What potential issues can arise when trying to upload files larger than 2GB using PHP on a 32-bit architecture?

When trying to upload files larger than 2GB using PHP on a 32-bit architecture, the main issue that arises is the limitation of the 32-bit architecture which restricts the maximum file size that can be handled. To solve this issue, you can switch to a 64-bit architecture or use a workaround by splitting the large file into smaller chunks during the upload process.

// Set maximum file size limit to 2GB
ini_set('upload_max_filesize', '2048M');
ini_set('post_max_size', '2048M');
ini_set('memory_limit', '2048M');
