Im happy to see this video on helping get organized. It helps avoid a backwards approach. What brought me here was my need for connecting a partials folder, having broke down my base html. Then the files started piling up, and I needed to get organized quick before I get too deep in the mud. I blindly tested organizing my files into folders thinking something gotta work. Then I found that include() is rendered useless if including from outside of the main directory. So I thought the approach spl had something to offer and learned the basics but this really answered my question towards modeling my organization. I just need to get my bootstrap to work in the subdirectories to stay organized. So I will do some playing around, something will give and somethings gotta work. Right now is the least amount of pressure in my studies learning code, mainly because I'm getting to freestyle variables after lots of practice, and it opens new doors in my mind, and really fades the struggles of learning. Rather than completely focused on class and learning to copy that; if finally get a chance to code some projects that are unique to me, and have more time to explore troubleshooting rather than worrying about passing grades in my studies, and all the hard work being able to read the code without blindness, just makes you feel worthy to explore the troubleshooting world without getting lost, and having abilities to understand the troubleshooting world. It's intriguing to me to find friends that are making these kinds of videos because are abilities really are questions that are a needle in a haystack. Thanks, I will post an update. About the solutions to my own answers I am searching for this help is leading me towards.

Thanks for this detailed tutorials, you are the only one that made me understand what name spaces means and why it's needed, it's very clever idea, and you simplified it a lot, Honesty more I watch a lot of YouTubers from India doing tutorials about PHP and other technical stuff, most of them were on hurry or skipping important stuff beginners need it, you are the only one explain everything step by step.

[minhazulpr]

Wow! It's awesome. Nice explanation. Thank Your for your effort.

[pavanobhan]

Thank you, for those who have question on how to include test class, just give it namespace "test" and then, use it inside psr-4 as
"test\\": "./"
Here "./" means same directory as composer.json
and if you want to include everything automatically, just use the below code:
"autoload": {
"classmap": [
"./"
]
