You may get confused over choosing Windows or Linux as host operating system in both server and desktop spaces. With focus on aspects of cost, the functionality provided, hardware compatibility, support, reliability, security, existing software, and other factors, here are reasons why Linux can be better option than Windows operating system.
Linux is free and open-source, so can simply change anything in Linux. There are several Linux Distributions (also known as distros) - Ubuntu, Red Hat, Mint, Debian, Fedora.
Linux Shell or Terminal
A shell is a program that receives commands from the user and gives it to the OS to process, and then it shows the output. Linux distributions come in GUI (graphical user interface), but Linux has a CLI (command line interface). To open the terminal, press Ctrl+Alt+T in Ubuntu, or press Alt+F2, type in gnome-terminal, and press enter.
There are a lot of situations where you might need to get the URL of a webpage that any user might be currently visiting. For example, you may require you to dynamically generate the title of a webpage based on its URL. There are many ways in which you can obtain the URL of a webpage.
Calculating the difference between two dates is not as easy as it sounds. There are a lot of things that can go wrong if you are not careful. For example, you have to take both leap years and daylight saving time into consideration. Simply converting two dates to a timestamp and subtracting the values is not reliable in all cases. The PHP DateTime class takes care of all this.
Many times, you have to programmatically resize images. Maybe you have to create multiple sizes of the same image to serve on different devices. Maybe you need to resize images that your users are uploading. You can make use of the PHP’s GD library to resize images in PHP. GD has all the necessary functions to manipulate images so you won’t have to use any other 3rd party library.
Many times, the strings have extra spaces that need to be removed. For example, you might want to replace multiple spaces with a single space or you might want to get rid of all the whitespace in a string. Similarly, you might be planning on stripping all the whitespace from either the left or the right end of a string.
You can upload files on server using a HTML form and PHP. You can upload any kind of file like images, videos, ZIP files, Microsoft Office documents, PDFs, and other files. The uploaded file can be saved in any folder on permanent basis. You can also implement some basic security check like file type and file size to ensure that users upload the correct file type and within the allowed limit.
