But those pages, when loaded, do not display any PHP errors. Only
webmaster tools is showing the function.session-start in a link to
that page. When I looked up hte meaning of session-start function, I
found others who have indicated that white space in front of the
session tag can cause this... so I eliminated it. Not sure if that
will fix as the page has never displayed an error and Google takes
forever to recrawl the whole site.

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.
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.

I have a class that takes as input, an array by reference and stores it in a
member variable. A method in this class later modifies the member variable
(which contains reference to the array). When I access the local variable
that was passed by reference to the constructor of this class object, I see
the local variable hasn't changed at all. I think code will describe what
words may not have:
<?php
class foo
{
public $_bar;
public function __construct(& $bar)
{
$this->_bar = $bar;
}
function do_your_thing()
{
$temp = array(
'One' => 1,
'Two' => 2
);
$this->_bar[] = $temp;
echo('from Do_your_thing: ');
print_r($this->_bar); // ---------------- [1]
}
}
$abc = array();
$var = new foo($abc);
$var->do_your_thing();
echo('from main [local variable]: ');
print_r($abc); // ---------------- [2]
echo('from main: [object member variable] ');
print_r($var->_bar); // ---------------- [3]
?>
I expected the output from [1], [2] and [3] to be the same. But instead I
get the following:
from Do_your_thing: Array
(
[0] => Array
(
[One] => 1
[Two] => 2
)
)
from main [local variable]: Array
(
)
from main: [object member variable] Array
(
[0] => Array
(
[One] => 1
[Two] => 2
)
)
What am I missing? Please help, I'm new to PHP and this is really blocking
me.
Thanks

You have to assign the value by reference too
public function __construct(& $bar)
{
$this->_bar = &$bar;
}

Hi,
I am trying to avoid reinventing the wheel so I am looking for
dependency injection containers that work with PHP 5.2. So Symphony2
and ZF2 DI are out of question.
I found this
http://www.potstuck.com/2010/09/09/php-dependency-a-php-dependency-injection-framework/
but I was wondering if anyone has a opinion about it or alternatives.
regards.

Hi,
you could simply write your own, you simply need a class or a function that
given an identifier such as "database.connector" would return you an
instance of it, and
and maybe handle singletons.
It just a question of taste of how you want it to be.
I have just posted a few days ago my implementation, it might interest you
(I think it should work with php 5.2)
<?php
class Dependency {
protected $_singletonInstances = array();
protected $_setInstances = array();
protected $_configuration;
protected static $_instance;
public static function getInstance() {
if (self::$_instance===null) {
self::$_instance = new self();
}
return self::$_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;
}
}
$di=Dependency::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(){
$this->setConnector(Dependency::getInstance()->{'database.connector'});
}
public function setConnector($connector){
$this->_connector=$connector;
}
}
class Test{
protected $_database;
public function __construct(){
$this->setDatabase(Dependency::getInstance()->database);
}
public function setDatabase($db){
$this->_database=$db;
}
public function getDatabase(){
return $this->_database;
}
}
$test=new Test();
var_dump($test->getDatabase());
