Prerequisities

PHP version requirements: PHP >7.0

PHP extension: mbstring

Use use Codervio\Environment\EnvParser declaration for parsing dot env files.

Use use Codervio\Environment\EnvEditor declaration for edit and manage dot env file.

A [requirements] - Requirements and auto detect encodings script automatically can check mbstring extension and automatically detects encoding types.

Usage

Example of fetching env variables and loading into global super variables like $_ENV, using function getenv() or directly using instance:

If on a file example.env contains a data:

After loading instance it can be fetching a variable:

Returns a result will automatically detect type of getting env variables:

Or get a result using env variables globally:

Returning a result

A result returns in following orders:

• using apache_getenv() if apache service is configured internally to use only Apache environment
• using getenv() that most Unix systems supports
• using PHP native super globals $_ENV function

It will automatically parse to PHP env functions and super globals so you can access via:

• superglobals functions $_ENV
• superglobals $_SERVER variable
• using getenv() if is enabled by system
• using apache_getenv() if is enabled by Apache service

Changelog

Status of core:

PHP version above 7.0. Quality assurance: Unit tests provided
