Hello. This is my jubilee article on the habr. For almost 7 years I wrote 10 articles (including this one), 8 of them - technical. The total number of views of all articles is about half a million.
 
I made the main contribution to two hubs: PHP and Server Administration. I like to work at the junction of these two areas, but the scope of my interests is much broader.
 
Like many developers, I often use the results of someone else's work (articles on the habr, code on the githaba, ), so I'm always glad to share with the community my results in response. Writing articles is not only a return of ...

 
 

History

 
A little background. The first version of Shopkeeper was released in 2009. Then it was a module for CMS MODX , or rather for its first branch, which is now called Evolution. At that time MODX had only one such module, but its quality did not suit me, so I decided to write my own. Plus, I needed some kind of project to increase my experience in programming in PHP. Because there was almost no competition, my component became the most popular for that version of MODX.

It all started when it came. Mysterious letter from Vladimir (?!) customs. Inside, there was a demand to provide statistical data on trade with Belarus and Kazakhstan for the whole of last year. And the reference to the decree of the sovereign, as it should be.

The name of the autoCommit option may give the impression that at autoCommit = true commit is called automatically, and at autoCommit = false it must be called by hand, but it is not.
 
 
autoCommit = false
 
In this mode, new transactions start automatically (the first one at the connection, then when you call commit /rollback), that is, all requests are always executed inside the transaction, you must manually call commit /rollback to complete them.
 
 
autoCommit = true (the default value)
 
In this mode, transactions do not start automatically, they must be started by calling ...

 
 
The SOLID principles are a programming standard that all developers need to understand well in order to avoid creating a bad architecture. This standard is widely used in OOP. If you apply it correctly, it makes the code more extensible, logical, and readable. When a developer creates an application based on poor architecture, the code turns out to be inflexible, even small changes in it can lead to bugs. Therefore, you must follow the principles of SOLID.
 
 
It takes some time to master them, but if you write the code in accordance with these principles, its quality will improve, and you will master ...

Today Adobe announced that buys Magento for ??? billion dollars .
 
This purchase will give Adobe the missing part of the e-commerce platform, which works in the B2B and B2C segments and must perfectly fit into the company's cloud stack.
 
 
This should also help Adobe compete with Salesforce, which offers its cloud platform and which is bought Demandware for more than $ 2 billion in 2016 to offer a similar functionality.

Due to the fact that the previous service with which I stored the images covered by a copper basin (most likely because it was not profitable), I had to look for other options for storing images. The server I use is budget and I would not like to pay a decent price for an additional 10 GB of disk space. Studying the market, I came across Google Cloud Storage ( CSS ) And decided that this product would work for me (well, at least you can test it). In runet (and not only in it) little attention is paid to setting GCS using PHP, so I decided to do my bit in this direction.

The Internet already has a lot of books, articles, and the same posts on the habra for beginners. But, as for me, there are a number of nuances that are usually or not mentioned at all (apparently, they are considered obvious), or they are very rarely mentioned. And this is not advice from the series "study the code of other developers", "use git", "make backups" or "wash your hands before going to the production console." These are ordinary, practical things that come with some experience. Some of them are not useful if you use the most advanced approaches to development, some of them are universal...
