dotenv: readEnvFile()

A simple implementation of https://github.com/vlucas/phpdotenv

This is not a functional replacement, but a very simple implementation of the basic functions.

It is recommended to create a .env.example example file that is checked into the repository. The .env should NEVER be checked into anything

How to install

composer require gullevek/dotEnv

Run it

Create a .env file in the current folder. Create a file like below

require '../vendor/autoload.php';
gullevek\dotEnv\DotEnv::readEnvFile(__DIR__);

All data will be in the $_ENV array

How it works

Put the function where it is needed or put it in a file and load it.

if not parameter is given it will use __DIR__ as base path. Second parameter is file name override. Default is .env

Data is loaded into _ENV only.

If there is already an entry in _ENV then it will not be overwritten.

.env file example

A valid entry has to start with an alphanumeric string, underscores are allowed and then have an equal sign (=). After the equal sign the data block starts. Data can be quoted with double quotes (") and if this is done can stretch over multiple lines. The openeing double quote must be on the same lign as the requal sign (=). If double quoted (") charcters are used it will read each line until another double quote (") character is found. Everything after that is ignored.

Any spaces before the variable or before and after the equal sign (=) are ignored.

Line is read until PHP_EOL. So any trailing spaces are read too.

Any line that is not valid is ignored.

# this line is ignored
SOMETHING=A
OTHER="A B C"
MULTI_LINE="1 2 3
4 5 6
7 8 9" ; and this is ignored
ESCAPE="String \" inside \" other "
DOUBLE="I will be used"
DOUBLE="This will be ignored"
