PSR Standards

The PHP Framework Interop Group (PHP-FIG) introduced PHP Standard Recommendation (PSR) standards to provide a uniform and interoperable set of coding practices for PHP developers. PSR standards cover a variety of coding aspects such as code style (PSR-1, PSR-2), autoloading (PSR-4), and more. The PHP community widely accepts these standards contributing towards writing clean and easy-to-follow code.

Here's a snippet to illustrate the PSR-4 autoloading standards in PHP:

// Register the autoloader
spl_autoload_register(function ($class) {
    // Convert namespace to directory structure
    $class = str_replace('\\', DIRECTORY_SEPARATOR, $class) . '.php';

    // Get file if it exists
    if (file_exists($class)) {
        require $class;
    }
});
