PHP stands for PHP Hypertext processor. You can find the manual here:

PHP is known as a Server Side Scripting Language. This means all of the source code stays on a server and is unavailable to people who do not have access to the server. The only thing clients can get access to is the end result of the program.
PHP can be used to develop many systems including user systems and login systems, form validation, database management systems, Content management systems, project management systems, and more! PHP is a great programming language for beginners. In this series, we will be diving into all of the concepts you need to know to start developing with PHP.

Calab. I just discovered your channel. Some of us didn’t grow up with the internet or computers. As far as games, Pacman was the biggest thing going…and the average person didn’t own a computer. Somehow the years have gone by, and we find ourselves as dumb as a cob when it comes to the most simple things beyond web surfing. Some of us don’t even have Iphons or tablets because we find them so intimidating as far as understanding their abilities and functions. Seems so many times when we seek the help and information from others they spew out abbreviations, in web language that sends us in orbit. We break the illiterate scale when it comes to the understanding of these terms and their function. We feel we’ve been living in our own dark age because we found these (even basic) functions so intimidating. This is the first video of yours I have ever watched, and I discovered your RARE talent for breaking things down, so the most unfamiliar of us can understand. Too many people don’t realize the importance of that when trying to teach others. They assume waaaaay too much leaving the viewer (student) in a head spin. You Sir have given people like me real hope in beginning to better understand these things that seem so foreign, and complicated. That my friend is a tremendous gift, in making you a GREAT instructor. I will be visiting your channel many many times, and repeating the views over and over again until it finally sinks in. You are much more than a breath of fresh air, you are pure oxygen to those of us who desperately want to understand. Thank you from the bottom of my heart…you have just met one of your biggest fans. God Bless You.

You should be a teacher lol

Barney Laurance says:

Remember never to put user’s passwords directly in a database – you don’t want to have access to that yourself, and if someone hacks in to your database you don’t want them to access it either. In PHP you can run the password through the password_hash function, and put the output of that in the database instead. That’s much safer because stores something that looks random in the database, and now you can’t tell what the password is if you don’t have it, all you can do is check whether a password that someone supplies when they want to log in matches or not.

I came here because I couldn’t access the backside of my site. This message came up:

Warning: assert(): It is not safe to rely on the system’s
timezone settings. You are *required* to use the date.timezone setting
or the date_default_timezone_set() function. In case you used any of
those methods and you are still getting this warning, you most likely
misspelled the timezone identifier. We selected the timezone ‘UTC’ for
now, but please set date.timezone to select your timezone. in /home/bobs/public_html/administrator/index.php on line 3
