How to find the line on which execution was interrupted in PHP

When working with old code, it is sometimes very difficult to find the place where execution was interrupted. Constructions like die, exit, etc. are very bad practice, but there is a lot of legacy code (and not only - I'm not saying anything bad about Wordpress, so I'll keep quiet) that abuse them. One of the biggest problems with such constructions is that they are difficult to find and debug. (Use exceptions!)

But when the task is to find the place where code execution is interrupted, you can use the following snippet:

Refreshing Nested Set Tree Indexes in Symfony


Once I used Nestedset behavior for Doctrine, Symfony in a project, and faced issue with broken indexes. (You can read how Nested Set works here). This happened because low-level MySQL query executed during migration, and because of this Doctrine events responsible for refreshing indexes was not executed. To fix that a Symfony Command was written, which refreshes indexes. This is just example. Better way is to move this code to the service and add one more migration which will refresh indexes. Here is just simple example how this issue can be solved.

Argument of the command is an entity to refresh.

Uploading files in Symfony

Uploading files in Symfony is conceptually no different from other PHP platforms, but still has its own features due to the presence of additional tools provided by the framework.

First of all, it is worth noting that there are ready-made solutions that solve the task at hand. I strongly recommend familiarizing yourself with them, and only after that, if you decide that they do not suit you, implement your own solution.

In this note we will try to show possible ways to solve the task, using both ready-made solutions (VichUploaderBundle, IphpFileStoreBundle), and using our own implementation (in Symfony controllers and admin classes from the SonataAdminBundle).

Adding comments to the website

Honestly, when I saw that they write about it and give advice to beginners on other sites, I was a little horrified and decided to create my own note on this topic without a "fatal flaw". Mostly, I saw long pieces of code that implement adding comments to a site. Usually, for this, a form is created, its processing, storage, and also selection for display are implemented. But the advantages of such an approach are diminishing over time.

In this note, you will learn one of the simplest (but subjectively one of the most preferred) ways to add comments to a site - a simple example for beginners + options for more advanced webmasters.

Indeed, why invent the bicycle and write a lot of code that will have to be maintained, fixed, etc. in the future, if there are plenty of ready-made solutions from third-party services (we are talking about social networks + disqus)?

Asset versioning when using gulp

assetsWhen changing client code, you need to somehow force the client's browser to reload the modified files. This problem is quite common. Most likely, you will encounter it regardless of the technologies you use in web development. This example is about solving the problem when creating a frontend project using JavaScript and Gulp.

You can solve it in several ways.

Let's say, for example, 7e50961489 is the new version of the assets. Actually, it can be any version, the main thing is that it should be different from the previous ones. You can simply number them - 1, 2, 3, etc. But it's not very convenient. Later it will be clear why.

Sequence Master Game

Sequence Master Game - a game to test reaction speed. Click on the largest number among the available ones (you can choose multiple numbers at each step) and share your high score with friends.

Key features/gameplay:

1) There are 7 levels available

2) Within the given time, you must click the numbers from largest to smallest.

3) Points are awarded for each selection. The number of points depends on the player's selection speed and the value of the selected number. In case of a mistake, the game does not end, but a penalty is applied.

4) The game ends if you fail to select the correct number within the allocated time. After the game ends, you have the option to share your results.

5) Responsiveness (should work on smartphones), animation, and other bells and whistles =).

Gulp file for frontend project

The solution is not perfect. But it is suitable for developing a small frontend project written in coffeescript and less. Important note: the use of backend is not provided. Nodejs is only used for building assets (this solution is convenient, for example, if you plan to create a hybrid offline application for smartphones).

The key features of our project, and as a result, the gulp file:

1) Supports different environments (prod, dev, etc)

2) Compilation and minification of less, CoffeScript files, combining multiple into one (concatenation)

3) Support for tests (jasmine)

4) In the dev environment, watch is functioning (dynamically rebuilds assets when source files are changed)
