Is it necessary to adjust PHP code for uploading larger files, or is it primarily handled by Apache?

When uploading larger files in PHP, it is necessary to adjust both PHP settings and Apache settings. In PHP, you need to increase the values for the `upload_max_filesize` and `post_max_size` directives in the php.ini file to allow larger file uploads. Additionally, in Apache, you may need to adjust the `LimitRequestBody` directive in the server configuration to ensure that larger files can be uploaded without any issues.

// Adjust PHP settings for larger file uploads
ini_set('upload_max_filesize', '20M');
ini_set('post_max_size', '25M');

// Adjust Apache settings for larger file uploads
// Add the following line to your Apache configuration file
// LimitRequestBody 26214400
