+## Docker-compose LEMP
+### Inkluderar
+- nginx -> localhost:80
+- php   
+- mariadb -> mariadb
+- phpmyadmin -> localhost:8080
+
+### HowTo
+
+##### Webbroten
+    www/public
+##### Starta servern (containern) med
+    docke compose up -d
+##### Stoppa servern (containern) med
+    docker compose down
+##### Serverns url
+    localhost
+##### phpmyadmin
+    localhost:8080
+##### Anslut till MariaDB med php
+
+````php
+<?php
+    // Definierar konstanter med användarinformation.
+    define ('DB_USER', 'userName'); // Användare i MariaDB
+    define ('DB_PASSWORD', '12345');
+    define ('DB_HOST', 'mariadb');
+    define ('DB_NAME', 'dbName');   // Databasen som anslutning skall ske till
+
+    // Skapar en anslutning till MariaDB och databasen dbName
+    $dsn = 'mysql:host=' . DB_HOST . ';dbname=' . DB_NAME . ';charset=utf8';
+    $db = new PDO($dsn, DB_USER, DB_PASSWORD);
+?> // Ej nödvändigt att avslut "ren" php med ?>
+````
