PHP Header exists but cannot retrieve

I am using this method to make apache header request work in nginx.

if (!function_exists('apache_request_headers')) { 
    function apache_request_headers() { 
        foreach($_SERVER as $key=>$value) { 
            if (substr($key,0,5)=="HTTP_") { 
                $key=str_replace(" ","-",ucwords(strtolower(str_replace("_"," ",substr($key,5))))); 
                $out[$key]=$value; 
            }else{ 
                $out[$key]=$value; 
            } 
        } 
        return $out; 
    } 
}

I retrieve the header like so $headers = apache_request_headers(); and use an array to hold json. 

$response=array()
$response["error"] = true;
$response["message"] = $headers;

The code below is what is inside of the $response array variable:

error: true

}

My problem is, I need to grab X-ApiKey from $header, but using $api_key = $headers['X-ApiKey']; returns nothing, but as you can see, X-ApiKey exists in $header. Can someone please tell me what I'm missing here?

Looks like you are using the wrong variable name. Variable names are case-sensitive.

The response returns the following (small k in Apikey): X-Apikey: "bca0de3e7c10cb6623ef00021caf9450"

while you are using capital k $api_key = $headers['X-ApiKey'];

Try the following: $api_key = $headers['X-Apikey'];

$response["message"] is a string. First try to explode it and then access it -

$temp = explode('X-Apikey:', $response['message']);
$temp1 = explode('X-Http-Proto:', $temp[1]);
var_dump(trim(str_replace('"', '', $temp1[0])));

Output

string(32) "bca0de3e7c10cb6623ef00021caf9450"
