24/05/2019 - DOCKER, PHP, NGINX
Eğer PHP-FPM and Nginx loglarını birbirlerinin aynısı olacak şekilde JSON string haline getirmek isterseniz, aşağıdaki örneği kullanabilirsiniz.

PHP-FPM logunda request ID girdiside olduğundan, aşağıda da fastcgi_param HTTP_X_REQUEST_ID $request_id; girdisini kullanıyoruz.
server {
listen 80 default_server;
server_name localhost;
root /app;
index index.php;
location ~ \.php$ {
try_files $uri =404;
fastcgi_pass wait_php:9000;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param HTTP_X_REQUEST_ID $request_id;
}
}
Eğer error_log off; girdisini silerseniz, PHP ile ilgili hatalar Nginx konteyner tarafından gösterilecektir. Ben şahsen her konteynerin kendi loglarını göstermelerini tercih ederim, bu nedenle girdiyi silmiyorum.

Loglarda her hangi bir değişiklik olup olmadığını veya daha fazla ortam değişkenlerine ulaşılıp ulaşılamayacağını kontrol etmek isterseniz, clear_env=no girdisini kullanabilirsiniz.

PHP log formatı C, d, e, f, l, m, M, n, o, p, P, q, Q, r, R, s, t, T, u seçeneklerini sunar ve herbiri % ile kullanılırlar. Örnek: %C. Fakat, e (Nginx server fastcgi_param vars ve PHP-FPM server $_SERVER değişlenlerini temsil eder) ve o ("header" çıktılarını temsil eder) biraz farklıdırlar bu nedenle %{VARIABLE_NAME}e şeklinde kullanılırlar. Örnek: %{REQUEST_URI}e. Nginx yapılandırma değişkenleri burada listelenmiştir.
PHP'nin standart formatı "%R - %u %t \"%m %r\" %s" şeklindedir ve 172.22.0.3 - 26/May/2019:10:57:14 +0000 "GET /index.php" 200 çıktısını verir.
Sadece göstermek amacıyla log seçeneklerininin hepsini kullanırsanız, aşağıdakine benzer bir sonuç alırsınız.
access.format = '{"C":"%C","d":"%d","f":"%f","l":"%l","m":"%m","M":"%M","n":"%n","P":"%P","p":"%p","q":"%q","Q":"%Q","r":"%r","R":"%R","s":"%s","T":"%T","t":"%t","u":"%u"}'

Her ikisinide birbirlerine benzetmek için elimden geleni yaptım ama iyileştirmek sizin elinizde.
