Description

This course will discuss what global variables are in PHP and how they differ from local variables. The student will also learn how to use the $GLOBALS associative array instead of the Global keyword. Explanations will be given with specific examples.

Some predefined variables in PHP are "superglobal", meaning that they are available anywhere in the script. There is no need to use the global $variable; syntax to access them in functions and methods.

By default, all superglobal variables are always available, but there are settings that can affect this

Drazen Kukoc

Surprisingly, I never thought I would study online. But times are changing and I'm getting my second degree thanks to this platform. I've wanted to start learning programming for a long time! With knowperfectly.com I started my immersion into the world of different programming languages and I love it all!

I have already taken several courses on Knowperfectly. I really liked "Life Plus Club" about health and beauty. The course is compact and not too long. The format is not stressful and sets you up for getting the knowledge you need quickly. And so it is. The classes were never boring, just the opposite - they were dynamic and engaging. The speakers helped to quickly master the material. Thank you for such an interesting course.

Andrea Fol

I was inspired to study by the idea of doing business. Everything I did before was non-digital, and for developing a new project I needed knowledge in the IT-sphere. This is where my paths with knowperfectly crossed. I would especially like to highlight the Internet Profession Club, where classes are conducted by a wonderful theoretician-practitioner, who tells what he himself has encountered and explains it in an easy-to-understand way. I would also note the homework assignments - a real practice with further analysis of mistakes with recommendations.

The psychology courses are really fascinating. The speaker from the module on needs, values and boundaries explains the material very clearly. I’d like to keep talking to her, listening to her, getting answers to the questions I am interested in

I am taking my 5th course on the platform so far. All courses are picked here with all responsibility and care. I've never had any problems with payment, refunds or access to my account with lessons and lectures. Thank you for such a useful source of knowledge

Before becoming a homemaker and mother of two children, I worked as a web designer. The kids have grown up so there is more free time to spend. However, technology is evolving, so I had to learn Figma to get back into the profession. I am now a web designer again, just working as a freelancer for a few hours a day. Thank you knowperfectly!

Florian Martinez

I've recently finished a course on SEO. Loved it. What I valued were various excel templates with formulas, which would make the work easier in the future. I would point out the lecture about traffic planning as well. The materials were really useful
