superglobals - Are few of the server variables been added and few have been removed in PHP 7?

Hey there,

I've been exploring PHP 7 recently, and I can share my personal experience regarding the changes in superglobals. Interestingly, PHP 7 didn't introduce any new server variables to the superglobal $_SERVER array. So, the variables you were already familiar with like $_SERVER['REMOTE_ADDR'] and $_SERVER['REQUEST_METHOD'] remain the same.

However, there were a few server variables that got removed in PHP 7. One important variable that's no longer available is $_SERVER['HTTP_PROXY_CONNECTION'], which used to provide information about the client's proxy connection. If you relied on this variable in your code, you might need to find an alternative solution in PHP 7.

I hope this sheds some light on the changes in superglobals in PHP 7. Let me know if there's anything else you'd like to know!

Hey everyone,

I've been working with PHP 7 and thought I'd share my personal experience with the changes in superglobals. In PHP 7, I haven't come across any new server variables added to the $_SERVER superglobal. So, the familiar ones like $_SERVER['REMOTE_ADDR'] and $_SERVER['REQUEST_METHOD'] remain unchanged.

However, there were a couple of server variables that got removed in PHP 7. For example, $_SERVER['SCRIPT_FILENAME'], which used to provide the absolute path of the executing script, has been replaced by $_SERVER['PHP_SELF'] to obtain the same information.

It's important to note that while additions or removals to the superglobals have taken place in PHP 7, this might not be an exhaustive list. It's always a good idea to consult the PHP documentation or refer to the official PHP manual for a comprehensive understanding of the available superglobals in PHP 7.

I hope this helps! If you have any further questions or insights, feel free to share.

Hey there,

From my personal experience with PHP 7, I can confirm that there have indeed been some changes to the superglobals. In terms of additions, one new server variable that has been introduced is $_SERVER['HTTP_HOST'], which gives you the hostname of the current request.

Additionally, PHP 7 has removed a few server variables that were present in previous versions. One notable removal is $_SERVER['SCRIPT_FILENAME'], which used to provide the absolute path of the currently executing script. In PHP 7, this information can be obtained using $_SERVER['PHP_SELF'] instead.

I hope this information helps you out. Let me know if you have any further questions!
