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.
Informations about the package dotenv
DotEnv
Package which enables to load environment variables from multiple .env files at multiple locations
This package is a work that derived from package published by vlucas/phpdotenv with some additional functionality such as handling multiple .env files and setting up variables using instance of the class.
Installation
Install package using composer
Usage instructions
To use the plugin you'll need to have at least one .env file i.e.
You load all your .env files when instantiating the SSD\DotEnv\DotEnv object.
You can pass a single .env file, path to a directory with .env.* files or multiple paths / directories
Loading variables
To load process the variables there are two methods load() and overload().
The load() method will only set the variables that do not already exist, while overload() will set them all - overwriting any existing ones.
Required variables
To ensure that your system has all necessary variables available you can use required() method, which takes either a single variable name or an array of required variables.
If any of the required variables does not exist in any of the .env.*files - system will throw a RuntimeException.
Returning contents of .env file(s) as array
Use toArray() method to fetch the contents of the .env file(s), with or without setting up the environment variables.
Obtaining value stored in the variable
You can use a static get() method on the DotEnv object to retrieve the value stored in a given environment variable.
When you associate the string true, false with the variables within your .env file, they will automatically be converted to boolean true / false when using DotEnv::get.
The same applies to the variable with null string, which will return null value.
If you specify a variable without any value associated (MY_VARIABLE=) - it will return an empty string ''.
You can provide a second argument to the get() method, which will be returned if variable was not found.
The default value can be of a scalar or a Closure type.
Checking if exists and equals
You can check if variable exists by using has() and whether it stores a given value by using is() methods.
Setting variables
Variable referencing
If there is a variable that you'd like to inherit the value of you can use its name wrapped within the ${..} i.e.
