What are common issues faced when implementing an upload feature in PHP?

One common issue when implementing an upload feature in PHP is handling file size limitations. To solve this, you can set the `upload_max_filesize` and `post_max_size` directives in your php.ini file to allow larger file uploads.

// Set maximum file size limit in php.ini file
upload_max_filesize = 10M
post_max_size = 10M
