Simple Dotenv Parser

small parser for .env files

normal parsing

# .env file
KEY1="This is a string"
KEY2=234
KEY3=4.5
KEY4=TRUE
KEY5=OFF

# php file
use TK\Dotenv\Dotenv;

$content = file_get_contents("./.env");
$actual = Dotenv::parse($content);

# output
$actual = [
    "KEY1" => "This is a string",
    "KEY2" => "234",
    "KEY3" => "4.5",
    "KEY4" => "TRUE",
    "KEY5" => "OFF",
];

parsing with conversion

# .env file
KEY1="This is a string"
KEY2=234
KEY3=4.5
KEY4=TRUE
KEY5=OFF

# php file
use TK\Dotenv\Dotenv;

$content = file_get_contents("./.env");
$actual = Dotenv::parse($content, true);

# output
$actual = [
    "KEY1" => "This is a string",
    "KEY2" => 234,
    "KEY3" => 4.5,
    "KEY4" => true,
    "KEY5" => false,
];

conversion

The parse can convert some values to php primitive types, otherwise all values are string.

booleans

these values will be converted to booleans (case insensitive):

• truthy_values = ['true', 'yes', 'on']
• falsy_values = ['false', 'no', 'off']

numbers

these values will be converted to numbers:

• integers (e.g. 3 or 23424)
• floats (e.g. 5.76 or 43234.3453)
• hexadezimal only with prefix 0x (e.g. 0xa0 to 160)
• binary only with prefix 0b (e.g. 0b110011 to 51)
• octal only with prefix 0o (e.g. 0o77 to 63)

null

these values will be converted to null (case insensitive):

• null
• none
