  1. According to Wikipedia, 50 4B 05 06 marks the start of the End of central directory header which contains some information about the ZIP file.
  2. The web root is the folder on the server which contains your website. It could be called "www", "htdocs", "html" or a variety of other names. Anything inside that folder can be accessed through HTTP with a URL. If the file is outside the web root, you won't need htaccess to protect it because it's already inaccessible.
  3. CSS and, by extension, W3.CSS take care of styling HTML. How the HTML was generated (using PHP, handwritten or otherwise) isn't really relevant to how it's used. If you're generating HTML with PHP then be sure to give the correct classes to the elements. My recommendation is to separate the HTML from the actual business logic and put it into self-contained template files which are included using PHP after everything has been processed.
  4. There's an :after pseudo-element with a background color the same as the page's background color which is positioned in front of an unsplit border.
  5. I'd have to see your code and what the validation errors say to tell you how to fix it. If you're using microdata attributes it's not going to validate because it's using non-standard attributes. I recommend JSON-LD for structured data.
  6. It says in your editor that the exception occurred in at line 77. You should check to see if the variable row1 is null.
  7. The console should tell you exactly on what line the exception occurred.
  8. You're going to have to tell me what line its on, but usually that means you tried to use an object that wasn't initialized.
  9. The W3Schools tutorials for PHP and SQL have all the information you need. If you need help with something specific in the code you can ask questions about it here.
  10. The syntax source: availableTags is not proper Javascript. If "source" is meant to be a variable you would write source = availableTags; Even if you do assign something to a variable named "source", you're not using the variable anywhere so it wouldn't do anything.
  11. Unless specifically programmed otherwise, the server will serve the same content to everybody. If you have a PHP file that can manipulate files or the database then it's open for everybody to use and is an easy attack vector on your website, if you want to prevent other people from using it you will have to add some form of authentication. In summary, nothing is stopping me from sending a POST request to your web host.
  12. The superglobal is like any other variable in the PHP process, it only exists during the time the script is running. If you want to store its value permanently somewhere you can use a database or write it to a file. If you want to store something for one user during a browsing session you can use PHP sessions.
  13. A super global is available during the execution of the process. What do you mean by passing it to another file? If the file is included, it has access to all the superglobals of the file that included it.
  14. The PHP GD library can't open TIFF files, but it looks like ImageMagick can. If you don't have access to ImageMagick then you'll have to go through the tedious work of building a TIFF reader that parses binary TIFF files and extracts information from them.
  15. The RSS file can go anywhere you want, you just have to tell people where to find it. As I mentioned earlier, you can tell browsers where to find a feed by putting a <link> tag in your HTML page. There's no real best practice as to where to place your RSS feed files. I think RSS feeds have to use absolute URLs in the <link> tags including protocol and domain name to point to the location of the files. If you want a URL like "/feed" for your RSS feed you would have to use URL rewriting on the server, a regular URL would look like this instead: "/feed.xml" or "/feed.rss".
