Piping Emails to a Laravel Application

Core points Laravel's command line tool Artisan can be extended to receive raw mail and use it in applications. This involves creating a new command, such as php artisan email:parse, which can be registered and executed in Artisan to retrieve the original message from the IO stream.

The parsed mail can then be easily stored in the database. This setting can also handle any attachments in the message. After searching for attachments, you can create a file system object to save the file on the server

Implementing infinite scrolling includes creating basic HTML and CSS layouts, setting up Ajax modes for processing requests, appending new data to the page, and ending processing data.

Core points Gettext is a popular method for translation management of PHP websites, but it has a significant drawback: Apache caches translations, which means that unless the engine is restarted, updates to translated files will not be visible. This is especially problematic on shared hosting, as administrator privileges are often not available. Audero Shared Gettext is a PHP library that allows developers to bypass Apache's cache of translations loaded through the gettext() function. The library uses a simple trick to create a mirrored copy of the translation file, tricking Apache into thinking it as a new, irrelevant translation, thus avoiding caching issues.
