You might have heard about output buffering while you code in PHP. I will tell you what it is and how to use it simply. "Output Buffering" Meaning "Buffering" in computing means store (data) in a buffer while it is being processed or transferred. This is exactly what PHP does too. But, the default mechanism is not this. It is turned off by default i.e : data is not stored in a buffer while it is being processed or transferred.

Are you as crazy as me when developing WebSocket applications ? It’s so awesome to work with WebSockets that will blow up your mind and irritate you at the same time. WebSockets can be used for any real time applications such as : Games Chat News File Transfer And because it’s impact is so vast, we can develop as many applications as we want. But, a problem arises for freebies like me and you.

Besides coding, my other passion is film making. I have already made some films since the age of 8. But those were raw footage and I didn’t edit them. When I was 11, I created an another film and edited it with Windows Movie Maker. I didn’t publish it and it still exist in my computer. Now, after 5 years I decided to create another film. This time with the help of my friends.

Take PHPUnit as an example. You can install it using Composer doing this : composer require phpunit/phpunit This will install a phpunit shortcut in vendor/bin directory. This obviously means you can run it. But, you would have to point to the exact location of the phpunit file to run : /home/username/mysite/vendor/bin/phpunit phpunit.xml But, that’s long and uncomfortable. And you would have to install PHPUnit separately for each projects. I’m gonna tell you how to install binaries globally as well as running it simply.

Today is Earth Day, a special day dedicated to our mother Earth. I didn’t knew about this day until I saw the Google Doodle today morning at 12:15 (around-ish). When I looked it up, I saw the ways to participate in this event : Walk to work, cycle or take public transport Cycle ? That’s my favorite thing besides coding. It’s a way I could relax and exercise without losing the fun.

Suppose you want to display something randomly in a news feed, or pick random elements from an array, or anything random in general. Programming Languages are used to define the way how something must be done. Hence in a technical way, it can’t do things randomly on it’s own. Otherwise it would be an AI (Artificial Intelligence). Doing random things is not done at compiling, but in execution. In case of PHP, this doesn’t matter as it’s an interpreter.

If you are reading this post, you should have seen the new UI of my blog. It’s a custom made theme created in a week during the exams. It’s similar to the old theme because, I liked it colorful and dark at the same time. I’m a Batman fan and black is good for the eyes. As a programmer, you don’t want to hurt your eyes. The theme is named "Subin’s Blog V2".

I have mentioned before about my new project Lobby – A Web Operating System. I have been developing it for the past 1.5 years in my free time. It has been partially completed. To learn more about it, I request you to read this. I’m writing this post to request you to vote for the package Lobby in PHPClasses. If Lobby win it, more people would know about Lobby and I can develop the project further.

Say you’re running a process that runs in the background. It’s better to not let the user lose their patience and tell them when it will finish. But, you have the time remaining in seconds. If we show the user : 567 seconds to complete He/she (user) would have to take a calculator and convert it into minutes or hours. Or if the guy/gal is not a math genius, he would close the UI and say "What the Hell ?

Say you were displaying the size of a file in PHP. You obviously get the file size in Bytes by using filesize(). You won’t have any idea what the file size is if you read it in Bytes. Bytes is useful for file transmission in a network, but not for human usage. So, it’s better to convert it to human readable form.The circled areas show the converted size from Bytes.
