If you are a complete scraping beginner, this article is for you. If not, move on, because we are going to learn about scraping and parsing, but without using regular expressions or any supporting libraries. Moreover, we will do it using basic PHP string functions. Sure, PHP is not the best language choice for scrapping and parsing but it’s easy to learn and comprehend so it is a good candidate for beginners. First, we are going to explain what parsing is. Then, we are going to have a look at arrays, the GET method, stream_context_create and file_get_contents functions. Afterward, we are going to apply the strpos and substr functions, and at the end of this mini-project, we are going to display the results using print_r function.

Desktop apps, mobile apps, and web apps. Apps are everywhere. In the past years, as hardware became more powerful, the tendency to merge apps between desktop, mobile, and web platforms is higher than ever. And, in accordance with that, we meet more and more programming languages and frameworks that we can use on every platform with a minimal trade-off in terms of code difference, app execution speed, and even user interface.
In this article, we are going to answer the question of how to make a (mobile) app as a total beginner. The answer requires a multi-faceted approach, starting with the perspective of the person that is asking that question. Are you an aspiring developer who wants to learn how to develop an app? Are you an eager product manager? Or are you an ambitious startup owner?

However, this reserved keyword cannot stand alone and is closely connected to another reserved keyword – “while”.

Let’s go through a few examples and see what is the purpose of the “do” keyword in the do-while loop.
