What common error messages might occur when attempting to upload files in PHP?

One common error message that might occur when attempting to upload files in PHP is "UPLOAD_ERR_INI_SIZE" which indicates that the uploaded file exceeds the upload_max_filesize directive in php.ini. To solve this issue, you can increase the upload_max_filesize value in php.ini or use the ini_set() function in your PHP script to dynamically set the value before the file upload process. 

// Increase upload_max_filesize in php.ini
upload_max_filesize = 20M

// OR dynamically set the value before file upload
ini_set('upload_max_filesize', '20M');
