WhatsApp is an application that allows you to send messages, multimedia files, videos, or photos to all devices with the most important mobile operating systems on the market. This instant messaging system has completely revolutionized the way we communicate, drastically reducing costs. And also sanctioning the probable end of sending the classic text messages, now almost unused. Most of the contacts in your address book will probably have WhatsApp.

How to change WhatsApp contact name with full customization

One way to improve the organization of WhatsApp contacts is to customize them. The first thing to do is to open the WhatsApp Settings screen. The personalization available on these contact apps is not very deep. In fact, the only customizations concerning the various WhatsApp contacts concern only a few aspects. However, if done wisely, they can really allow us to personalize contacts.

So let’s see how to customize contacts on WhatsApp. Before starting, I strongly recommend that you perform these procedures only and only if you are sure. To avoid possible damage to your mobile device.

Change background

WhatsApp is a cross-platform messaging application used to send instant messages to the people in your contact list at no cost. In addition to exchanging text messages, you can also share pictures, videos, audio messages, and user location with other people. This messaging app was developed to be used with Android, Windows, Blackberry, and iOS smartphones. You can also create groups using this app to exchange messages, images, and videos. One of the “aesthetic” customizations to do is to change the background of each chat. In this case, just click the button at the bottom left of your smartphone in the chat to customize. Choose “Background” and then select the chosen source.

Change ringtone

The WhatsApp notification is automatically displayed on the phone screen every time a new message is received. These notifications are a way of letting you know that there are new messages in your chat account. Below are the steps through which you can easily customize notifications in WhatsApp settings. For this, you have to make sure that the notification settings are “On”, in your WhatsApp account and the phone settings. Another really useful personalization of WhatsApp contacts concerns ringtones.

If a group you belong to sends you a lot of notifications per day, you can silence it. Or you can give each contact or group a different ringtone. Let’s see how to customize WhatsApp contacts in this sense. Go to Settings and then to Notifications. From here, you can choose the tone of the notifications and the different ringtones for your contacts.

Customize a group

If you want to customize a WhatsApp group instead, follow the same procedure. Open the Settings and then the Notifications. Scroll down and you will find Group Notifications. From this screen, you can choose the ringtone for new notification messages. If you assign two different ringtones for groups and individual contacts, you will already know if you are interested in answering.

Or maybe the answer can wait because it is only one of the hundreds of notifications from one of your groups. You can also set message sound alerts for different groups, according to your choice. For this, there is an option available in the settings for WhatsApp.

Today we will talk about PHP vs Python ​​with a lot of history and arouse passions and hatred alike, depending on who you ask. However, it is true that due to its characteristics, Python is more complete than PHP because it also allows you to develop software for the desktop, mobile in addition to games.

Programming is the foundation of the digital world today. Since its inception, we have improved and developed new languages ​​to create more efficient programs and websites. It is precisely in the field of web development that further changes have occurred in what we have been in the 21st century. PHP is a programming language used to create applications that can be run from a computer or a mobile application. Now, I will share how to open PHP file in chrome and other systems.

If you dedicate yourself to designing simple static pages and their content will not change very often, you can manage with just HTML. An example can be a business website that shows data about the company, its location, recent jobs, means of contact, etc. All data is almost constant. But how PHP works? Each visitor who enters said website will process the HTML code through their browser and will be able to view all the content.

Now suppose that the company decides to add a blog on the web, something that will benefit the interaction with its customers. Will we solve it with HTML? It is a possible solution, but keep in mind that every time new content is uploaded, you will have to enter to modify the web code to make the updates. Keep reading how to evolve snom.

We need that the updates (for example, new blog posts) are stored in a database, and then the frontend shows them without touching any code. Well, that’s exactly what PHP is for and how it works.

How does PHP work?

Every time a user visits a website written with PHP, the following happens:

• Upon entering, a request is sent to the server.
• The server receives the request and looks for the page to deliver.
• If the page contains PHP, it is processed.
• The server executes the PHP code of the page and prepares the final result, the HTML.
• The HTML page is sent to the user.

Graphically, the operation of PHP can be summarized as follows.

Suppose we have a website with the following code. I have placed the HTML in blue and in green what would be the PHP, (I clarify that the PHP is not written like that, it is only to simplify the example)

<! DOCTYPE html>

<html>

<head>

<title> Example </title>

</head>

<body>

Right now, there is <? Php

How many users are browsing the server?

?>  browsing the web.

</body>

</html>

As explained above, when a user enters, a request will be made to the server. Upon finding the line of PHP code, it will be processed.

The server will ask how many users are browsing. Suppose the result to that question is 25 users. Then that will be the answer that will be sent. As a fine result, the next processed HTML is returned.

<! DOCTYPE html>

<html>

<head>

<title> Example </title>

</head>

<body>

There are currently 25 users browsing the web.

</body>

</html>

Once the browser interprets the HTML code, the final result will only be the text:

There are currently 25 users browsing the web.

In the example, the server’s request was the number of users online, but this could have been to show the last blog entry or comment, the number of times content shared on the networks, etc.

The function of PHP in WordPress

WordPress is a content manager that uses several programming languages. As you may be imagining, PHP is one of them. To say “one of them” is an understatement. PHP is the lifeblood of WordPress, fueling most of the web.

If you explore the compendium of folders that make up any WordPress theme, you will find folders of the type; sidebar.php, header.php, comments.php, and the most popular of all funtion.php. The first controls how the sidebar, header, and comments look and work, respectively. While the folder funtion.php accumulates functions that our theme will use of the various utility.

The moment someone visits your website, the web server will take all those separate PHP files for different areas of the topic, put them together, and deliver the completed HTML output to the visitor’s browser. Yes, yes, all that happens every time you visit a WordPress website.

As a user of the most popular CMS, you can do without knowing about this programming language. But the wide utility that PHP has in WordPress makes it worth it, at least, to know the least.

Well, with this, I finish the post. I hope you have understood what PHP is, its usefulness, and how it works.
