[PHP-DEV] Fatal error: Call to a member function on a non-object
Hej, I use PHP 5.2.6. I am refactoring some code to use more object-orientation. I encounter a problem, where the new object-oriented version results in a fatal error, where the old array-oriented version didn't. I fetch records a database. Sometime it happens that a record does not exist anymore. Let's assume it's a user, then $user will be NULL. echo $user['fullname']; // no error at all, $user['fullname'] === NULL Shouldn't this at least trigger a Notice? echo $user-get_fullname(); // Fatal error I agree this should trigger an error, but a Fatal error is a little too much, I think. It terminates the script leaving the html-document incomplete. I would prefer a Warning and NULL instead. Is there any reason against it?

Re: [PHP-DEV] Fatal error: Call to a member function on a non-object
W liście Christopher Vogt z dnia poniedziałek 17 listopada 2008: I have a good understanding of OOP. This is not a start for me. I am just refactoring existing PHP code to be object-oriented. You say there are plenty of reasons for a Fatal error, so please tell me a few, so I understand the reasons. You're calling a method. This requires code execution, but the code isn't there. If you were accessing a property of non-existing object (that is, if you were doing $user-fullname;) then you'd get a warning and NULL. It's not so for functions, as they're request for code execution, not for value (remember, not all functions return values as they most important effect - it's not Haskell). Calling non-existing function returns in fatal error in PHP; it's the same for: $object-iHaveNoSuchMethod(); $null-method(); nosuchfunction(); -- Paweł Stradomski -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php

[PHP-DEV] Re: Namespace resolution rules has been changed?
true, however i have a counter example: classes from more general namespace that use further nested classes (think some kind of behaviour and different drivers/plugins for example). so while it's true that more nested classes usually extend the less nested ones it also common for more generic code to use it's namespace descendants. in sutch condition possibility to use just the remaining namespace part is a big help and i'd say it's usage would be more comon than single extends at class definition where you're obligated to supply FQN [1]. The more generic code (i.e. application code) is located usually in its own namespace, so it must use FQN. FQN with leading backslash.

[PHP-DEV] Re: Namespace resolution rules has been changed?
Try to answer the question: what is the $obj instance of?
namespace foo;
$obj = $factory-loadClass('bar\class');
---
$factory is implemented cca this way:
namespace ?;
class Factory
{
function loadClass($class) {
return new $class;
}
}
With absolute FQN is the answer evident. With relative FQN it is very
esoteric.
With relative FQN developers will have to implement save loadClass()
this way:
function loadClass($class)
{
if (strpos($class, '\\') !== FALSE strncmp($class, '\\', 1)) {
$class = '\\' . $class;
}
return new $class;
}

That is, 0 == false 0 == 0.0 But false != 0.0 The answer to why is, well, that's the way it is. 0.0 just looks too much like a string, maybe, to be made into a boolean.

Re: [PHP-DEV] Re: Namespace resolution rules has been changed?
Zend_Acl == Zend_Acl_Resource_Interface, Zend_Acl_Role_Interface, Zend_Acl_Role_Registry, Zend_Acl_Assert_Registry... Regard, Stan Vassilev Stan, ZF doesn't use namespaces yet. This is not namespaced code. Namespaced code requires different convention (http://framework.zend.com/wiki/display/ZFPROP/Naming+conventions+for+2.0+-+Matthew+Ratzloff). In namespaced code there cannot be class Interface in namespace Zend\Acl\Role. There must be class RoleInterface in Zend\Acl namespace. Similary class Zend_Acl become Acl in Zend\Acl namespace. So look at the code with namespace-eyes. Classes Zend_Acl, Zend_Acl_Resource_Interface, Zend_Acl_Role_Interface... will exist in one namespace. I've checked that wiki page before, and I'm following with interest how they end up naming those, but that changes nothing. Today, Zend_Acl uses Zend_Acl_Resource_Interface. Tommorow, Zend\Acl uses Zend\Acl\ResourceInterface (or similar). The fact is, PHP frameworks and especially Zend use plenty of factories and facade classes, which by definition reach into inner-more classes and provide simplified paradigm to the outside world. The Interface and Exception classes won't stay like this, but they'll still be inside a subnamespace.
