env

Simple library to get environment variables converted to simple types. This library is just a fork of oscarotero/env.

Example

// Using getenv function:
var_dump(getenv('FOO')); //string(5) "false"

// Using Env:
var_dump(Env::get('FOO')); //bool(false)

Available conversions

• "false" is converted to boolean false
• "true" is converted to boolean true
• "null" is converted to null
• If the string contains only numbers is converted to an integer or float
• If the string has quotes, remove them

Options

To configure the conversion, you can use the following constants (all enabled by default):

• Env::CONVERT_BOOL To convert boolean values
• Env::CONVERT_NULL To convert null values
• Env::CONVERT_NUMERIC To convert numeric values
• Env::STRIP_QUOTES To remove the quotes of the strings

The following settings allow to specify where to get the values (only the first two are enabled by default):

• Env::USE_ENV To get the values from $_ENV
• Env::USE_SERVER To get the values from $_SERVER
• Env::USE_FUNCTION To get the values from getenv()

// Convert booleans and null, but not numbers or strip quotes
Env::$options = Env::CONVERT_BOOL | Env::CONVERT_NULL;

// Add one more option
Env::$options |= Env::USE_FUNCTION;

// Remove one option
Env::$options ^= Env::CONVERT_NULL;
