Hi everyone,
Dependency Injection is a very trendy subject and after reading about it I
kinda thought about rewriting the framework I'm doing with dependency
injection. So I made my own implementation and was wondering what would you
think about it? I have followed the article of Martin Fowler (
http://martinfowler.com/articles/injection.html)
with this implementation I have the following :
- you have both constructor and setter injection
- the Dependency class is a service locator
- we have at the same time service locator AND dependency injection
- you can always manually inject dependency
- you can pass arguments to the injected object constructor
So: am I missing something? Do you think it's good enough?
here is the code :
<?php
class Dependency {
protected $_singletonInstances = array();
protected $_setInstances = array();
protected $_configuration;
public static function getInstance() {
static $instance = NULL;
if (NULL === $instance) {
$instance = new static();
}
return $instance;
}
public function setConfiguration(array $configuration) {
$this->_configuration = $configuration;
}
public function getConfiguration() {
return $this->_configuration;
}
public function __isset($serviceName) {
return isset($this->_serviceInstances[$serviceName]);
}
public function __call($serviceName, $args) {
// singleton
if (isset($this->_configuration[$serviceName]) &&
$this->_configuration[$serviceName]['singleton']) {
if (!isset($this->_singletonInstances[$serviceName])) {
$rc = new
\ReflectionClass($this->_configuration[$serviceName]['class']);
$this->_singletonInstances[$serviceName] = empty($args) ?
$rc->newInstance() : $rc->newInstanceArgs($args);
}
$ret = $this->_singletonInstances[$serviceName];
} else {
// normal
if (isset($this->_setInstances[$serviceName])) {
$ret = $this->_setInstances[$serviceName];
unset($this->_setInstances[$serviceName]);
} else {
$rc = new
\ReflectionClass($this->_configuration[$serviceName]['class']);
$ret = $this->_singletonInstances[$serviceName] =
empty($args) ? $rc->newInstance() : $rc->newInstanceArgs($args);
}
}
return $ret;
}
public function __get($serviceName) {
return $this->__call($serviceName, array());
}
public function __set($serviceName, $instance) {
if (!is_object($instance))
throw new Exception('instance must be an object');
$this->_setInstances[$serviceName] = $instance;
}
}
class DependencyInjectorException extends \Exception {
}
$di=DependencyInjector::getInstance();
$di->setConfiguration(array(
'database.connector'=>array(
'singleton'=>true,
'class'=>'DatabaseConnector'
),
'database'=>array(
'singleton'=>true,
'class'=>'Database'
)
));
class DatabaseConnector{}
class Database{
protected $_connector;
public function __construct(){
$this->setConnector(DependencyInjector::getInstance()->{'database.connector'});
}
public function setConnector($connector){
$this->_connector=$connector;
}
}
class Test{
protected $_database;
public function __construct(){
$this->setDatabase(DependencyInjector::getInstance()->database);
}
public function setDatabase($db){
$this->_database=$db;
}
public function getDatabase(){
return $this->_database;
}
}
$test=new Test();
var_dump($test->getDatabase());
?>

Hi
I'm afraid I've fallen a little out of touch with PHP dev, so a stupid
question for you.
I want to write a script that requests a URL and then reads that website
.. I'm interested to map web structures. My web host is saying I'll need
URL file access enabled but that it's a) a security risk and b)
deprecated.
So .. what's the good / proper / acceptable / secure way of reading in
URLs in PHP or .. isn't there one?
Cheers
J

simplehtmldom is pretty great for this, if I understand your needs
correctly... also not sure about it's server setting requirements, but
worth a look..

Another option is cURL www.php.net/curl

cURL is the best one in my experience, but you have to manage security
yourself. Meaning: Remember to escape/encode data.

Silence.... ?
I havn't got any responses from drupal.org, and i think its very quiet
here too?
Should I start to analyze the code to understand the inner workings? Can
anyone give some advise on where to get more information?
Or... is there another proven way to communicate between Flash and
PHP/Drupal?
Regards
Lars Nielsen

Hello all.
Not sure just how much of this is PHP related, but hoping someone has
come across this before.
I Google's webmaster tools for a site I work on, they list more than
100 crawl errors for pages with URL's as follows:
http://mydomain.com/My-Directory/function.session-start
Can anyone explain why webmaster tools is seeing pages with links
ending in "function.session-start"? I read up on the error itself...
sometimes caused by whitespace before the session_start tag... have
fixed that. Any info is appreciated.

Off the top of my head, check to make sure your robots.txt is in
order, see http://www.robotstxt.org/robotstxt.html

You have PHP errors somewhere on your site. The error messages contain links
that could result in those URLs. Find out what pages are linking to those URLs
and check them for errors.

WRT functions: while I could see how this would seem like a good idea
because of the symmetry in what's going on at a very high level of
abstraction, I would be against including it in a language. I don't
particularly like it for arrays, but it does make it easy to add items
into an array, which happens pretty often in development, especially
when writing exploratory code. Function signatures, on the other hand,
probably aren't changing nearly as often.
At the very least, I wouldn't want to encourage people to make
functions with many parameters, as it's normally a sign of poor
design. This wouldn't explicitly do so, but would do so implicitly as
it's only real purpose is to make it easier to add things.
As far as the supporting-a-leading-comma thing goes, I'm pretty
ambivalent on it. I don't really like the style outside of Haskell
code, but that's just a preference.
