PHP Array Data Type - Indexed, Associative & Multi-Dimensional Arrays - Full PHP 8 Tutorial

In PHP you can have regular index-based arrays also known as indexed arrays, you could also have arrays with custom keys also known as associative arrays & can have arrays within arrays which are called multi-dimensional arrays. You will learn all that you need to know about arrays to get started using them goes over how arrays are indexed by default & how re-indexing happens. Also, you will learn how to check if an element exists in an array at the specific key & the difference between array_key_exists & isset().

I'm still here commenting on your videos!
You are really making my path to learning PHP much easier than I thought it would be.
You did an amazing job, really.
Thank you!

This is not a course about how to program in PHP, but how to do it with love and best right way!
Thanks forever!

I've never seen a tutorial so quick yet thorough and understandable at the same time. You covered everything in such a short amount of time while keeping it clear.

Excellent, excellent video. The whole series actually. This would be my go-to suggestion for new or experinced devs

[KaraSuraDraw]

I now understand why my tutors in school hammered us on the fundamentals of programming. My fundamentals are good right now and I don't find it hard to switch to another programming language anymore. Of course, I don't know the ins and outs of that programming language, but I can build things as soon as I know the syntax of the language I am working with. Just like now, I can just go fast through your videos. Just wanted to let you know that your videos are very clear for beginners. Thank you for this series, I think I will learn when I get to your more advanced stuff about classes and such things.

This series is so well done, I'm amazed. Well paced, well explained, and so complete, there are infos that I couldn't find in any other course, probably not for total beginners, but definitely of a quality that is very rare to find.

[jewgienijbrzozowski]

Best stuff for learning php I got in to so far! I must say I feel lucky I got here somehow.

[jessieren]

This is the second time I have watched this video. And I have a deeper understanding of some knowledge.

[alnahian]

Whoop! This was a long one 😄

Never knew I could use something like, [...., 30 => 'value', 'other', 'another'....]

[nielsmartens]

Thanks for this amazing video! They don't teach it like this in school.
