Reverse engineering

Third party apps

After some time using an application, the need may arise to make a touch-up, add some functionality, or even change it drastically.

But it turns out that we no longer have contact with the original author, or he has completely abandoned the development and maintenance of such application, which is essential for our activity.

Who touches it now? I assure you that it is not easy to dive into the code of a program written by another and about whose development you do not have any documentation.

Know how it is made and how it works

In these cases, you have to reverse engineer, to get to see the skeleton of the program, everything that covers it, and understand how each part works.

It is not easy at all, and requires knowledge, but extensive experience as a developer also helps a lot. Having participated to a lesser or greater extent in different projects allows you to identify which development strategies were used in general, and which techniques in particular.

Adapt your old application to PHP 7 or PHP 8

A very common need is to prepare an application that was made for PHP 5.6, or even lower, to work properly under PHP 7 or PHP 8.

Does it sound familiar to you? Time ago, somebody developed for you an application with PHP, which you have been using for years, and it's essential for your business. But now, your hosting force you to upgrade to PHP 7, or to PHP 8, and the application drops errors and warnings everywhere.

Don't worry, it's possible to review it and make it compatible with PHP 7 or PHP 8, there is no need to completely redo the application. Typically, at least PHP 7.3 is desired, and PHP 7.4 is recommended, however branch 7 is now deprecated in favor of 8.
