Cannot use getallheaders () in nginx, Call to undefined function getallheaders () error will be reported

In an API environment, I downloaded a suite to test, but after setting the file according to the example, it could not run properly and kept reporting 500. later, I went to LOG and found that the error message was

"Call to undefined function getallheaders ()" is a built-in function that can't be found.

Later, I found that many people have the same problem in stackoverflow. The reason is that because this function is dedicated to apache, it does not work properly in the nginx+php-fpm environment, and the solution is very simple: add a getallheaders function yourself, as follows

If (! function_exists ('getallheaders')) {function getallheaders () {$headers = array () Foreach ($_ SERVER as $name = > $value) {if (substr ($name, 0,5) = = 'HTTP_') {$headers [str _ replace ('','-', ucwords (str_replace ('_','', substr ($name, 5)] = $value;}} return $headers;}}

The program will run.
