I had to. And I always use Docker for this, of course. But I also need to use Xdebug in order to debug those legacy projects, and common Xdebug installation procedures don’t work with outdated PHP.
If fact, if you try, you will get back something like this:

During these days I’m working on a PHP project based on manipulation of PDF files uploaded by users. Documents must be truncated, splitted to images, quality reducted, etc.
Because of the project’s nature, libraries’ inclusion is problematic, so I was forced to study a solution for the issue that involves only PHP official extensions. The result is some code based on ImageMagick extension.
In this post I’ll note down what I found because I hope that it can be useful for someone in my own situation.

Chiunque abbia mai avuto il piacere o il dispiacere, a seconda dei casi, di trovarsi alle prese con un linguaggio di programmazione, saprà già a cosa si riferiscono queste due parole.
Si tratta del più classico degli esempi informatici per eccellenza: il primo che solitamente si incontra in qualsiasi manuale, guida o corso di programmazione.
Qualsiasi sia, infatti, il linguaggio a cui ci si sta approcciando, il primo esempio in assoluto che viene mostrato è quello che permette di stampare a video queste due famosissime parole: Hello World.

At the end of 2019 I discovered Hugo Framework, I started refactoring my personal websites and writing some posts about some solutions I had to implement to accomplish features I was wondering for. You can find more details in post How to add Iubenda prior blocking of cookie scripts to Hugo Disqus shortcode.

In recent days, I worked to convert my Wordpress-based personal website to a static blog created using Hugo framework. The result of this conversion is the blog you are reading at the moment. I made this decision because I was bored to continously update and take care of a complete Wordpress instance with the purpose of keep online a simple personal blog. But this is another story…
Anyway, I discovered Hugo Framework at the suggestion of my friend Giuseppe Pugliese (Magnetarman) and, after some scouting on official documentation, I understood that Hugo was what I was looking for: a fast and simple framework to build websites.

Il prossimo 14 Dicembre la U.S. Federal Communications Commission, ente che regolamenta il traffico Internet negli Stati Uniti, deciderà se abolire o meno il principio della Neutralità della rete (conosciuto come Net Neutrality). La decisione non riguarda solo la regolamentazione negli USA ma, ovviamente, le ripercussioni saranno di livello globale.
In parole estremamente semplici, la Net Neutrality è quella norma che impedisce ai provider di servizi Internet di penalizzare o favorire il traffico generato da un determinato fornitore di servizi.

Lo scorso 4 novembre, durante la ScotlandPHP Conference 2017, ho avuto il piacere di assistere ad un inspirato intervento di Adam Culp sul tema dello sviluppo di codice pulito. Ho trovato tale intervento particolarmente interessante perché, se pur ribadendo concetti che tutti gli addetti ai lavori conoscono (o dovrebbero conoscere), Adam ha voluto porre l’accento sull’aspetto professionale della questione e sulle responsabilità dei soggetti coinvolti.
L’idea che molti hanno dello sviluppo software (talvolta anche in ambienti professionali) è che il lavoro consista semplicemente nella scrittura, nel minor tempo possibile, di codice privo di errori di sintassi e che restituisca l’output desiderato.

Normally in ZF3 MVC projects, each controller action matches one view and use it to render its output.
Occasionally, we may want to build your ZF3 pages by dispatching various controllers from within the matched controller and merging outputs into a unique final view. In this way we can aggregate one or more views to create complex pages like report summaries or widget dashboards.
In this post, we will see how to write few lines of code to include output of an arbitrary action into action matched from route.

Zend Service Manager component is Zend Framework’s implementation of service locator pattern. This object is very usefull component for an application and is largely used in ZF applications.
Unfortunately in ZF3 default application, Service Manager component is no more available in controllers.
An official solution exsists for this, but in this little tutorial, I want to share an easy solution to inject Service Manager in all controllers.
To implement this solution, we will write our controllers by extending an abstract controller class written to handle a Service Manager instance.
