class members: public, protected or private: Public – accessible from anywhere. Protected – accessible from inherited and parent classes, within the class. Private – accessible within the class
No access modifier = public
:: – scope resolution operator – allows access to static, constant, and overridden members or methods of a class
Abstract classes: Introduced in PHP 5. You are not allowed to reate an instance of an abstract class.
Even if a class contains one abstract method, the class must bedeclared abstract
Abstract classes are just about signatures, they cannot define the implementation
A class inheriting from an abstract class, must have to implement all abstract methods. The abstract methods must be defined with the same/(less restricted) visibility
Interface: Just the method signatures. No method implementation inside interfaces
All interface methods must be public
Classes implementing interfaces must implement all methods. Classes use implements keyword to implement an interface
A class can not implement two interfaces having same class names
Interfaces can be extended using extends keyword
Interfaces can also have constants
Overloading: Overloading in PHP = dynamically “create” members and methods
overloading methods: invoked when interacting with non-declared/invisible members or methods
All overloading methods must be defined as public
In PHP, overloading is done through magic methods
The arguments of the magic methods can not be ‘passed by reference’
Member overloading methods: void __set ( string $name , mixed $value ), mixed __get ( string $name ), bool __isset ( string $name ), void __unset ( string $name )
Method overloading: mixed __call ( string $name , array $arguments ), mixed __callStatic ( string $name , array $arguments )

Object Iteration: Inside the class

foreach($this as $key => $value) {                  
   print "$key => $valuen";              
}

Object Iteration: Outside class:

$class = new MyClass();               
foreach ($class as $key => $value) {                 
   print "$key => $valuen";
}

Patterns: Factory Pattern: allows the instantiation of objects at runtime
Patterns: Singleton: Helps in situations where only a single instance of a class is required that will be used by many other objects
Magic methods: have special meaning. __construct, __destruct (see Constructors and Destructors), __call, __callStatic, __get, __set, __isset, __unset, __sleep, __wakeup, __toString, __set_state and __clone
serialize() – applies to __sleep(). unserialize() applies to __wakeup()
final keyword: final members can not be overriden, final classes can not be extended
$copy_of_object = clone $object; : will create a clone of $object. Unless a __clone method defined, a shadow is created. __clone() method can define how the cloning will be done
Objects Comparison: == : two object instances are equal if they have the same attributes and values, and are instances of the same class.
Objects Comparison: === : Object variables are identical if and only if they refer to the same instance of the same class
Reflection APIs: to reverse-engineer classes, interfaces, functions and methods, extensions
Reflection APIs: Offer ways to retrieve doc comments for functions, classes and methods
Type Hinting: Functions can enforce parameters to be objects:
Late Static Bindings: to refer the called class in a context of static inheritance.

Drupal PHP Yahoo Webhosting Register Globals #16

By Author-Check- Article-or-Video in FromSitesTree.com

If you search google (with terms like ‘Drupal Yahoo Hosting’), you will see many people are having troubles to install Drupal under yahoo web-hosting. The issue is with the register_globals (php_ini) variable. They are too frustrated to give up either Drupal or Yahoo Web-hosting. Yahoo did not make the required changes for them (in php.ini). However, the solution (good or bad – you decide) is pretty simple.

Just open the file: /drupal-6.6/modules/system/system.install and change the following line:

$register_globals = trim(ini_get(‘register_globals’));
to
$register_globals = ”;

and you are done. (Drupal – 6.6). [I know – having register_globals to be on is not secure.]
