If you can recommend some good, clear books/websites to explain strategy/structure, like where you learned it, that would help tons. I’m always searching.
To be honest, there's a lot of bad information out there on PHP. I learnt to program in Java which is designed around OOP. That helped. With PHP I mainly learnt by building things. Robert Martin's "Clean Code" book and Martin Fowler's "Patterns of Enterprise Application Architecture" were really helpful and I still refer to those. People like Tom Butler are great to refer to for being very disciplined about how they design applications using OOP, and python helped me to understand the notion of using immutable objects to help with this. I'm still trying to improve my architectural decisions.
I haven’t been able to get to work on this during holidays. Just getting back to it now, with a quick question.
I’ve seen a ton of posts about Laravel on places like Reddit, wondering if it’s something I should try. Or should I stick with raw code, thereby learning it better? I don’t need another “language” (learning curve) to try to surmount in the midst of all this. Do you use Laravel or some other framework/library?
Do you use Laravel or some other framework/library?
Sometimes. I've not used Laravel, but I haven't built large projects before from scratch so it would be overkill for me. I'm starting a larger project now in my free time that I want to build using a MVC paradigm broadly in line with Tom Butler's writing (which is why I'm here). Those frameworks would be tricky to adapt to that ideology.
I must stress that I'm a hobbyist - I program in my free time to make things I find useful to me.
should I stick with raw code, thereby learning it better?
I think it depends on what you are trying to do. If you're trying to learn MVC architecture then there's no point using Laravel as they've made all those decisions for you. You'd just be learning how to use Laravel. If you want a framework to help you learn OOP it might be easier to use a smaller framework that you'll find easier to understand. Frameworks are just tools - it's best to know what you want to achieve before picking which tool to use.
public function output() {
$html = '<form action="?action=authen" method="post">'
. '<input name="username" type="text" /><br>'
. '<input name="password" type="password" /><br>'
. '<input value="Submit" type="submit" />';
return $html;
}
public function alert($msg) {
echo "<script>alert('$msg');</script>";
}
public function redirect($url) {
header("Location: $url", true);
}
After what seems like a very long time in development, I am pleased to announce I am launching a new website:
As part of my Ph.D research I'm developing a a metric for grading source code flexibility by identifying known bad practices (For example, global variables and singletons).
To test this metric, I've developed a tool which scans source code (Currently PHP) for bad practices which are known to make the code inflexible. It grades the code and highlights areas where flexibility can be improved.
Insphpect is currently in the testing phase so don't expect it to be perfect, but it's good enough to start to get some feedback!
If you're a PHP programmer who writes OOP code upload your code and complete the survey to tell me what you think! You can either provide a git repo url or upload a zip file.
Alternatively, if you're not a PHP programmer but do OOP in another language, take a look at the sample reports and complete the survey based on the recommendations given. You can also let me know if you'd like to see something similar for other languages.
Completing the survey is very beneficial to my research but if you have any informal suggestions I'm happy to take them on here.
Example 1:
$user = $user->load(1);
$user->disable($user);
$user->save($user);Example 2:
$user = $user->load(1)->disable()->save();
$user = $user->load(2)->password('test')->save();Example 3:
$loaded = $user->load(1)->getUser();
$loaded['disabled'] = 0;
$user->save($loaded);Questions that comes up from reading "Immutable MVC in PHP (Part 2) - Immutable CRUD application"
Example 2 is what seams like its the way to go but how do I manage user creation in that case. Make the load method take an array so methods like disable and password can work their magic like password hashing. Another way would be if I let the Save method take the array methods like password and disable won't have the ability to set anything before the new user is created. Or should I pass a new user array into the construct at startup?
class Request {
public function __construct($uri, $params) {
$this->uri = $uri;
$this->params = $params;
}
public function getUri() {
return $this->uri;
}
public function setParam($key, $value) {
$this->params[$key] = $value;
return $this;
}
public function getParam($key) {
if (!isset($this->params[$key])) {
throw new \InvalidArgumentException("The request parameter with key '$key' is invalid.");
}
return $this->params[$key];
}
public function getParams() {
return $this->params;
}
}
I want to see a finished example
small site skeleton
I was wondering, cause everything makes sense as long as its a single responsibility. Like a page for a report or a user profile or whatever you can come up with. But when you come to a home page witch can be a bit of everything like an overview.
The question is:
- Do I repeat the functionality of other models in the model?
- Do I use models in a model?
- And do I call the models, model in that case?
-- Model --
class Home {
public $welcomeMessage;
public $houses;
public $cars;
public $blog;
}
-- View --
<h1>Store</h1>
<p><?php Home->welcomeMessage; ?></p>
<h2>Cars I own</h2>
<table>
<?php foreach(Home->cars->owned as $car):
<tr>
<td>$car...</td>
</tr>
<?php endforeach;?>
</table>
<h2>Houses For Sale</h2>
<table>
<?php foreach(Home->houses->sale as $house):
<tr>
<td>$house...</td>
</tr>
<?php endforeach;?>
</table>
It's probably not a difficult refactor, replace new Foo() with $foo and pass in the instance as a constructor argument. You'll also need to change anywhere the top level class is instantiated to supply the constructor arguments.... or instantiate it with the DIC.
( insphpect.com can actually somewhat do this automatically and generate a patch, it's a bit buggy at the moment and needs tweaking... when I have time I'll release the code)
The file was rather popular and ate the limited bandwidth on the dirt cheap vps hosting my blog
public directory and access it on v.je/phpmyadmin or place it in its own subdomain. Better yet, use something more modern and faster like MySQL Workbench
