FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Config environment loader
Installing
Important notice
All environment variables are stored in static property so any instance of environment would have access to the same set of environment variables.
Usage
where $path is directory where environment file is placed.
Loading environment
To load environment variables from file call $environment->load($filename), where $filename is a name of file. All
variables would be stored locally, not affecting any of $_ENV, $_SERVER and so on.
Additional arguments is load($filename, $safe, $silent). If $safe is set to true variables would not be
overwritten if they are already present. If $silent is set to true no exceptions would be thrown. Function
returns true if environment file wss processed successfully, false in case of any errors.
Reading environment variables
$environment->get($key, $default) returns environment variable if it set, otherwise returns value assigned to default
or return value of callable passed to as default.
$environment->has($key) returns true is environment variable set, false otherwise.
Manipulations
$environment->set($key, $value, $safe) sets value to environment. If $safe is set to true variables would not be
overwritten if they are already present. Passed values of string type it would be parsed (see below), others would be
set as is.
$environment->unset($key) removes variable from environment.
Format
Each line of environment must contain one value, consisting of variable name and its value separated by = sign. Other
words, part of line before = sign would be used as variable name, another part would be value of variable.
For example:
Each value would be parsed according next rules:
String
Each quoted value would be converted to unquoted strings.
Result of $environment->get('DB_HOST') would be '127.0.0.1'.
Boolean
If value is true or false it would be converted to boolean type.
Null
Null values would set to null
Array
Arrays must start with [ and ends with ]. Items must be separated by commas. Each item would be parsed according
this rules. Nested arrays are not supported.
Numbers
If value represents any of number format it would be converted to integer or float.
If parser would not recognise type of value, original string would be returned.
Result of $environment->get('APP_KEY') would be 'base64:0vqkPYSbwPm3MOzdxQJ76Ps6pouZRjN5xPx3b+dm628='.
