This work is done to try to solve a scientific computer problem and its basis derived from the web, as there are a variety of ways to program to it. The most common languages used by developers, both private and corporate are PHP, .NET and Ruby. But why do companies or a private developer choose a specific programming language? Is it because it is better and has more features than the others, or because they are forced? This essay uses a questionnaire and through tests sees which is best and which one is the most popular/used. To illustrate the problem, a survey is conducted and sent to several companies and asked them to answer the questions regarding the issue. There are also programming exercises in which attempts to explain and solve the problem. The conclusion shows that you can make two similar sites in two different programming languages without any problems, if the developers do it in a similar way as we conducted our lab. It can be assumed that it is possible to do this with most of the sites you want to build, since most functions are available in both languages.
