create_env_local.config

#this goes into .ebextensions-Folder
files:
  "/var/app/current/.env.local" :
    mode: "000644"
    owner: root
    group: root
    content: |

<?php

    echo "Adding\n";
    foreach ($aws_env_arr as $key=>$value) {
        $line = "$key=$value\n";
        echo "$line";
        fwrite($myfile, $line);
