mmtuts is a YouTube channel that focuses on teaching beginner and advanced courses in various multimedia related skills.
We plan to make tutorials available on programming, video production, animation, graphic design, and on software such as the Adobe Creative Cloud programs.

PHP for beginners is a how to series that teaches the PHP coding language to people who are just starting out learning programming. The course teaches how PHP scripting can be made easy and teaches how to build many apps such as a login system, a comment section, how to upload images, how to create users in a website, and much more. Creating dynamic websites with PHP is easy and should not be seen as otherwise, which is why we want to explain the language in a easy to understand way for beginners.

If you have suggestions on new courses, or specific lessons within existing courses you would like to see, then feel welcome to submit them in the comment section or in a private message. ALL suggestions will be seen, but not all will be replied to since we get quite a few every day.

It thought the whole point of hashing was you can never “de-hash” it? You can only re-hash new information and compare with the saved/old hash… I thought it was encryption and decryption where you could get the information back

King Otten says:

Is it also save to hash a password with sha512? And then for comparing them, instead of dehashing you hash the input and compare them with the database. Love this method as well tho 😀

very informative, Thanks :)

Mustafa H. says:

I don’t think password_verify actually dehashes, instead it hashes the input and uses an algorithm to see if it corresponds to the given hash (giving all the necessary like salt and cost)

Vikas Padaliya says:

Can’t find no.41 and 42 , are they missing?

Luca Sarif says:

Active channel making php tutorials? Unheard of – and awesome

Scott Guo says:

You don’t mean that you can actually DE-hash a hashed string right? If a hash can be de-hashed, it’s not a hash anymore.

Marius Mihai Lionte says:
