How to use it?

Warning, call constructor will not load values, you can:

• use load() function
• use any functions that automatically call load() inside

Simple example

// search .env file
$env = new Environment(__DIR__);
$values = $env->getAll();
$value = $env->get('a', 'defaultvalue');

Check keys and values

// check if a key exists
$env = new Environment(__DIR__);
$isExists = $env->exists('key1');
$isExists = $env->exists(['key1', 'key2']);

// check if value is set with allowed values
$isAllowed = $env->allowedValues('key1', ['value1', NULL, 'value2']);

Complete and Override values

Only type conversion will be done on those variables (no replacement with $).

You have 3 differents flags:

• Environment::GETENV
• Environment::ENV
• Environment::SERVER

Complete is for filling values belong to keys having empty string or no values.
Override is for erasing values belong to keys.
The treatment given by the flags is always in the same order:

1. getenv()
2. $_ENV
3. $_SERVER

You can also use 3 others flags.
Those will inject all keys and values found, your env file is not used for checkings keys.

• Environment::GETENV_ALL
• Environment::ENV_ALL
• Environment::SERVER_ALL

$env = new Environment(__DIR__);

// complete with only getenv()
$env->complete(Environment::GETENV);

// complete with $_ENV then $_SERVER
$env->complete(Environment::SERVER | Environment::ENV);

// override with getenv() will erase values
$env->override(Environment::GETENV);

Enable cache

The file cached will not contains informations from getenv() / $_ENV / $_SERVER

// force using cache (if not exist it will be created)
$env = new Environment(__DIR__);
$env->enableCache();
$values = $env->getAll();

When load() is called?

For simplicity load() is automatically called when using thoses functions:

• get
• getAll
• exists
• complete

Multiline

You can check what kind of endline it using, by default it's PHP_EOL
You can change it with for using <br>

// force using cache (if not exist it will be created)
$env = new Environment(__DIR__);
$env->setEndline('<br />');

Include another .env

Inside .env file you can include another .env file with the @ operator at the begining of the line

Constructor variations

// search .env file
$env = new Environment(__DIR__);

// search dev.env file
$env = new Environment(__DIR__, 'dev.env');

// search .env file in folders __DIR__ then '/usr'
$env = new Environment([__DIR__, '/usr']);

// search dev.env file in folders __DIR__ then '/usr'
$env = new Environment([__DIR__, '/usr'], 'dev.env');
