Attempt to create and autoloader for namespace functions. Maybe it will become a composer plugin, maybe not.

If you want to require certain files explicitly on every request then you can use the files autoloading mechanism. This is useful if your package includes PHP functions that cannot be autoloaded by PHP.

The Goal of this package is to not have to do this for functions.

{
  "autoload": {
    "files": [
      "src/MyLibrary/functions.php"
    ]
  }
}

• first version can lazy load the files
• hook into dumpautoload to create cached files of functions loaded.

PHP throws fatal error when function is not found. No handler can be hooked up to this error to autoload the function.

PHP Fatal error:  Uncaught Error: Call to undefined function

• create functions in the functions folder
• without namespaces (the trait will remove them anyway)
• filename match function name
• add phpdoc typehints on root class for ide support

<?php declare(strict_types=1);

namespace MyApp;

use Zodimo\Psr4ForFunctions\FunctionLoaderTrait;

/**
 * @method static int sum(int $a, int $b)
 */
class Math
{
    use FunctionLoaderTrait;
}
 
// usage
$total1 = \MyApp\Math::sum(1, 2);
echo "Total1: $total1\n";

• avoids function name collisions
• separation of code
