How can PHP developers adjust the max file size and post size settings to accommodate PDF uploads?

To accommodate PDF uploads, PHP developers can adjust the max file size and post size settings in the php.ini configuration file or within their PHP script using the ini_set() function. By increasing these settings, developers can allow larger PDF files to be uploaded without encountering size limitations.

// Increase max file size limit
ini_set('upload_max_filesize', '20M');

// Increase post size limit
ini_set('post_max_size', '20M');
