PHP chaining instantiation
PHP doesn't allow you to construct an object and call a method at the same time. For example the following does not work:
$domain = new Website($id)->getDomain();
What we need to do is call a static method of the class which instantiates itself. For example:
class Website() {
public function __construct($id) {
$this->id;
//some code which grabs the websites details from a database
}
public function getInstance() {
return new Website();
}
public function getDomain() {
return $this->domain;
}
}
$website = Website::getInstance();
//same as $website = new Website();
Don't forget to put any parameters that are needed:
class Website() {
public function __construct($id) {
$this->id;
//some code which grabs the websites details from a database
}
public function getInstance($id) {
return new Website($id);
}
public function getDomain() {
return $this->domain;
}
}
$website = Website::getInstance($id);
//same as $website = new Website($id);
Now we're free to instantiate a new object and call one of its methods immediately
class Website() {
public function __construct($id) {
$this->id;
//some code which grabs the websites details from a database
}
public function getInstance($id) {
return new Website($id);
}
public function getDomain() {
return $this->domain;
}
}
$domain = Website::getInstance($id)->getDomain();
Once we have this freedom and flexibility we can chain our PHP methods together to initialise our values:
$website = Website::getInstance($id)->add($homePage)->add($contactPage)->add($aboutPage);
