getallheaders | PHP getallheaders | User Interface library

Finally, after two days work of debugging, I made it work completely. This is how I used it in my scenario.

nginx conf:

I want to have properly implemented header parsing in my app. However, for example, let's have headers such as:

I have a php script which is being called in an angular project. I always get the response code as 0. I can find the request headers in chrome debugging section, but when i see in script it a always empty. Also the php script is called twice with request method 'options' and 'get'. Iam not able to proceed further to get the details. Iam working on a windows , PHP7,iis server.

I was given this simple script in python

Im developing an API in php, and i ran into a problem, basically http_response_code(int $code); behaviour is unpredictable, it just always gets sent at all costs if present anywhere in the code, and after that, naturally i cannot set another http_response_code(int $otherCode) as headers are already sent. I do not know what i am doing wrong, but i think i can boldly assume that http_response_code(int $code); can be used conditionally because it makes all the sense for me. My question is, how this problem should be solved? I have to use the correct response codes, is there a working alternative which does not use rng to decide if it obeys an if statement?

PHP version is 7.4.5

smol version:

Using php 7.2

I'm new to laravel. I have a controller where I just want to get the value of Authorization from the header. I saw other stack overflow answers that suggest I use $request->header('Authorization'). But doing so gave me the error:

I hope that this question will make sense for everyone so here goes. I have a Singleton HttpClient manager class that upon instantiation will Authenticate against Windows Live (Microsoft Auth)

After a while of inactivity (lack of requests), however, this authentication becomes stale and subsequent requests to URL's return a page requiring me to sign-in. My question is essentially, how should I handle re-authenticating to the Server? Should I have another thread that periodically makes get requests and checks to see if the sign-in page is returned, then re-instantiating the HttpClient? Please let me know what best practices there are for this.

Here is a snippet from my connection manager class that performs the authentication:

I have [mostly] successfully migrated away from a WAMP PHP environment onto a LAMP environment and all works fine, except I've spotted that when I post special characters to the php, then on the WAMP I get the posted results, but on the LAMP I get a scattering of  characters in my results).

I have a simple php demonstrator page as follows:
