Small PHP script that allows importing a Plex library directly into Radarr

gen.php

<?php

// put this file in a web-served directory with a server that handles PHP files
// use the URL of the field as the "Trakt API" URL in Radarr
// (e.g. http://yourserver/somepath/gen.php)

// put your Plex library path here (escape eventual spaces using backslashes)
$res = `sqlite3 /storage/plexmediaserver/Library/Application\ Support/Plex\ Media\ Server/Plug-in\ Support/Databases/com.plexapp.plugins.library.db "select guid from metadata_items where guid like 'com.plexapp.agents.imdb%';" | grep -P 'tt\d+' -o`;
$movies = explode("\n", $res);

echo json_encode(array_map(function($item) {
        return [
                "ids" => [
                        "imdb" => $item
                ]
        ];
}, array_filter($movies, function($movie) {
