23: How to include documents in PHP | PHP tutorial | Learn PHP programming

How to include documents in PHP – Learn PHP backend programming. Include is used in PHP to attach or insert other files in a file. This is especially helpful when we want to split apart sections of a website page to make it easier to make changes.

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.

Dewald Kunz says:

include_once prevents a same named file to be called twice which can cause errors. let’s say you include “library.php” and include “start.php” but in “start.php” the “library.php” has already been included. then you called “library.php” twice which cause errors.

what would be the point of including php with functions in your html? I thought only javascript can interact with the DOM?

Adrian Dinca says:

Why using the < ?php ?> adds a margin-top and margin bottom ? Can I style it with css or something? How do I remove it ?
