PHP Standards and Coding Styles Followed by EF Laravel Developers

PHP Standards and Coding Styles are important guidelines and conventions that developers follow to write clean, readable, and maintainable PHP code. Adhering to coding standards helps ensure consistency and collaboration among developers working on a project. There are several popular PHP coding standards and style guides.

In this article, I am going to share the coding standards followed by Electronic First Laravel developers.

        // API call
    } catch (\Exception $ex) {
        Log::error('Indentifier', [
            'class' => __CLASS__,
            'function' => __FUNCTION__,
            'message' => $ex->getMessage(),
        ]);

        return response()->json([
            'success' => false,
            'message' => $ex->getMessage()
        ]);
    }
}

try {
    DB::insert(...);
    DB::insert(...);
    DB::insert(...);

    DB::commit(); // All good
} catch (\Exception $e) {
    DB::rollback();
		// Log
		Log::error('ActionName', [
		    'class' => __CLASS__,
		    'function' => __FUNCTION__,
		    'message' => $ex->getMessage(),
		]);
}
