Hello,

When using greader API with PHP 7.1, there is some warning in my nginx error log :

*31 FastCGI sent in stderr: "PHP message: PHP Warning: file_get_contents(): Failed to seek to position -1 in the stream in /config/www/freshrss/p/api/greader.php on line 26" while reading response header from upstream, client: 172.17.0.1, server: , request: "GET /api/greader.php/reader/api/0/stream/items/ids?output=json&s=user%2F-%2Fstate%2Fcom.google%2Freading-list&xt=user/-/state/com.google/read&n=10000&r=n HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "xxxx"

With PHP 7.0 this warning don't occur.

It seems that file_get_contents() got updated with PHP 7.1, and FreshRSS php code should be updated : neos/flow-development-collection#821
