What are common issues encountered when uploading large files using PHP scripts?

Common issues encountered when uploading large files using PHP scripts include exceeding the maximum file size allowed by the server configuration, running out of memory during file upload, and encountering timeout issues due to the long upload process. To solve these issues, you can adjust the PHP settings to allow larger file uploads, increase the memory limit for PHP scripts, and extend the maximum execution time for the script. 

// Increase maximum file upload size
ini_set('upload_max_filesize', '20M');
ini_set('post_max_size', '20M');

// Increase memory limit for PHP scripts
ini_set('memory_limit', '256M');

// Extend maximum execution time for the script
set_time_limit(300); // 5 minutes
