Pull config from .env values or from Laminas config

Install

composer require iampersistent/config-value-component

Usage

 $config = (new GatherConfigValues)($container, 'print');

In the .env file, the first part of the environment name must match the config name (case-insensitive). Each subsequent underscore creates a key in an array of the value.

PRINT_PRINTER=Epson TX-80 

would result in

$printConfig = [ 'printer' => 'Epson TX-80', ];

If there is a default key, the case of that key will be used.

// print.config.php return [ 'print' => [ 'printerType' => null, ] ];

.env PRINT_PRINTER=Epson TX-80 PRINT_PRINTERTYPE=dot-matrix 

would result in

$printConfig = [ 'print' => [ 'printer' => 'Epson TX-80', 'printerType' => 'dot-matrix', ] ];

If there are conflicting values between the config files and the .env file, the .env value will be used

// print.config.php return [ 'print' => [ 'printerType' => null, 'speed' => 'fast', ] ];

.env PRINT_PRINTER=Epson TX-80 PRINT_PRINTERTYPE=dot-matrix PRINT_SPEED=slow 

would result in

$printConfig = [ 'print' => [ 'printer' => 'Epson TX-80', 'printerType' => 'dot-matrix', 'speed' => 'slow', ] ];

Any values in the config that don't have a value in the .env remains as is

// print.config.php return [ 'print' => [ 'location' => 'Room 1', 'printerType' => null, 'speed' => 'fast', ] ];

.env PRINT_PRINTER=Epson TX-80 PRINT_PRINTERTYPE=dot-matrix PRINT_SPEED=slow 

would result in

$printConfig = [ 'print' => [ 'location' => 'Room 1', 'printer' => 'Epson TX-80', 'printerType' => 'dot-matrix', 'speed' => 'slow', ] ];
